I am going to build a Chevy 400 small block for my 1970 C-10 2wd. I am using vortec heads, 64cc. Does anyone know of a good piston to use , so the commpression want be to high? I want to be able to run med grade gas in the vehicle. Maybe a piston with 9:1 compression. If anyone could help I would be very greatful.

Re: Engine Help
Contact Jegs or Summit and they can tell you the right pistons to use. Dont forget to drill the steam holes in the heads. Are you using a 400 rod or 350 rod?

You'll likely want hyperutectic pistons. Cast pistons are false economy; they're a bit cheaper but not nearly as durable. Forged are more than twice the price and not needed unless you're planning on a power-adder like NOS or a blower - or you're looking for more than about 1.2 HP/CID Manimal nailed the key questions; remember that you can't buy pistons until you know the bore size. Unless you're building something hot, you'll find the Sealed Power or Northern Auto Parts rebuild kits are a really great deal. Try to find one with a standard volume pump; high-volume pumps just waste power. Have fun and let us know how it's going. Pictures are always great ![]() |
