will a 273 intake fit a 318?

Yep is to re-drill and offeset the angle, dont dont get crazy only so much HP in a 273 do to small bore size etc. Yes you can make it run, been there done that, but for the $$ a 360 or 318 is a no brainer..

So this is a good point, I would redrill too!

I agree with djwhog that to use the bigger engines are a no brainer. I've seen these manifolds in the past, but knew no one to run them.
But then I see a 2 X 4 set up on a 283 Corvette on Barrett-Jackson and ask myself how come we don't see more 2 X 4 273's. It would have the old school kool factor.
