with the tr220 do I need longer pushrods if so why do they sell them with 7.400 lenght pr. instead of 7.425 pr.

Get ahold of Thunder racing and ask them what the basecircle difference is between their cam and the stocker. I didnt check with my cam grinder and now im having a freaking valvetrain tick from hell!!! Its very annoying! When he gets back with me about the subject, Im probly going to be ordering my 7.425 inchers.

tr220 needs the 7.4". that's what i'm running and my valvetrain is as quiet as can be

Just go with the 7.4". Your valvetrain will run nice and quiet.
