It's not the most powerful version of a 347, but it does pass emissions. This combo idles well, effiiciently pulls to 6k and will hit the 6250 rev limiter very easily. The torque curve is excellent too. If I were to do it again, the only thing I might change is the heads to AFR 185's.

Not having to fuss with emissions, a more aggressive cam and head combo will do a lot for the power numbers.

325 RWHP is a great number. Probably some room to get more with a little change here or there.... your red line seems a little low, but maybe a limit of the EFI system.

You will not be able to bolt on a blower. Your compression ratio will be too high with the flat top pistons. Your probably bewteen 10.0 to 11.5 right now.

I think you've got me confused with someone else. I'm not interested in a blower on this combo...just sharing what I did with the original poster.

If I were to go power adder, my preference would be a single turbo anyway...and the whole shortblock would require some beefing up.
