Not to go against the grain but my build wound up with 14/1 forged Arias cause I got some good deals on here for the Pistons , cam , lifters and several other parts from a member that was getting out of the sport. Flirting With Disaster had sold him all the parts I believe . I was a little concerned at first but once I had it all together and running I can say I am very happy with the results . It's very responsive and pulls extremely hard . The only thing I notice is that the engine needs to come to operating temperature in order for it to run its best . It has a white smoke haze till it warms up a bit then it's clean . Tune 1 is clean driving thanks to Mark Broviak. I'm doing 3.42 gears in it in the next month or so to see if I can get it deeper into the 9s on fuel only . Best time to date was on Tune 4 spinning a bit out of the hole . Gentleman at FWD said the lower compression would allow for a better air charge .
