Shouldn't be a problem. I know plenty of guys pushing 150 shots repeatedly on bone stock 5.0L shortblocks in fox body cars.

stock 5.0 motors have forged pistons, stronger than hyperetic pistons. 5.0's will easily handle a 150hp shot all day. you better get another opinion and be sure. ------------------ 67 coupe, 650dp and rpm intake on 5.0 with afr 165 heads, 4 speed, 4.11's.....best so far is [email protected] in 1/8 mile with 1.79 60ft. time.

If the top ring doesn't have at least .030+ end gap on that KB piston I wouldn't spray it at all. I personally wouldn't use a hyper piston in anything I planned on spraying, I've seen them lift the top without running the jug....they hold a ton of heat.------------------ Butch 460 powered 1967 Comet Cyclone 10.271 @ 130.069 Butcher's Home Page "Friends don't let friends drive Chevys"
