I've got a heads / cam / bolt-ons LT1 with a stock bottom end. Currently puts down 366 rwhp with a Comp XE 224/230. If I were to throw a blower on the car, what kind of power numbers could I expect?

Thanks.

 

What heads you got?

And, how much boost you lookin at?

 

I'm running the Combination Motorsports "Stage II" package. I don't have flow numbers for it, but it's a 2.02 / 1.6 valve setup, 3 angle valve job, etc etc.

As far as boost, I'm not sure. All I've read is that ring landings start to give out after 6 psi.

It's an issue of how many thousands I'd have to throw into the powertrain to make the blower "worth it". You can get 425 rwhp in an LT1 with a monster cam at a small sacrifice to driveability. If that's what I can expect with 6 psi, then $2500-$4000 on a blower is a waste of money. Now if an additional $2500 into a well-planned 355 setup can net, say, ~570 rwhp, then your $5K investment is starting to pay off by doubling the power output the car had before.
