Going to pull my 389 Street/strip motor out of my 65 and replace it with a tamer/cooler running 455. Any ideas for crate motor builders? I have Butler Performance on my list, but Tennessee is a long way from Phoenix...maybe something closer? Will sell the outgoing 389 runs good/has dual 4 barrels but oiling spark plugs in cylinders 6 and 8 every two to three hundred miles. No smoke yet however.
