That's impressive. Thanks for sharing. It makes me wonder what would change if I go with a smaller cam if I stay to the limit of 5500 RPM. There seems to be a lot left on the table if I use the 651 and only go to 5500 RPM.

if you really want a low rpm cruise install a cam from a 1996 chevy 3500 truck with a 454.

Just think how much he will he able to slow the blower down with a 204/209 480 lift cam. 30% underdrive making 8lbs boost. Will prob only be making 500hp, but it would pull a skier up prettt quick lol

Thanks I will keep that in mind!

681 cam with blower Dyno would be nice to see off of any engine.

Ya and use peanut port heads to top it off. Lol

This is a 540 with dart pro 1 345 heads with a 651 cam, 8/71 blowers no intercooler with 850 carbs.

Those are good numbers at the boost it's running. Intake temps are not bad either. Not much timing too. Thanks for showing.

you just have to buy the whole motor...

Actually there isn`t any movement on the whole thing complete I may be parting out ...sadly..

Those intake temps below the blower? you guys dyno in the arctic or what?
