Good point... I'll take my video camera..... if the
1050 proves to make good power I'll pull the intake
and machine it to fit the dom but I'm hoping the 850
will be close to right... that way it would be a bit
friendly on MPG on the street.. but I've machined
intakes before to fit a dom....... Randy did you think
that their dyno was a fair dyno when it came to the numbers
(I forget what yours made on it).... I dont need
some BS numbers... just a fair number that I can
figure if my chassis is working right
Mike, I think the numbers Shawn came up with were probably pretty close. I haven't had my car out yet to see what it REALLY makes but hope to soon. My 540 made 830 on their dyno with limited tuning. When Shawn, Sean, and I were planning the build and came up with the parts combo, Shawn said that he had built similar combos when he worked for Chuck and that they made about the same number that mine did. We'll see..... Good luck again! Oh, what are you using for fuel?

Just running 93 octane pump gas... I picked up 15
gals today... how many gals did you go through when
you dynoed

I'd say right at 590, you've got bigger headers and heads and a bit more lift than my little 414.
Cam's in a little early and tight centers which is gonna make massive moves through the middle but the torque may not hold on long enough to get the really big numbers (over 610 or so) up top. That's where I'd put it in a 3000 pound car but I'll bet the rampage might ET bestter with it in a little later, especially with the big headers and the 5's
Never ran the large port M1, I like the Vic 340 ported with the 2" HVH/Wilson 4 hole on mine a lot, I think the short runners of the vic are an advantage on the long stroke short rod ratio combos when the cross section of the port is still fairly small.

With Strokers on the street (or like big automatic B/E bodies when you want to peak the power earlier with an abundance of Head) one of the "secrets" it seemed to take a number of others a while to figure out is to put a big intake lobe in Early to work the head harder sooner. A few years ago I remember reading about Tony Bischoff's 433" CHI headed Windsor that won the Engine Master Challenge...he made like 720hp all in by 6500rpm (best average torque and power from 2500-6500 wins) with real tight Lobe center cam in real early and big heads that flowed in the 380 range.....at that moment I smiled and said, [Email]D@mn![/Email] somebody else done figured it out!   With Mr P's combo all I'm saying is a wider spread and in a little later might benefit the light weight of the Rampage in terms of MPH...it probably doesn't need a ton of torque through the middle as badly as a typical/heavier A body bracket car. a little OT but With strokers if you think about the mechanics of the stroke and the bigger hole you have to fill more air into in the same relative time (compared to a conventional stroke length). you can see that getting the valve higher sooner as the piston sweep past TDC for the intake stroke can help the fill while also closing it earlier can trap more effective displacement....for every degree past BDC the advantage of your big stroke diminishes....because you're giving back displacement at a faster rate per degree of crank rotation.

Well it didnt go well today... let it warm up and all looked good... made a partial pull to 4500 and it made 463 hp and 458ftlbs... it was fat so jetted down 3 jets all around.. made another partial pull and seen it was lean coming off idle so we pulled the PV and plugged it, went up 7 jets, made a 5000 rpm pull and it was down 50 ftlbs... let it stabilize and made another pull going to 5000 and this time had to abort... lost another 50 ftlbs... pulled the filter and cut it open and seen alum partials... they were saying it looked like bearing material so I pulled the pan and a 4 rod caps and a main cap but they were fine.... after that I told them screw it, pull it off the dyno... only thing I can think of is the cam bearings....I'm so pissed right now I wanted to just do a WOT to see what the problem was but that didnt happen... I'll put it back on the stand

 I think the early valve opening is gona limit the peek #s some but the AVE torque is gona be real good, I was wondering how the big M1 was gona work out on 418 cubes under 7k
You guys are forgetting... this engine was build
with junk I had laying around the shop.... it is what
it is... I wasnt gonna buy anything I didnt have to

Dang, it sounds like a problem child. I had to open up the pushrod holes a whole lot when I went to the roller lifters and HS rockers. Even with a thick wall 5/16 pushrod when a 3/8 cleared with ease with the flat tappet and Crane rockers. Something to look at.

To be honest I'd like to burn this SOAB to the ground... I have NEVER had a engine give me this much sh!t... I wanted to do a WOT run and they asked the others there to talk to me.... I think they just didnt want to clean the room up..... screw it

Maybe you should have offered to clean up the room.  Sorry, I know it's not funny but sometimes you just gotta laugh to keep from crying. Hope it's nothing major.

Loosing 100 ft lbs in that short of a time and you should be able to see the problem somewhere. You will have to pull ALL the rods and mains to be sure. If the cam spun freely when you put it in, it's not likely the problem. How do the cyl walls look from the bottom? Did you check the rotational torque of the short block when you put it together last? Should have been in the neighborhood of 25 ft lbs. How was the oil pressure? Stay positive. You will find it - hopefully without too much damage. At least you didn't have to deal with taking it in and out of the car again. 
I had to go with 4.080 rings on a 4.076 bore so they
were tighter than normal and it ended up at 32# rotational
which is a bit high but I knew where that came from...
the cam spun freely when I installed it... I didnt
look at the bottom of the bores... by then I was done...
this isnt the first engine for me but this one sure
is giving me sh!t... I ran all sorts of scenarios
through my head this evening but I quit guessing...
I'll find out Friday when I get it home and on the stand
I was so pissed at that point I just quit... nothing
else could be done there on the dyno... why pay for
more time..... granted I didnt pull all the caps
but I doubt its a rod... I could slide them easy
on the journals.... but hell maybe I dont know sh!t
now... of over about 150 engines I've built, this one
is killing me..... and its my own... thank goodness
its not some one elses
