Reply to "302 intake conversion"

I've never done this, nor have I heard of it. Basically, the 302 intake is about 1-1/2" too narrow. So to use it on a 351C, you'll somehow have to carefully measure the exact gap you have, then fabricate thick 'filler' pieces of aluminum or phenolic plastic to fit between the heads and intake, with a gasket glued on each side of each spacer. The ports in the spacers should be cut to match the heads and the intake, but you can disregard the water passages. 2)- The 302 intake is 'wet' meaning it normally runs water through it with a thermostat under the outlet elbow. You get to unbolt or cut away all this 9depending on which intake you own) since the 351C uses a dry intake with the thermostat in the block. Besides, this stuff is about where the 351C distributor will be sitting. Finally, the front & rear edges of the 302 intake may need trimming or extending to fit around the distributor, and to seal the remains of the intake to the end-dams of the 351C block. It seems like a LOT of work, done only by poor but skillful fabricators. I'm not certain if its possible to make any of the intake bolts line up with the heads; new boltholes may need to be drilled & tapped to hold the assembly together, or some tricky design work with the port spacers might let extra bolts work. a TIG-welder may be needed.
