Re: How much HP?
The guy I bought my car back from had the 327 in it that I gave my Nephew that was made just like I mentioned and he said he had a 12.9 second, 1/4 mile strip slip from a South Cali. Drag Strip somewhere using NO more then a small set of real slicks!
Motor was a rebuilt, .040" over, 300hp/327 with a Holley 1850, 600cfm carb on a cheap aluminum adapter and a stock, cast-iron AFB intake, the Crane Came Dynamics 272/272 Energizer and a set of cheap 1.625" Hooker Headers and small blown-out, worn-out Turbo's! Heads were 1.94"/1.50" double-humps with a point distributor with a see-through cap!!
I figure she was right at 10 to 1 CR.
M-20, 3.31's too! BUT my car is an early, Dec. '66, '67 car so I figure it is LIGHT!!
AND I know it ran hard before I pulled it to make way for my Strong-Arm 406 SB so I had NO reason to doubt him!!
I am saying that a 327 can be made to run like a 12.9 second "scalded-dog" with not much done to it if it is up around a stock, 10 to 1 CR. to begin with!!
GM got the litte sucker just about dead-nuts right when they made the hi-po 327's!!
