    Question SBC rx 7 build up?

     



    i have a 84 rx 7 that we are planning on swapping a SBC into with a grany's motorsport swap kit. the car only weighs around 2336 pounds. i am wanting to see what you guys recommend for a engine build up for what i want. i love torque but any SBC will have enough to launch this car. what i am looking for is a build up that will let me run to 6000 - 6500 rpms when racing and is high on horsepower. the highest compression i am going to go is 9 to 1 because we think we might go to forced induction later on. what set up would you guys run with?

    i've never heard of anyone that builds 302 crate motors, seems to me your best bet would be to get a 327, or 350 block, and have you a crank made to fit it, but don't take that to heart, because i really don't know right off hand
