It is really all relative to what equipment you have in on and behind the 350.
I think you went the wrong direction, the 327 and 350 have the same bore and block actually, the crank in the 327 has a 1/4" shorter stroke than a 350 so you will loose some torque compared to the 350. You can use a 400 crank with a 1/4" more stroke than the 350 crank, then you GOT torque!

When it comes to towing, I'm more a fan of torque than hp. That's the plan for the 318 poly build anyway. I'd favor something like a 383 build. Without much trouble, you can get your 400 hp and have plenty of torque.

If the Blazer had the 3.42 rear, I wouldn't suprised if it got hot pulling grades. And if you were running an auto transmission and towing in OD, I wouldn't be suprised either.

There are many factors that go into towing. Engine size is just one.
