624 HP Blown 383 on the Dyno - Lateral-g Forums

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.

How many lbs boost?

If those were your T&D shaft rockers laying around, I wish I knew you had had them!

Yes they have been laying 'round looking for a good use for 4 or more years now... however - they would not fit a standard set of heads - they were 450 offset arms for the big Canfields valves...

Dave -- You may or may not have read my post about it not being my first goat rodeo ---- and some comments I posted about a motors "rate of RPM"....
My 406 is done NASCAR style - Honda rod journal size - small rod end - with the reduction in reciprocating mass....

So check out the two dyno sheets comparing my longer arm 406 and the blown 383 - the FAR RIGHT column that shows RPM Rate of increase -- and compare it against the 383's.....

I read something somewhere about your wishing to use some tools... or something like that.

Did not read about rate of rpm... but am interested? Which thread if you don't mind? I didn't know your 406 was built in such badassedness style.
