mid to high 300's...

 

I say 410-420 rwhp and about 390-400 rwtq.

 

There are several important things to consider, like flow numbers on the heads, compression ratio, tuning and exhaust. If done right you could see as much as 450+rwhp.

 

I'd guess in the low to mid 4's assuming you have whats not listed.....headers, converter...etc.

 

And if it's not enough for you, with that bottom end you can spray another 175 RWHP easily!
