Big Block Conversion, do it again?

Absolutely, I'd do it again. As a matter of fact my current project (67 Barracuda convertible) will be getting the 440 that is sitting in the garage. This and my wife's GTS convertible (original 340 car that will always have a 340) may very well be the last cars I build for us, but you never know. The swap is not hard. You also don't need a bunch of expensive parts...
