It just never ends. I just got my 350 running great and now I need a 427 and new AFR heads. I should start smoking crack so I don't have money for the Vette.

The plan it to build the best possible combo for my plans. Quality and performance are important, with quality coming first.
Not sure exactly which way I will go. If I put a cage in the clone, I may target 10.50.
AFR is not my only consideration.

I have flowed a handfull of the raised runner All Pro heads (in the 245 cc range)....most come in the 340-345 range on my bench @ .800 lift....very close to what a production AFR 235 is going right now. I think your flownumbers look a bit optimistic honestly even for a raised runner head but we are comparing apples and oranges anyway.

We are extremely excited about the release of this product and Im sure much like the other Eliminators, once real world results finally start rolling out, you guys wont be disappointed.

My guess is Jim Barth (TPI421Vette) will be one of the first to try a set so you guys shouldn't have to wait very long for independent feedback.

Been watching for them on a couple of sites...should be a very good Head for the bigger or more "serious" motors.

Delta T...that sounds like at least a 7 - 800 HP motor in the works...

These heads will want a big big inch motor/big bore and some rpms. I would think a 420" small block is bare minimum for these heads and intent to turn 6500 rpm peak power+. If anyone has the big dart blocks for over 434 inches could use this head nicely.

Not quite the street car build head I would say. AFR 210's will do most anything you could want out of a streetable setup and fit all motors from 383 to 434. There are guys running mid high 10's on fairly mild setups with AFR 195's on 406" + motors. I cant imagine what a big solid roller and 434 will do with 235cc heads

I am targeting 800-900rwhp on no more than 14# of boost on pump 91 with alky injection. The 434/AFR 235/YSi/World manifold/1 7/8" longtubes will replace the 383/E-tec 200/T-trim/Holley manifold/1 3/4" longtube combo shown here:

http://home.mindspring.com/~jim_fisk...s_side_med.jpg

The current homemade (all brackets, tubing, etc.) combo put down 632rwhp at 11.87# of boost.
