Rob,
Dennis' motor was run with manifolds not headers. The next LS6 motor they did for me was assembled identically but used headers instead and it was 492 hp if I recall correctly. So far we have built three of these and all were between 475 and 492 hp. The builder still owes me a case of beer as he said this engine would never break 450 hp with manifolds (and I said it would) and he has done it three times now.

Peak horsepower was 475.1 at 6100 rpm and torque was 482.9 at 3700. Average was 462.4 hp, 393.8 trq at 4500 rpm. They made a total of 7 pulls.

For anyone with access to a dyno, it is one of the better things I have done. They set the carb, timing, valves, etc, make an average of 7 pulls after breaking in the engine and carry it live on the internet so guys like Mark Mitchell could watch his engine dyno run live from California. All this for $250!!!! All I have to do is drop it in and run with it.

Dennis..................YOU DID WHAT???????????? Just kidding, they were meant to be driven. Besides, if I know you, you drove it for 1/2 hour and will clean it for 4 hours! [img]<<GRAEMLIN_URL>>/wink.gif[/img]
