Has anyone ever tried puting an LT1 intake manifold on vortec heads? I was thinking that the port design on the manifold "should" be the same as the vortecs.

 

It won't happen, read my FAQ.

 

Wow, alot of info there! So I take it the LT4 intakes are compatable with the high port heads (fast burn/vortec). Wouldn't the intake from caprices and impalla SS's be the same as these? I think I recall them using the modified ports.

 

You might be right. I am assuming you're talking about the L99 4.3 V-8. It is a little funky and I've seen pictures of them upside down looking at the ports and they look just like the LT4 ports. Again, this is only through pictures, no measuring.

 

I'd like to see this actually. For everything it's worth, it'd be a cheap injection manifold to run on a set of nice heads. I've generally seen them not run too high, and I bet it'd be cheaper than getting the SD intake and then parting a TPI together.
