Close up of the ignition plate I built for the back of the motor. This makes it more self contained so we don't have to rewire the dyno cell. Thanks to the guys at MSD for the parts and tech support.

that's cool that your son is interested- mine couldn't care less. good luck with that motor, i hope you blow it up (the dyno)!
for what is the good life if not doing things thoughtfully?

Is this a Flat cam, or a roller?..Cant wait for some details...  I'm sure the boy will be pumping out Custom Billet peices before ya know it LOL  That's good that he shows a interest in that stuff, I'm hoping for the same with Mine

what kind of testing will you be doing with the MSD? is it a comparison test against something else?
tell us more about the "ratio testing" as well. what's that all about, just to see if they're really as advertised, or how much difference they make against something else?

moroso makes those gaskets. 93055 is the number. They will last forever unless you do something to them. They work best on machined surfaces and cast valve covers.
One more thing is i only use the center 4 bolts.

you gonna dyno it with that oil pan.. looks like a wet sump pan to me..

With that engine combo Dry sump would never even be a consideration.
Under 1000HP dry sump should not even be in the picture.
Thank you for the data but it does not seam realistic ??

Looking forward to the report on the dry sump. My bet is the gains will start small at 4500 to 5500 rpm, and be very substantial by 6500, awsome by 7500.
One thing a dry sump will always have over any wet pan, oil control on the launch. Even the best wet pans have to lose some hp to windage in the first few feet due to extreme G forces at work. The faster the car, the worse it would be. No dyno can show that. It would be great to do back to back track tests to see how much of a difference there would be in each segment of the run.

Sorry I didn't mean to ruffle you feathers .
Is this a test engine or a engine for your car ?
I will go back in your posts and get up to speed on what you are doing..
Engine looks great

I could do back to back wet-sump vs. dry sump testing but I probably won't bother since it takes a bunch of time and costs a bunch of money. Nobody is paying me for this testing so it all comes out of my pocket.
can you do this and sell it to the magazine to make your money back???????

It is a dyno pan so no reason to run a shallow pan when there is room to run a deep one. Usually oil pans work better the bigger they are. Something about the extra volume providing more space for the pumping energy to spread out in I suppose. I don't have test data myself on that theory but plenty of other guys seem to agree that bigger is better when it comes to oil pans. The theory makes sense to me so I just had Charlie build the biggest pan that would fit.

Thanks for the info. I was wondering if we could get a price comparison between wet and dry sumps? Including the cost to mount and plumb them and the accum. tank?

We ran both the Super Victor and the Mopar 337 intake. Also ran 1.70 and 1.85 ratio rocker arms on the intakes. Best power was 1.85 intakes with the 337 intake.
I assumed the 337 intake would be down 15 or 20 hp from the Super Victor but actually the 337 intake made the most power. Not sure why that is the case but it did.
Peak power with the 337 intake was 797 hp. The best pull with the Super Victor was 791 hp. Both of those numbers were with the 1.850 rocker arms. Best pull with the 1.70 intake rocker arms was 780 hp so the bigger ratio was worth about 10 hp.
Carb was rich with the 337 intake so there is probably another 10 hp to be found. We had the carb dialed in with the Super Victor but the 337 intake must be working better since it makes more power with less jet. I'm still having a tough time believing the 337 intake works better than the Super Victor but if you can't trust back to back dyno pulls then what are you going to trust?

The dry sump setup worked perfectly. Oil pressure was nice and solid in the 60 psi range.
This motor has a ton of pulls on it but the Oberg screen looks perfect everytime we take a peek. This motor isn't putting any trash at all into the oil so that is a good sign. It has a lot of 800 hp pulls on it and the bottom end is all stock except for some ARP main studs.

Andy how did you like the new cam compared to what you have been using?

