305 auto w/ the peanut cam butt stock I would guess mid to low 15's depending on the mileage & how well kept it's been "oil changes, spark plugs, etc."
And as for the whole treat it like an LO3 I wouldn't know but the basic mods like exaust, headers etc. are always a must.

as far as the rear goes im not sure what gear it has but it does leave two black marks unlike my RS that leaves one dorky one
its a mass air car with the old style bolt heads on it
if it runs 15.5s that would be cool cause it wouldnt take much i wouldnt think to put it on down into the 14s maybe even 13s
the car has 113,000 on it all original car, the guy i got it from took fairly good care of it as far as maintanance goes but the rest of the car is so/so
thnx again guys and ill keep posting the build up

Hmm, how are you hooking up? I'm not too great on TPI, but with those mods and hp #, you should be in the 14's. Throw on some SFC, better LCA and better torque arm and it should help.
