I just purchased a 70 gto that has a rebuilt 455 bored 30 over 462, He put on the engine a 850 holley double pumper, a torker ii cam and intake with ARP rod bolts and forged pistons.
This is my first car and so just learning about everything.
My question is everywhere I read even with the stock 455 it is recommended a 12 bolt rear. I dont know what this motor dyno'd but got a good price on the car and all the sheet metal was done which helps me as I am not the best welder.
Could I upgrade to a 12 bolt in the future if I am not doing burnouts or dropping it etc. Also is this this just going to waste fuel? Is a 850 double pumper truely needed?
TWE
