Hello all,

I've seen a 600cfm Holley four barrel for sale near me, but just wanted to check something. I don't have access to my car til the weekend, so can't check whether the stock inlet manifold is square or spread bore. Anyone know? Also, I assume a 600 vacuum secondary carb should be fine for a stock 350 motor?

Stock manifold for your car is a spread bore.

 

You will need a base adapter and a throttle cable bracket to get all the gas pedal that opens the carb completely.

 

Thanks for that guys, probably not worth doing by the time I've bought the extra parts.
