Here's the thing; with the head on the 225, being the same unit that was designed for the little 170, it's just extremely hard to get a lot of power out of that motor, but not very hard to slip into the 14's with it.
A 14-second car is not slow... Hell, the bulk of the "musclecars" in the '60s would only run mid 14's... I'm talking 389/400 GTO's, 383 Road Runners, 1966 390 Fairlane GTA's and 271hp hi-po 289 Mustangs....
You can have a LOT of fun with a 14-second car on the street.
Just be aware that some thoroughly modern imports with their 3.5-liter V-6s are that fast... cars like the Toyota Camry, Honda Accord, and the Nissan Altima... are all, low-14-second/100mph runners according to the road tests I read in the major magazines. Amazing...
But if you can be happy with mid-90mph/14-second performance, a 225 slant, naturally aspirated, can be the ticket in a 3,200-pound A-Body.. It's fully attainable and no turbo is needed...
If, at a later date, you want to go faster/quicker, forced induction is always there for you to try.
