406 vs 421 or 434
I am ordering a 406-434 from Nyes. Was wondering how much I will lose out on if I get a 406 instead of a 421 or 434. I bracket race a dragster, want to go about 7.90. Car weighs about 1500 with driver. I run Brodix 11x heads so I need a different piston to go with the heads. JE make a piston for a 406 and 11x heads but not for a 421 or 434. Custom pistons would have to be ordered for 421 or bigger. That would take 3-4 weeks. The 406 is cheaper and quicker to get than the others, will I regret not waiting and spending more???
