060 over 1973 454, Bowtie heads, RPM intake, 750 Holley, Comp Cams 284 Xtreme Energy, Harland Sharp rockers, Bowtie valve covers, new balancer and flexplate, have a resurfaced flywheel too. Rotating assembly all balanced. Similiar motor was built and that made 540 horse. Motor runs great, just needs a good carb. 750 on it now works, but is stock, so motor isn't running up to it's full potential. I have a new set of headers for a truck, and a new Comp Cams Xtrme 268, little calmer than the current one. I can ship or maybe deliver.
