360 swirlport heads on a 318

[Brian Hood]

I found a hi mi (march of 91) 360 at a local u pick yard. Is there a way to tell if they are swirlport? It has a old TB injection system. If I put these heads on an older 318 will I have trouble adapting an Eddy manifold w a carb to it? If I use these type of heads will I get 10 or more hp on this or what would be a realistic expectation for a stock street motor?
Thanks! Brian

take the whole engine.......

91 360 should be a roller cammed LA engine...

the whole engine with 2 plug wires disconnected will make 10 hp more then the 318

if you are talking about the 302 casting heads I believe they only came on the 318

those would be 308 casting on the 91 360...and they are open chambers...


take the whole engine...LOL

The only difference between genni 360 heads and the 308's are a better short side radius on the exhaust port. You can do that to any 360 head, its the 302's that are "special". Look at both side by side.

Actually, the 360 intake port floor or 'ssr' changed though out the years, it's subtle.
