Does this guy know what he's talking about?

I watched that video yesterday, confirmed my reservations about messing with the slant-6... head ports/valves too small, severely undersquare/tiny bore, heavy rotating assembly. I liked what he said regarding the 170ci version, if I did own a slant-6 car at some point it would be an early A with a 170 and 4-speed manual with some minor upgrades.

Or if one landed in my lap I would cut my teeth building my first home-fabbed turbo setup. Only real "straightforward" way to make decent power with those engines; going N/A basically takes re-engineering the whole thing IMO.

I really wish Mopar did the same with the slant that they did with the AMC/Jeep 4.0L, that engine got a high-flow head and was oversquare from the factory and can be stroked up to 4.6L+ with a 4.2/258 crank. Not that I would try putting one in an A-body but I love the one in my Cherokee and will be doing a full performance rebuild at some point. Would also be neat to build a hot one to drop in an old Rambler.
