We're not talking a few thousandths lol, there is absolutely no reason to change axles or driveshaft. But that's not the point.

These engines have not been apart (well they probably have been by now, but not then). Part of that shows how well they are built from the performance parts catalogs in the first place, but it also shows that there is absolutely no way in the world they should be rated the same as the old 427.

Like I said BS that is the stock tune!

Well maybe you should ask Mr. Patterson if he was lying or if Competition Plus misquoted him.
