I'm re-doing my brother in laws Pro Street '69 Camaro... and had this motor built for him - using his blower and some parts I had laying around. It made 581 TQ @ 4500 and 624 HP @ 6300.... and idles like a stocker. Not bad for a pile of spare parts. I had the block and crank... and the Canfield 220 heads with T&D Machine shaft rockers. Roller cam... H beam rods - Mahle pistons.
