Yep. .30 over (355) 2VR flat top pistons, dart heads 64cc. melling 22210 cam 70-80 LT1, 1.6 roller rockers, manley aluminum rods, stock intake with adaptor plate (yea I broke my intake swapping engines last time)edel-crock 600 carb, accel distributor, and hooker long tube headers followed by a 3in pipe no cat and ravin muffler. I pulled low to mid 13's last night on street tires pathetic 14's, 4695 ft above sea level so in good old florida no problem laying down 12's. T5, 3.42's and powertrax finishes the rest of the car.

kinda what i was thinking. what kinda mileage you seeing out of these "street" motors?
No times yet but high 12's should be attainable.
350,flat top pistons, Pro Action 200 cc heads, XE274 cam, Comp 1.6 roller tip rockers, RPM Airgap intake, 600 Edelbrock carb ( gotta upgrade), T5, 3.42 rear. Like I said, not there yet but should be in it.

Thanks for all the responses, your combo's are really encouraging.
Do you think my combo is capable of running near 12's. I have a
T5 with center force dual friction clutch, stock 3.73 posi rear, 350
with 10.5 to 1 compression, professionally ported Vortec 1.94-1.5
Manley Race-Fo valves, Edelbrock RPM Air-Gap and Holley 770 Street Avenger carb with K&N 14 inch open element. (Don't know if it's going to fit, haven't put the hood back on yet) My exhaust is
Hedman 1 5/8 hedders to two Flowmaster 40 series. My ignition is MSD cap, rotor, coil, module, and wires. My camshaft is the GMPP HOT CAM w/ .525/.525 218-228 on 112. I have stock
15 inch rims and will probably get Nitto V drag radials for the strip.
I know I will need to upgrade the suspension to really hook and
tuning is the key to how well it will run at the track, but I'm hoping for 12's.

Talk to Pony Killer. He's knocking on 11s with a vortec-headed 350 that's got a streetable cam in it. As far as I know, he drives it daily.

Do you think if I got a set of Vortec heads machined fro higher lift and a performer RPM vortec intake with a smaller cam I could make more power then what I have now and get better gas milage also?? I have to get the valve guides redone anyways so they are comin off so mayeb I can borrow the money from my pops for some vortecs.
