265 Stocker hp?

Dick Butler · 02-17-2016, 03:13 PM

Has anyone tried a truly built 55 or 56 265 for a stocker lately? I wondered how the HP output with todays rulebook has become. Talking about a 4 barrel motor.
Noticed hp difference is in the rules so 55 might be better .

I could be wrong but I'm sure the 55 265 has no valve reliefs making piston to valve a challenge with much over a stock profile camshaft.

I"ve raced a 55 Chevy 2Dr HDTP in Q/SA since NHRA brought back the early cars years ago. Bob, your right, the pistons have no valve reliefs and the cam lift is .334 on both the intake and exhaust. Not much room to play with. I've run close to .65 under with the car. I put in for horsepower reduction last year, but I blew it. I thought the limit was .65 under but it was really .55 under, so I didn't get it. Maybe this year.
