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

Big inch built for torque, not only less parts breakage but IMO much easier to make the car consistent. With that said, the nitrous will negate the less parts breakage point.... Go shopping for a used aluminum big block and a good machine shop to do the block work. Build a ton of torque, leave the bottle in the shop. Probably save you money in the long run.

The first rule of racing (any form of it) is that before you can finish first, you must first finish!!!!!

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 ?
