Looking to build a 501 A-headed engine for X275

Well looking to build a 501 A-headed motor to run in x-275 class. Already have the short block just looking for ideas on who to go to as far as heads or if anyone has any forsale? Looking to try to get around 1,000 hp if possible?

call lem he should be able to help you out! search the venders at the top of the home page!  

How competitive do you want to be? Local? National?

Cam and intake are important.  Headers need to be huge.  Carb is key too unless you want efi and then we could talk you through that if interested.

Well looking to try and run 4.70-4.60's with a 3,000 lb car. Got to still build headers and all. Most ppl in the class have 588 bbf but trying to squeeze all I can with what I have.

I usually deal with Kasse on cams. Anyone else recommended?

Call Tim at bullet cams

With a 4.500" crank? Just wondering what those builds consist of.

Meant 577. Your allowed up to a 588.

So are they building long stroke engines or are they shorter stroke with a bigger bore kinda like the NHRA pro stock engines?

I looked back on some of Bruno's posts, 2000 horse to be competitive!!!!

I doubt there are many if any 2000 hp engines in X. We build a lot of x stuff and I can tell you this. Plan on making over 1000 real horsepower on motor (1050 or more would be nice) and plan on a good nitrous program.

Both are running fast.

Haven't been able to get on here much lately due to my new job, but ive wanted to try X275 as well. Would more cubic inches benefit better results if one were starting out from scratch? Im into looking at doing a 545 set up. Whats your guys thoughts if you dont mind.

There ya' go....

Had a long conversation w/Jim Kuntz (Kuntz&Co.)@ Fe race. He just Dyno'd a Big bore short stroke 538 w/Aheads that made 1150hp w/800+ torque .Had a cast single 4,Didn't say what Carb or Gas was used.

1150  with 538  is 2.13 HP / Cu in

Not many even make claims in the low 2.0  or high 1.9's

Nice.  I am guessing there was a lot of cam
and that was a fairly high rpm motor.

  Impressed!
