Man I hate to see you spend all that money switching over to a roller cam in quest as you say you would be happy with a .10 of a second. I have seen so many people unhappy with this upgrade. You could very well see nothing with a stock cast iron intake and factory exhaust manifolds. There are way easier upgrades that are cheaper too.


Could you share those FAST legal upgrades that would be worth .10?




It would help if those posting would give enough info when starting a post. I didn’t see this was a FAST engine type build till you mentioned it. Must be top secret. Lol.



I did say "all out stock appearing build". Car is being built to run in the SuperCar series, but besides that and FAST I'm unaware of what else that could mean.
