1966 273 Commando - Thoughts

As I am still making decisions about what to power my 67 Dart GT conv I am constantly looking at what is out there for sale. Came upon this and wondered if those with good experience would be able to offer opinions as to whether it might be a decent option. I have read good things about these engines. I know they may not have the torque of a 360 and I can get 350hp from this build fairly easily I think. Add a set of headers and a better distributor, couple of other things, but mostly leave as-is. I am not looking for a tire burning race car....just something to cruise around with that looks AND sounds nice, and have some get up and go when I want it to. With a change of gearing in the back end I think this might be an option. Plus a Commando, although not numbers matching, would be more period correct I think. The guy wants $6500 CAD for this setup...love to get some feedback, and I look forward to thoughts on this.

Thanks'

I'd put a 360 in it. Still looks like a stock engine, but the HP numbers are more attainable. For ignition, I'd go with an MSD ignition and distributor. Mild modifications (cam, pistons with higher compression ratio, Holley 750 (double pumper or vacuum secondaries) will be fun, without the hassle of a weekend warrior; tuning, tinkering. And it's still able to run in pump gas.
3.91 gears and you'd still be able to highway drive.
