882 heads are 76cc combustion chambers, so when bolted onto a 327 with stock-type pistons and piston deck height, even with a steel shim gasket, the static compression ratio will be in the range of 8.00:1 (I did the math and found 7.99:1). Using any kind of performance camshaft with 8.00:1 static compression ratio and a 3.08:1 rear gear is gonna be a big disappointment to you in my opinion. What the motor needs is a bone-stock cam with 0.050" duration under 200.

You be lucky if it's going to produce power. With low compression and 3.08 gears is like a 400lb person riding on a tricycle. No go!

Sell the 327 build a 383 or a 406. You will be ahead of the game.
BTW: Get gears like 390 or 410.

No matter what you do to the motor/trans, you will need gears, so you may as well pull the diff out of the truck and start there. Everyone should begin at the rear of the vehicle. Gears first.

Focus on the gears and get overdrive tranny. Install the carb and intake on the 327. Long tube small dia. tube headers will help the low end.

Vortec heads, a 262Hyd cam and the requisite Vortec manifold.

If you want to go with a stick, the T5 conversion I mentioned before is fine, it'll be over 2grand unless you build the trans yourself from cores. You'll need V8 Camaro or Firebird guts, with an S10 T5 tailhousing and speedo arrangement. I'd still like to see you in the 3.42:1 axle range to be able to use the OD

Or, you could find yourself an M20 or a 2.64 1st gear T10 or a similar Saginaw 4spd and jack the axle to a 3.55 or 3.42

Or a 2.88:1 T10 or similar Saginaw and your current axle. Avoid the 3.xx 1st gear T10s and Saginaws...not strong enough and parts are hard to get.

If your motor is running now, don't mess with it. Fix the brakes, get a better axle (3.42/3.31 or 3.23s) and put any of those transmissions in it I mentioned...THEN build a solid motor and make it an awesome driver that rides nice, stops good and has a bench seat and 3 pedals
