If it was more of a strip car with occaisional around town cruising then the 350 would be a more cost effective and simple route while remaining durable as well. Also the 350 has less rotating mass so that would help as well when it comes to shaving tenths.

I have a few th350s out there in street cars that run anywhere from 11s to 9.70s so they will definately hold up under power again if properly prepared.

Easy response:
mostly street=700
mostly strip=350
