305 TPI NEED TO GO A LIL FASTER

OK SO I GOT A 1991 FORMULA WITH A 305 ENGINE WAS WAY TO CLOGGED UP WITH NOT OIL SLUDGE BUT WITH OIL ROCKS

I KNOW OIL ROCKS YUP EXACTLY THATS WHAT WE SAW.....WELL AFTER WE TOUGHT ABOUT IT WE WENT AHEAD AND REPLACED IT WITH A ENGINE WE HAD FROM A WRECKED ENGINE FROM A 97 CHEVY TRUCK SO NOW ITS A MORE MODERN ENGINE STILL 305 BUT WITH VORTEC HEADS.

What casting number are those heads? You should be able to see it through the oil fill cap.

Re: 305 TPI NEED TO GO A LIL FASTER

Auto or manual?
Hell you want to go faster, swap out the gear in the rear end.

Auto 3.73
Manual 4.10

That's a no brain-er.
I have an 87 TA, I swapped to a 3.73, and I love it.
