with vacuum secondaries, nah. it'll run just right. and if you upgrade down the line (cam, headers) it'll compliment those changes nicely.
Stock .318 upgrade!

68-9 best years of the 318 as it came from the factory.
Depends on which 4bbl, and which 2 bbl you might get better economy out of the 4 bbl. I did have 1 318 with a Holley that actually did pretty well all the way around. Stock 77 motor with 360-2bbl manifold and carb from a 76.

I found this set up that I can buy for under $300. But it has a 570 DP. This 570 may be a bit small?

That carb is a vac. secd. model.

That manifold uses the larger '70 and up 1" bypass fitting- you'll have to remove it and get a reducer and a 3/4" barb fitting for it to work on your '68.

No...Imo, if that carb is in good shape, that's a great price. Keep in mind, the stock 318 cam is all done at 5k, so it would be a fine upgrade for what you have now.

My heart sank today when, in the course of mapping out changing motor mounts, I was able to clean the area that has the production date cast onto it for my supposed "68" 318 as was described by the seller. 1-10-73 is just a bit off from 1968. There goes my extra compression point. I suppose with early 273 heads, it wouldn't have mattered much. Just chaps my back side for not checking to begin with.

Don't beat urself up on that. That's a beauiful vert. Not worried about big power, no problem.

If your heads are from the same time period as the block, then a plus would be having hardened valve seats.
