hello fellow motorheads. i need some help. i have built several small block motors, but im going to build a big block for my 70 chevelle.what i need is to know if anyone has a really good street,drag combo for a big block. crank heads,cam, etc.i would like something to still run on pump gas but be pretty bad *** as well. so far i have a built turbo 350 trans with shift kit and a narrowed 9 inch rearend with 373 gears.also maybe what stall i need to be running with the motor.thanks alot guys if anyone has any info on this.it will be greatly appreciated. because when you go to a machine shop they kinda want to do alot more or dont even really want to talk with you.
