Found a small block 350. Its out of a 89 chevy truck and the guy wants 100 bucks for it. It is fuel injected. How hard will it be to change it from efi to carb? What will i have to change? Thanks.

any basic small block 12 bolt intake will fit, however, the 87 and up heads 4 center intake bolts are at a different angle, so the intake must be drilled for the new angle if it`s a 86 and earlier intake, a machine shop can handle this job with ease, everything else is a basic bolt on.

What if i was to put heads on it from an earlier carbureted engine or aftermarket vortec heads. Couldnt i fit the intake on with no problem?

Vortec heads aren`t aftermarket, there factory GM heads, the Vortecs require a vortec intake which has a straight up right 8 bolt pattern, I do not recommed having a older intake drilled for use on vortec heads. as for the older heads, they`ll bolt right on the 1989 block.

WELL I WOULD PREFER TO NOT EVEN CHANGE THE HEADS RIGHT NOW BUT I DONT REALLY LIKE THE IDEA OF DRILLING THE INTAKE TO MAKE IT FIT. ANY INTAKES THAT WOULD BOLT ON WITH NO DRILLING OR MODIFYING?

edelbrock makes a bolt on intake to fit the tbi heads as well as the vortec heads.

OK THATS EXACTLY WHAT I WAS LOOKING FOR. THANKS

And you need to check the Fuel pump mounting most of the fuel-injection blocks are not drilled, you will need a electric pump.

If youre on a tight budget GM makes a carebureted intake for TBI heads too. Cruise around the bone yard you might find one.

WELL IM GOING TO BE PUTTING THIS ENGINE IN AN S10 SO IM PLANNING ON BUYING ALL NEW FUEL PUMP AND ALL THE OTHER ACCESSORIES. THANKS FOR INFO
