i was just wondering what kind of piston and sleeve and everything that is best, i want to keep the reliability as good as it is so i want the best...

can anyone tell me where i can find the parts?

also which one could be faster easier? i heard theyre not much different and a well built 426 is faster than a 440ex?

thanks

 

i was told the smaller bore rev quicker

 

has anyone out there gone to hetrick racing for their 425? im pretty sure im going to get that and porting and 41 fcr carb and heavy duty rod because of the picture on their site lol hetrick racing

also if anyone did have their ex done their did it keep its reliability? and does it overheat?, also should i buy an oversize oil tank?

thanks
