Did the Holley 1000 have PVs?

Are you going to dyno it with the small tube headers and no other changes? It would be intresting to see how much they would hold it back. Heck, I'd like to see a set of straight 1 7/8" or a 1 7/8" step to 2" to see how it responds.

yes - i was planning on going from the small stuff, to big, but just went right to the top - will make a few other changes before we start swapping to the small tube headers -


also - we went from 1.19 hp/cu with the stockers, air gap and small headers to 1.49 with the MCH's SVC & big headers...

From the jetting it sounds more like a dog leg booster?

TEAL - Stock Eddy Head, Air Gap, 1 5/8" headers & small cam
PINK - SDSS Heads, Victor 340, 1 5/8" headers & small cam
WHITE - MCH Heads, Super Vitcor, 1 3/4 to 1 7/8" step headers, & big cam

interesting to see the graph - the torque really moves up and down the RPM range, but stays at the same level.

That's awesome, now you have shown us "Gay Graph" #2. Just kidding, it's nice to see an overlay on the pulls. It shows a good comparison from a street setup to a race application.

Dave,
I would like to commend you for the outstanding photos and overall job you have done. I am proud to tell people that I had some part in this build and the way you went about it shows a great attention to detail. And for that sir, I thank you.

Rod

Thanks Rod - I knew you would come around on the graphs...lol

I spent today changing the oil, cutting the filter, and running the valves....Looks good and all the rockers didnt need adjustment.

Took readings on cranking PSI on all cylinders - the small cam was 145 - 150 range - the big one is in the 135-140 range - i guess the overlap really take a chunk of cranking compression out.

Ran a leakdown test as well - we were in the 5-6% range on all cylinders, so we have a healthy 430 ready for more testing!

Someone asked about the carb - it has annular boosters -





Plugs looked good - timing marks look good...

nice read.

good numbers too.

what sized valves are in the MCH heads?

Thanks - I appreciate that!


I'd like to pick your brain about a cam for the last setup - what are your thoughts - what would you change?

This sucker still idles at 900 rpm, there is no ports for me to pull a vacuum reading but it's not real choppy -i;ll have to snap a vid


both SD & MCH heads are 2.055 & 1.60 exhausts

I'll have to dig up port volumes as well

Is the super vic ported? That pup is makin some power with conservative flow #s and cam




I gasket matched the intake, and also opened up the flange since it had that goofy overlap into it.

All the numbers were low - I'm not sure what caused that but they were all consistently low. The flow sheet from the MCH's add another 10-15 cfm in there and that is from his bench - I believe the test numbers were at 24" on the bench at the shop, but cant confirm that right now. but we did go into this knowing the numbers were low. I figure that since they are all from the same bench you can get a gauge as to how each stacks up against the other under the same conditions.

we had fun today finding hp - started out at 580@ 6500 - was way lean - needed to jet up ( was at 82 & 86 ) and timing was at 30 ( where the other 2 heads liked it AFR was in the high 13's and low 14's - -

next pull had jetted up to 84 & 88 - made 609 @ 6500 - still was lean - about 13.8:1 - gettin there!


Last run of the day was 34 degrees timing and 88's and 90's - thats when we hit 12.5 afr and 627 @6500







Any chance you recorded the high speed air bleeds

Dave you did a real awesome job with this engine man! I have been following along, and I have to say your attention to detail is great! I always put my engines together slowly like this too, mainly due to time...sometimes wish I could get it done faster, but when you take time to check EVERYTHING its worth it, and your results and work just remind me that its the best way to go.

Very B@DA#% motor! Makes me excited to see what my next one will put out

Dave,

I went all back through this and WOW, what an insightful thread.

I'm trying to extrapolate what to expect when I hit the throttle on my 414 after switching from the Eddie SDSS stage 2's over to the Airwolfs.

My motor has a bit more CR but a lower lift 'endurance type' roller with similar duration,

Your power went up nicely (maybe 55-60 hp) above 4900 but was a good bit softer below that break over point.

I'm hoping for a bit broader torque curve sice I've deliberately under stalled the Rocky to keep it straight off the line. I'm hoping it picks up another 50hp by virtue of an another 500/600 rpm without killing much if any bottom end or middle. That's why I haven't altered the cam or intake. We'll see
