is it smaller than stock? if so i would want to use a longer pushrod correct? anyone have the formula or just an answer as to what pushrods to use? it will be with stock rockers and lifters if that makes any diff.

 

I used 7.425
Base circle was 1.453 or .097 smaller than stock.

 

does that give u a quiet drivetrain? this is a dd and the less wear and tear and noise the better.

 

Quieter than 7.40's that is for sure.

 

well would i be better off with the 7.425 or the 7.45? my car is very low mileage and i dont want to ruin anything just yet.

 

I would say the 7.425's.

 

Blah I have 7.4's with a TSP Torquer V.2. Do I need to buy different pushrods or will I be ok?

 

HolyShiznit are those N2O numbers? It would take up any slack that you might have, but 7.425's would work. What are your heasd like? mill wise...

 

Yes those are N20 numbers, 150 wet NX shot with a VaraRam, that's the only mods done to the car period.

Heads are just stock heads that happen to have the dual valvesprings and retainers that I needed to run the cam, so I bought them for 300 shipped.
