The setup just does not have enough compression to run the cam and carb it has... Performance is okay and it can reach 12-13 mpg on longer trips, but just running around town, mileage is fairly poor. And it doesn't really make great power until 2500+ RPM's.
My thoughts were not to go back totally stock, just a more street friendly cam and converter package, an overdrive trans and maybe a quadrajet carb.
The current setup includes:
GMPP four bolt block (standard bore)
Scat 9000 3.75 crank
LT1 Rods (5.7")
Keith Black Hypereutectic Dished Pistons
Comp 280H small base circle cam (.480 lift, 231 duration at .050, 106 LSA)
Comp 1.6 ratio full roller rockers
GM 487X 75cc heads with mild cleanup, 2.02/1.6 stainless valves
Edelbrock Performer RPM intake
Speed Demon 750 vac. secondary choke, 1" aluminum spacer.
MSD billet distributor, 6AL box and Taylor wires.
Hedman long tube headers, 2.5" exhaust with H-pipe and Flowmaster 40's
TCI Turbo 400 transmission with full manual valvebody (forward pattern)
TCI 2500 RPM stall converter.
The rear end has 3.73 Richmond gears and a Detroit Locker.
Here is it's "plain tan wrapper..."
