American Kelzilla headers

Cobrafang · #1 05-13-2010, 07:17 AM

The car is back at Gary Jones from the fab shop where the headers were built. I had hoped a jig was built to help with follow work but that was not the case. Anyways I am very excited about the outcome. The next steps are to get the b-motor put back together and take the car to the exhaust shop to finish out that part of the project. The once the motor is done it and the exhaust system are headed to an engine dyno. Yea ha baby.

Eric please post the pictures I sent to you...cause I suck!

Primary lengths are between 35 and 36 inches. The diameter slips my mind. The engine and headers are headed to Atlanta to be dyno'd on Thursday...not sur when exactly it will get done...shop has lots of work. We are taking both the 650 and 750 carbs to make sure we fit the right one. I am very excited about seeing the results. I am also working on an A motor with very low hours...not gonna say more than that because the deal may not come through.

Frame clearance is great.

More to follow.

But I do have to think about a tranny. I am sure mine won't last too long even though I am way more gentle than eastman.

Awesome, enjoy the dyno day. Will be interested if you get much gain with 750. We tried this on the 5.0 and it didnt give us anything. May have been different on the 347 though.

I am also working on an "A" engine plan. Going to be overseas for a few months but have started planning. Will be interested to see what sort of combo you are working on.

Tom,

I told you those headers are junk you need to trash them and start over and tell me what can you put them in.

I see, I was wondering if you pulled the LS and went back to FMC.

ummmm. NO!

Ok. So I have an issue that must be run to ground with the engine builder/dyno guy in atl. The engine only made 280 hp and about the same torque. Peak hp was at about 5600 and peak toque was at 4700. Those rpms are what expected to see. The issue is around compression I believe. Since I don't know the chamber size in the heads I am going to have them cc'd. I am showing 110 psi. The is way too low. I am going to have a long talk with then engine dyno guy (who was not the builder) on Monday to chart the way ahead. I believe I need to get all the numbers from the head and intake combo. Then I need to figure out what I should be getting.

More to follow...this sounds all too familiar on this forum.

Also....you know it is not good when the engine dyno guy uses alpo in the same sentence as your engine!
