Thread: need a little help from those with experience on sbc drag motor.

Tweet

Going with a aluminum block is definitely the way to go but thats way over my budget at this time.Unless I find a great deal! So what I am getting is that I should go for a 400 or bigger sbc, something like a 421-434,right? Also I know the nitrous is hard on parts ,like any power adder,so I am only going to use it with one of those progressive controllers. What length rods should I use or stay away from ?
