Guys,
I have a 96 Impala SS. The motor dropped a valve at 72,000 putting a large hole in a piston. I am rebuilding as we speak. Here are the specs:

355 ci LT1
Agistino ported iron heads with 2.05/160 valves, 274cfm intake and 201 exhaust at .600 lift
Scat cast crank
stock rods
JE forged pistons
ARP rod and main bolts (2 bolt main)
R series CC lifters
Trick Flow chromemolly pushrods
CC 1.6 pro mags
CC 230/236 XE cam
Yank 3500 stall
GM 4.10's
built 4L65E with transgo shift kit
27/10.5/15 /ETstreets
Rememmber this pig weighs 4400 lbs. What do you guys think it will run all motor? Do plan to run a 150 shot down the road. Tell me what you think.
HVY SS

 

Mid to high 12s on the motor alone.

 

Yea i was going to say high 12's. I watched a guy at the track with a impalla go 12.0@112...not sure on the mph but it was right around there. He was running a 200 shot though....on stock internals... . He had pretty much all the bolt ons and heads/cam as well. I dont know the specs on the cam. I think he was running drag radials too. Fast car...
