Sounds like nice engine. What were dyno results?

The # 5 run was just at 4800 rpm and it was at 488 T /360 HP. I was just after a few runs to make sure it's broke in and no problems so if I had some one install it for me we wouldn't have to do it more than once ! I didn't have plans of selling it I actually built it for my own use . I put all the new xtra performance parts in it for strength and durability . I'm sure for a few different parts installed it would be more HP/Tq. so it's built strong enough for additional improvements if desired ! If you can give me an email address I can send you the last sheet of dyno !

This 462 is complete with Q/jet/ New HT starter / New HAYES flex plate /PM for more info and pics . BALANCED MOST ALL OF THE PARTS ARE NEW !!!!!!!
