Congrats John on your new best!!!

His car is no feather weight, John has picked up almost 1 full second since switching to the KRE HP Heads from his old Street Performer Edelbrock heads.

What does it weigh?
8.9s are in reach for sure!

What port flow on the HP?

Way to go John.

Good job gman...glad you finally let Gil drive. ;)

Excellent! Congrats!

Congrats!!!!!!!!!

What is the story on the heads ? The E heads must have been pretty tame. Flow and mods on each ?

Aren't HP's 330 cfm out of the box?


GTO George

Thanks Everyone.

The car weighs 3500# with me in it.

The HP's flow 430cfm. There is still some tuning to do.

Damn..........nice!



GTO George

Nice! :thumbup:

Your shoulder must be better ?

congrats on the nice run

Nice ... your haulin'

Yes the shoulder is doing Ok. Lol. It took long enough.

Good job, John!

:)

That thing is moving. Can we get some info on the differences in heads and the build in general. Was the same cam used with both heads ? What was the cfm of the E heads ? 430cfm HP, so they are pretty serious.

John, Where u shifting that beast?

That's really moving! Good job with the combo

Congrats John! That thing is flying.

good job. congrats!

The old motor was a stock block filled to the water holes. The E Heads I bought from Jeff V. back in 2005 and the cam I bought from his engine builder Jerry Loan. The head flowed around 330 cfm. The new motor is a 535 MR1.

I was shifting at 7000 rpm. Going to try 7200. I was going thru the lights at 8000 rpm. I think I am going to put my 390 gears back in.

The can in the new motor is a 850 lift and its a 55mm.

What gear you running now?

430

You might want to look into your converter, seems to be slipping a lot

Damn that's hauling the mail!!

Great job John! That's hauling :D

Brian

I was thinking putting my 390's back in.

How do I check how much the convertor is slipping?

Take your rpm at the stripe and compare it to what the number is when you take mph, rear gear and tire height.

Brian

John, how much power did your engine make?

Brian

We put the motor on the dyno when the heads flowed 400 cfm and it made 872 hp and I think it was 770 ft lbs of tq.

145.31 x 4.30x 336/29.5 = actual rpm(7116)
I didn't know what tire your running i guessed at 29.5 and if right your slipping almost 900 rpms on top, if taller its worse even.

Going by Darby's numbers, that's 11% slippage.

Brian

Mph is crazy. Are you running High Ports?

the tire is 30" tall.

Yes I am running HP's.

The convertor I am running is ATI 8" 5000 Stall with anti balloon plates.

So slippage is worse than 11%

Brian

Nice job John , 8 sec just around the corner .

Grudge race Gman005 vs Kasparian :3gears::car: lol

Yea , maybe 2019 norwalk .

Thanks Mike.

I talked with Jeff Kauffman and ATI and they think it's the converter also.
