Guys was bored today watching the kids and was wondering what do you guys think is the max hp a sbc can produce without power adders? I am a back yard mechanic and i know some about engines,but i dont think you can get 700+hp out of a n/a engine. Has anybody seen or read about sbc engine able to produce 700 or more hp.

Bill Mitchell has some cool small blocks. NOT 700 hp but they run on the street and only cost $11k compared to what I am seeing numbers wise above.
454 small block 600hp (most likely more HP but they promise at least 600hp.

Kinda. They've been running SB2.2 blocks since '98 and they went to the R07 in '08. While the SB2.2 is loosely based on the old smallblock, they're nowhere near the same engine.
The new one is out (R07) and it's a complete departure from the old stuff.

It's first year out, it helped JJ to win his second cup championship against purpose built race block engines from Toyota and Dodge.
OT: I really used to hate redneck roundyrounding (NASCAR) until I realized how much of the technology we use today was developed there. Pretty much anybody with cash can build an 800hp engine. The thing that makes me scratch my head is that they can run for 500 miles WFO at 8 - 9 grand and live. And that's after how many miles of practice at nearly the same levels.
Your best chance of a 700hp N/A engine will be with an LS based powerplant, IMHO.
