Power Gain On A Stroked Motor?

imported_Gt_Jay · January 9th, 2008, 04:30 AM

hey guys what is the hp gain when you stroke a 302 to a 331?

JayVee · January 9th, 2008, 05:59 AM

...347's are approx. 340-350RWHP (mine at 347RWHP) and 331's just under that depending on what formula bolts and tricks u may add to the cause...LOL! APPROX.325-330'ish I would say...

well when adding cubic inches its about 1.5hp per ci...and when going 29ci you'll get about 45hp so over 302...and 347 gets about 60hp

Only a dyno can accurately determine this.
