I am wondering rather not a 750 vacuum secondary will be to big for my motor. The 600 we had on it is just to small, and for the price there is no in between. I am on a strict high school budget.
Motor specs
355, cam is 508 lift 313 duration. Heads are 327 double hump heads 64cc. Flat top pistons, Should be close to 9:5 compression.. Supposed to have a close to stock crank and rods. It is bore .30 over. Edelbrock Torker II intake. Arp rockers, its a Hydralic setup. The motor will ping like crazy with a 600, if it isnt getting premium fuel. I''ve had the motor rev to a little over 6k, with out a sweat. We are running a turbo 400 with 4.11 rear gears. It has black jack heads, straight back to flowmasters. What i believe to be a classic 40 series.
Sounds ok? The 600 is going back tomorrow, and a 750 will probably go in its place...
How it sits.
