602 or 604.... Need advice.. New Racer?

[ElliottAugust]

I recently bought a complete roller 2007 Lazer late model.. I will be runnning the car as a crate late...
I have a 602 currently from another form of racing but im hesitant on using it..
I am wondering just how competitive it really will be...
I will use msd and plan on buying a crate built carb...

Will i be wasting my time with the 602 or should i just buy a 604??

Any advice is appreciated

Thank you

I think it all depends on how much work has been done to the "crate" engines used by your competition.
