Good luck with the clutchless s/c pulley if you can make one with no loss in driveability id be all over it. Nothing sucks like a vette pulling up next to you and theres no time to downshift so you punch it and have to wait a half second for power.

Also, build a good set of tubular headers that fits PROPERLY for less than a G.

If you built an air to air fmic with proven drops and sustained drops in IAT's id be interested.

As far an exhaust and all the parts i just mentioned dyno results are an absolute must. Nothing like building a $1500 exhaust to discover it makes more noise but no more power, not speaking from experiance or anything.
