Too much volume under the carb. If the spacer is not a 4-hole model, lose it.

Too much carb for a torque motor. Borrow a buddies 600 or 650 to try it out.

Too much cam for the compression ratio. Assuming a deck of 0.025" (since you don't know), your static compression ratio is 9.08:1. Swapping in a Crane #113941 (216/228 @ 0.050", intake closes 35 ABDC) and advancing it 4 degrees will give you a dynamic compression ratio of 8.169:1. Since a good strong motor will need a DCR of 8.00:1 to 8.25:1, you'll be right in the ballpark. I'm not saying use this cam and only this cam. I'm just giving you a for-instance of what specs I would buy if I had to buy you a cam. This cam makes power from 1,800 to 5,600 with valve float at 6,200 if you use all the matching hardware from Crane. Use a converter with a stall of 2,000 r's.

At 184 cc's, the heads should work fine for you. Eric thinks they are a little large and I agree with that for a torque motor, but hey, where do you draw the line on cost? Ideally, they'd be 170 but I'd keep 'em.
I agree about the gears. If I had to do it over again, I would do 4.56 in a heartbeat. With 5.13 gears, I wouldn't be able to still drive it to work (would be at too high rpm).

OK, the spacer is easy, that's gone. The carb is reasonable easy too, and makes sense. I think I will go with the Holley truck avenger for all the angles I have to deal with, although I heard some positives about the quadrajet too.

Two more questions then come to mind:
1) what about the intake? There was a suggestion to change it out. That's not the first suggestion I've had to swap it out, but will that really matter?

2) How is degreeing the cam by 4 degrees different than simply advancing the static timing by 4 degrees after the cam is installed?

Thanks for ALL the advice guys. It's very helpful. I can't promise I'll make all the changes ($$), but at least I'll get closer. The engine as is just does not make power where I need it (but it was a GREAT deal, so it's ok).
