Ran a best et of 9.70 at 72 mph. Also ran a couple 9.80 and 9.90's. Interestingly enough 72 mph was the same on all the passes.

390 crank and rods, trw forged pistons (10:1 aprox)
Cast iron 390 heads w/ 2.09 1.66 Stainless valves
Comp XE274H
PRW Roller Rockers
Performer RPM intake
Edelbrock 1411 750cfm
Longtube headers

TCI Streetfighter C6 with the TCI Saturday Night Special converter

2 1/4" exhaust all the way back through Flowmaster 40 series mufflers.
Stock DuraSpark 2 ignition system

I'd like to get closer to 9.5 et in the 1/8 mile. Any suggestions?? The 2 1/4 exhaust is going to be upgraded to 2 1/2 or 3" soon. Will I see any noticable gains? Is the 2 1/4 holding me back? Any other ideas how i can squeeze a few more tenths???
