Can I replace my 2-barrel carb with a 4-barrel? Currently have a 1964.5 260 V8 engine. Not a bit unclear online whether I can do that, but if so, what my options might be. Thanks all
the nice thing is that anything that fits the 289/302/5.0 also fits the 260, and the rarer 221 SBFs as well. so go ahead and put a four barrel carb on that 260.
They were available with a 4 barrel from the factory. I’d stick with no more then about 400 cfm along with dual exhaust
good advice, i would also add to use either an edelbrock performer or a weiand action plus intake, since they were made for stock and mild engines.
as for a carb, holley make a nice 390cfm carb that would be just about perfect for a stock 260, the autolite 480cfm carb and the edeelbrock 500cfm performer carbs are also just right for this engine.
if you plan to use aftermarket heads on this motor, the AFR165s are the perfect choice, along with a small tube header, say a 1 1/2" primary tube, but no bigger than 1 5/8".
for a cam if you go that far i suggest the comp cams h260he grind. good power, not too big, and perfect for the street.
