Ignition or Piston??

[raptorman22]

I dont know what to get a JE high compression piston 10.75:1 or a Dynatek Programable Ignition. What do u guys think i should get and would be more proformance help? thanks

I'd go for a piston and cam first, the dyna ignition makes a much bigger difference once you get some engine work done first.

deff the motor work first

yes go for the 10.25 compression piston. The piston will give you more torque!

Do i have to bore with the 10.25 because i dont want to bore. where can i buy it?

Don't have to bore it as long as you get the stock piston size, but you should definetly hone the cylinder.

Alright Thanks

That's if your cylinder has very little wear though. You will definately want some stiffer springs and a cam before the ignition, you'll float the valves.
