Rebuilt 318 High Performance

I will also sell the parts from this engine separately. I will sell the entire short block including the timing cover, water pump, harmonic balancer, oil pan and motor mounts for $1350. I will sell the cylinder heads complete including the rocker shafts and Proform rocker arms and the Smith Brothers pushrods for $650. That leaves the Edelbrock Street master intake manifold for $75 and the electronic distributor with the MSD plug wires for $50.
would the intake manifold be a straight swap to a '67 273? my 273 has a 2bbl and I want to swap for a 4bbl, do you have a carb for the intake as well and what size if you do?
