Default PI-heads+blower on stock bottome end??

Is it a good idea?? i am getting a stock bottom end while i build a stroker on the side.
i have a new set of pi heads and a 96 4/6 sohc bottom end. and a vortech supercharger running 10psi ithink it might be more. will it take it? or is it all in the tune?

I'd run it at 8psi, that's what I'm running and I'm right around the 400 hp mark on 93 with 11* total timing, with an air to air intercooler.

why ask for advice if you weren't planning on listening?

i was just seeing if some one has done it and had a anything good to say about it. the bottom end has 117k miles on it and i know it will not last but its worth a shot. your specs are something for me to shoot for and i thank you for that.

i just did the swap myself, v2 running 10 lbs. and did the pi swap on a non pi engine. I installed cometic 0.75 head gaskets to keep the compression ratio near stock.
