Today i dynoed my Cam only LT1 motor before it goes up for sale this winter, The numbers seem to be normal for the mods, im sure it could be higher if i got the combo dyno tuned with a e-water pump and maybe some true duals but i have a 396 in the works so i looking forward to bigger and better things next spring.

my buddy dyno'd 347 to the wheels also with his own custom tune and no crazy things like electric water pump and what not. he thinks his springs are bad though, it fell flat at 6K

 

not bad with stock heads with no work

 

Not bad at all. Are you selling just the motor or the whole car?

 

Thanks, Im selling the Complete Long Block Minus a few things.

 

nice #'s cam only.

 

Man im dying to get my car to a track, I put down 391 rwhp and 376 tq on a mail order tune. I have the gm847 aswell but I am really happy to see such good times with your set up makes me look forward to running mine.

 

Why is it peaking at like 5500-5600??

 

heads are probably choking the cam up top. Nice #'s for the mods.

Nice. On an initial run, my GM847 heads/cam setup did 371/345 SAE with:
Clogged air filters
3" vacuum at WOT
11:1 AFR at 6500 RPM

I think it's a safe bet that it can break into 380's once I iron out those issues. Once school is out I'll do some more datalogging and get another baseline.

 

After it peaks the power pretty much stays flat until 6500 rpms so im shifting it at 6800.

 

Cool!