Andy, What was the cam lift with the 1.7 and 1.85 rockers?
Lobe lift on the cam is .393/.401 so with the 1.70 setup it was .649/.661 net lift.
With the 1.85/1.70 split ratio rocker arms the net lift was .706/.661.
This really isn't a very wild cam even with the 1.85 rocker arms. .706 lift isn't anything exotic these days. I was running some fairly mild Comp 26097 valve springs and the motor seemed happy up past 7300 rpm.
We saw the best peak power numbers at 7300 rpm with the 337 intake. Evidently the shorter runners on the 337 wants some more rpm to make power. The first pulls on the 337 intake we didn't turn it enough rpm and the power was down a bit. Then the dyno operator decided to lean on it a bit harder and the power jumped up a bunch.

Interesting, my CamMotion roller is 706/661 with 1.5's. Is there an advantage to running the smaller cam with bigger ratio rockers?

Andy , is there any way you can post the Graphs?
Peak is cool of course but the curve can be a lot more telling/useful. Thanks!
i had an M1 Stage VI standard port RB I bought from BradH that I wound up not using, Brad said Roger Helgessen worked the plenum roof transitions and it really came alive......the most power I've found working single planes has almost always been in the roof/plenum transition, not so much in the port walls themselves.

I'm very surprised on the intake testing results, never would have guessed the 337 works that well.
We were surprised as well. Only thing I can think is that this engine combination liked the shorter runners in the 337 intake. I had to use a 4150 to 4500 adapter since I didn't want to change carbs. Usually the adapter kills a little power but it seemed to work okay in this case.

I had a deep pan on my dry-sump engine as well (one
that I built) and I believe it was better than what
I have on it now (standard dry sump pan, shallow).
Some testing I did on the dyno at Chrysler showed
a improvement with a deep pan but I dont recall the numbers
but it was only like 2 or 3 HP but that was in a lower hp engine

That cam really surprised me. For such short duration at 0.050", on 505 CID, it really made peak power higher in the RPM range than I thought. Obviously the good flowing heads have something to do with that, but I wonder if the cam profile above 0.050" tappet lift is "special". Like you said, it isn't crazy in total lift.
What was the duration at 0.200" tappet lift? I wonder if comparing a lobe made for 1.85 ratio rocker and one for 1.5 is making the duration appear different. ie at the same valve lift (say 0.050 x 1.5 = 0.075" valve) what would the duration comparison look like? MM305S solid at 0.075" valve = 279º, Roller at 0.075" valve (.075/1.85=.041 tappet lift) = ???º (close to 276º?)
And maybe that 337 has more cross section between the plenum and head than the Super Victor? (tapered to same port window obviously) I would think that could be part of it too (505 CID, 7300 rpm, = flow needed).

One of the most influential engine theory books I ever read was called "the design and tuning of competition engines" by Phillip H. Smith http://www.bentleypublishers.com/product.htm?code=G140One thing I read almost 30 yerars ago now has been proven to me time and time and time again....the longer the stroke the shorter distance the motor wants the carb from the intake valve....Part of the reason I always felt the Street Dominator worked so well on long arm strokers is the comparatively short straight "line of sight' shot at the valves compared to say the longer taller victor manifold.....now this may not be the reason that the 337 seems to work better in this application but it may be. Runner length for a given port cross-section produces wall friction at high velocities, long runners are very beneficial for torque production....anyone who's ever driven a 5.0 mustang (3" stroke) can attest to that....but once the stroke (and piston speed) is there any runner length beyond "optimum" becomes a resitence. Strokers by and large generate so much low end (based primarily on volume and especially PISTON SPEED) that they really don't need a lot of runner length. Back in the 80's when the 500" Pro stocks first started covering up their manifolds a big part of that was the trend toward shorter runners and larger plenum areas and was a big departure fro mthe 70's technology tunnel rams. RPM's (again piston speeds) were going up and up and runners got even shorter. Anyway, I thought I'd throw that in....plus it gives me another chance to ask Andy about the Dyno chart question...'cause we all know peak power don't really tell the story like the torque curves do....especially with wide spaced geared automatics!  PS. Mike Jones is local to me...coincidentally I've been thinking about getting with him on my next roller project

Sorry, dyno curves aren't available. The camshaft is an R80393/R82401 lobe set from Jones if you're interested. Ground on 110 centers, installed at 106. www.jonescams.com is the website for Mike Jones.

