Jeff, with all due respect:

Would you justify your HP increase knowing the throttle body, upper and lower plenums as well as runners are exactly same for both the 305 and 350.
Essentially the same carburetor. Don't actually know but common sense tells me the carb and intake found on a 305 might be smaller than that found on a 350.

How does the additional 45 cu. in. factor in when both have approximately the same available airflow to the intake runner and valve.
Then also factor in that the intake system is better matched to the 305.

It may need some HP but 30 plus??
