If I were a betting man, I would bet somewhere around the 310-320 mark.

320s.

Jesus, some of you are low. Bolt on stock cam cars dyno 300+ just cause he's a stalled auto doesn't mean he'll dyno that bad.

I'd be ashamed of 310 from a cammed lt1 no matter what.

Yes, you do realize that a small cam to a medium cam will only change about 10hp?

You do know that a large cam will only dyno 10 more than a medium cam?

10hp is more than you think... especially when you don't look at just peak and when a cam that dynos 10 more at peak is probably well more than that in other parts of the graph.


Besides that, I said 320s, meaning it could be as high as 329 or as low as only 10 hp more.

What were you looking for? 300-320 seems about right.

I was aiming for 350+ I know it is a smaller cam than most but I couldn't spin that short block past 6400 and I wanted a cam that would be on the downward slide around the same time. Stock heads don't stop flowing until around 6200 even with much larger cams. What do you guys think my limiting factor is?? I know factory heads are capable of more than 320 horse

Haha only you would say something like that. What da eff you gonna do with an LT1 car, put an LS1 in it. Just give it to me if it dont please you. I promise ill keep it an LT1 car. Haha

With your combo on a generous dyno you might get lucky and put down 345ish. I think thats a generous figure on an unported headed LT1 with a lunati stick. Get it down there and see. Tell us how it goes and post some #s. It might suprise us all who knows.

People with the CC503 don't even put down that much power on stock heads and that is a larger cam.
