I'd be more apt to use the 700R4. You need help getting power to the tires because of the rather small displacement.
Don't get me wrong, I think the 327 is a fantastic motor and have long thought that the bore to stroke ratio on it is optimum for an internal combustion motor. It just hit the "sweet spot" in my opinion. Chevy claimed 375 hp from the little jewel back in the 60's, STOCK from the factory with technology which is now 40 years old.
As I posted on another thread concerning the 700R4, using a rear gear somewhere around 3.70:1 will give a very low first gear to get the vehicle moving (11.32:1 first gear final drive ratio) and a 2.59:1 top gear final drive ratio.
As far as more poop for the motor, I'd concentrate on the cylinder heads, keeping the intake runner size around 160-170cc's for street use. Research to find heads that flow the best at 0.400" valve lift at that runner size.
Don't make a camshaft selection until you get the final static compression ratio sorted out and determine the rpm range you will operate the motor in.
