Default need you opinion..long post (sorry)

98 z28 with 327 block bored to a 350.stock rods,pistons, and vortech iron heads. 650 holley dp with AED rebuild kit. Also has a NX hitman kit jetted at 150 hp. fuel pressure is set at 7psi on carb. and 6psi for spray..sound right..

Any idea where the timing needs to be set at?I'm pretty sure it is at 32 deg +- 2 deg.It also has MSD retard chipped at 4 deg. for the spray.

This same motor was in a 89 firebird and ran 6.87 and now it won't get any better than 8.10's...this new car can't beat a 2.02-60ft.

any more help would be helpful.. this car is slower then the tow vech. help....and thanks as always.
