I have a Champion 4 core off Ebay under 400 bucks seems to work so far almost a yr. Its big well made from what I see all welded no epoxy. It can idle under 190 all day with focus dual fans. When I cuise at 75 2500 rom it creeps up to 200-210

257
Just a thought arnt pro gears 35 spline on the pinion? You might need to order a new pinion yoke also.

258
Yes it was balanced 13lb aluminum flywheel, pressure plate and all.  I sold all the SCJ stuff hatchett, flywheel, crank and the rods.

259
I have the eagle 4.25 crank and I used a zero balance flywheel. I bought the flywheel from Brent.

260
Yes it will I have hydroboost and it stops on a dime, I did get a rebuilt pump  though.

I plan on doing just that at Cecil dragstrip on the 29Th Barry. I find it hard to believe there is 50 hp there or even 30 hp. If it was a stock exhaust maybe, but 2 1/2 ID and Flowmasters shouldn't be that restrictive. I agree the Flows rant strait thru design but certainly not like the original cross flow. What is the muffler of choice for the street racer these days. While I was at the dyno there was a Corbra and it had spintechs definitely not getting those. I might as well have just pipe they crackle to much. Jay what cam would you recommend? Also the Streetmaster should support 640hp according to you guys so it  would be worth it to have JDC look at it I think. In the meantime I'm going to try and look at the back pressure scientifically before I go. I'm tired of hit or miss should be an easy test.

Wow guys great offers.Joe I appreciate the offer and will pay whatever the costs are and your time. When I built this engine I was expecting like 550hp so you can see why I"m a little disappointed. If I need a new manifold so be it. I was planning on 3" Magnaflows anyway. Is there a better muffler? Strait thru bullet? I like to drive it and want to hear myself think also. I'm going to Cecil County speedway in two weeks. I think I will make a few passes after I jet up a bit to 12:1 a/f. Then remove the shaker top, then the air cleaner altogether. Finally the exhaust that should be some good data. I'm working this weekend so I"ll look around work for a usable gauge I work at a national lab. If can inject a super collider with heavy ions I'm sure I can measure some back pressure and get back to you. I would really like to solve this dilema.

I bought them from Barry R that was the advertised flow for his CNC ported Edelbrocks Pro port I belive they are called. ON the FE forum Werby says im leaving 50hp on the table with that exhaust. To me thats alot of hp.I be happy spendsing 700 for the magnaflow 3 and getting 50hp. That sounds to good to be true.

Jay I"ll have to look up the cam specs. I am at work and been doing a ton of OT so it may take a while. One was Comp 284H extreme on a .040 428 with ported heads that flowed 278 in. The other cam was basically a stock Gt type cam by speed pro on a.040 428. I lost the card on that long ago. The cam I have in this stroker is at home, its a custom cam for a local builder that does alot of Cobra stuff. He also used to race FE's back in the day has since moved onto clevelands.

I agree on that et that's the disappointing part. What would you consider substantial horsepower? I'm starting to believe its the intake that's 3 different cams 2 hydraulic one solid,3  sets of heads stock gt ported gt and now Edelbrock. 2 differant strokes 3 differant carbs  and it never pulls really hard over 5500. The only common thing is the intake. I posted the dyno vid on Youtube    http://www.youtube.com/watch?v=DV3FmQgkLmQ

Yes Jay chassis dyno, thru mufflers, 850 dbl pumper. timing locked at 38 deg. I also have a mechanical fuel pump and Stainless steel flex fan if that matters. It pulled till good till 5400 then rolled off. The exhaust is 2 1/2 I corrected the original post. I appreciate your help.
