Now i'm seriously thinking about putting a cam in the car. I'm lost as to what i should go with for the longest time i wanted a trex cam because i loves the way it sounds but it just doesn't seem practical. been looking at texas speed and maybe thinking ms3 or ms4. I'm also starting to lean more toward trying the car out on the twisty roads more than the straight line track so i don't need anything huge. Last question i'll probably geting a cam package. Do i want single springs or dual valve springs whats the difference benefits between them?
