Anyone adapt hi-performance 340 manifolds to their 71-74 Bbody?

I may be in the near future, but I'm not sure there is much to adapt. They don't take up much more room than the 318 log style. The outlets are in a bit of a different location so you may need to change where exhaust flange hooks up. Headers are probably a better value unless you have a set laying around (thus why I might be using them). Those pieces on E-bay are, how should I say it.. over priced? It appears they are missing the cross over thermostat valve as well so you would need to find that or plug the hole where the valve goes.

Yeah they bolt right in no problem s your exhaust flange will need moving /angleing
