Mike, I bought my GS in 1980, It's an original 72 455 GS car and I have always ran it as a 72 with the 455 and 350. As far as the other make's go Chevy close/Mopar not so close!

Chris, This is a good question, I have turned the motor around 6400 before an the car ran 11.40-50's and now with a new cam an other changes the car runs 11.20-30's at 6100-6200. I guess my best reason for less RPM : 1000gram piston/pin,3.900 stroke, valve train failure, Buick is known for it's torque(an taking grandma to church on sunday)lol plus more RPM does not always mean more Hp?? I guess?

Don, When I started bracket racing in 1977 then Stock in 78 with my 67 Buick 400 GS, I bought alot of parts from KenneBell and got some good information and some not so good!
