ls build advise

[edwin]

I am currently building an 05 LS 4.8L engine to put into a 76 Camaro and I am using heads with the 243 casting # and an LS6 intake. Well last week I was given the lower portion of a supercharger off an 2010 CTS-V. Is it worth me scrapping the LS6 intake and using the supercharger instead. Is it worth the build. Any advise, opinion or guidance would be helpful. Thanks

The LSA blower manifold will not work with 243 heads. The LSA has square port heads, the 243 heads are cathedral ports.

Not only that, you can't put the Rect port heads on a small bore engine. OP, you might want to re-evaluate the build.

I saw someone has the rectangle port heads for the small bore motors. Can't remember who though.

Mast did have some but I don't believe they make them anymore.

I read on another forum that you can fit rectangle port heads on a small bore motor if you run smaller intake valves. Understand that I read that somewhere, I have no proof that it works.
