average horsepower from a 526 kb olds

what kind a hp does a kb olds with 18 degree heads and a hi helix produce,i know all combos can be different but im looking at a few,thanks!

 

I've seen a conventional (dart 360) headed 540 make around 2000 so I would bet a Big Chief style motor could make 2100-2200. The problems that people have had in the past with that style set up is valve train. Back when more folks were running wedge stuff in Pro Mod there were issues with the rocker stands getting pulled off the heads, I would think that a one piece stand like sonny's makes would be a good fix.

 

Big Chiefs

I'd Estimate 2300 Is Possible, We Always Double Heli Coil The Exhaust Rockers Hole