Thanks Andy!
Any chance you might try the Indy single on it...especially since that was what you ran with the flat tappet solid.
There's a lot in your comment comparing the solid to a roller....when you got a big cylinder all thse extra degrees of valve Dwell ABOVE .200 lift really pay dividends in the power department, you trypically/especially see the roller pull away in the RPM range above the torque peak.

first, when comparing the new cam to the one in the old test, even though the comp cam had much more duration, the lift wasnt in the same range to the new stick with 1.85, is this correct? what i'm saying is, there could have been a bunch more power with cam lift where the heads flow best compared to a stick that holds the valve open under the heads peak flow lift next, is that mopar intake a max wedge port intake like the super victor is? could the 60 hp increase be due to a big dry sump pan? Andy, i love reading your tests but you change to many things and you cant really figure out what is doing what. well, except for the fact that the ugly intake is better than the pretty one

And maybe that 337 has more cross section between the plenum and head than the Super Victor? (tapered to same port window obviously) I would think that could be part of it too (505 CID, 7300 rpm, = flow needed).
I'm leaning towards that explanation, considering the similar Stage VI intake that Bobby (streewize) referred to above had such a large plenum and significant taper in the runners. On a 440, it made big HP, but had a noticeable dip in the torque curve below the torque peak.
I like to see how the MP intake and the Super Victor's torque curves compare across the RPM range, but noticed Andy's "no dyno curves available" reply.

Maybe because he's selling it to one of the magazines for an article?

What kind of work do you have in to the bottom end?
Just what I said in the line you quoted.

what are the differences with the motor between this test and the one where you had the big Comp roller in it?
did you make full pulls with the motor in that other configuration, or were you limited by the dyno capacity(around 800hp as i recall) on that previous test?
IMO, there are way too many differences between the tests you did with the Comp solid vs this test with the roller to draw any real conclusions between the two cams.

Is those just caps? Who's oil pump is that? I was thinking those were just the Inlet/Outlet to your remote oil filter correct? Very nice stuff BTW

It has been a little while since I worked on this 505 motor. Latest update is that I'm pulling the EZ heads off and moving them over to my new 514 motor. I'll be putting the top end off of this motor onto the 505.
So next round of testing will have ported Edelbrock RPM heads, tunnel ram, and hyd roller cam. I'll keep the dry sump setup on there since it is all sorted out and working nicely. I'll have the new setup up and running in a few weeks. Should look wild and I think it will run pretty hard. The power will be down 100 hp or so from the EZ heads but it should be a good street bruiser type of setup.
Basically I decided that I shouldn't keep making 800 hp dyno runs on this stock block bottom end. So I'm moving the EZ heads and Jesel setup over to the 514 motor which is based on a World block. I'll keep the 505 motor around as my standard port head dyno mule. That gives me a std port dyno setup and a max wedge dyno setup. Now I won't have to swap heads back and forth whenever I want to test different intakes and such. The std port head knocks at least 100 hp off and probably more. So this 505 goes back to being a 650 or 680 hp motor which should help the bottom end last a longer time.

As you have shown, a stock block at that power level needs some help such as aluminum rods, aluminum main caps, girdle, something to reduce the chance of cracking cast iron.

Thanks for the information Andy. I know a few people that have better heads then the Indy EZ heads on stock blocks. I am going to point out this post to them and hopefully enlighten them on the possibility that they are driving time bombs.

Yep, I agree. Anything cylinder head that is capable of making more power than the EZ head really deserves an aftermarket block.
I'm going to be interested to see if there is any power difference between what my cracked 505 was making and what the new 514 will make. The 514 will have the same exact heads, cam, intake, carb, etc that I was running on the 505 so the main difference will be the block itself and small changes to the bore and stroke.

Makes me nervous as well. I am spraying a 150 HP shot on mine, and it is making right at 800 HP plus it is in a 4050 lbs car. Ran a 10.59 @ 127 last time out, and that equates to right at 675 HP to the wheels, which assuming drive train loss is about 800 at the crank.
Mine does have a Hughes Girdle, so hopefully this is helping me out some. Wish I would have went with the BCR Products Girdle that includes aluminum caps!
