Shoot, GM put "big" Q-Jets on grannys Caprice Classic with a smogged-to-death 305.

Ok, I got a little carried away with "granny's Caprice Classic" but they did use a 650 cfm Q-Jet on some Monte Carlos with a 305 HO option; which is kind of an oxymoron, lol.

Hmm...

It seems more and more as I read that the 470 may even be slightly under powered for the 304, but there isn't any real science behind it, just opinions. And more than a few people are running Q jets on their 304s, and ALL seem to love it! Some even use the 750 CFM Q jets with great success. Looks like the way to go I suppose. I like the Holley TA, buts that a $400 carb, and even with the mods, the Q jets still seems to out perform.

Dada,

That's the same conclusion I came to. I believe there's something unique about the design that makes the Q-jet perform better than most at severe angles. When guys like John Nutter mention that many of his wheeling buddies use Q-jets on their 304s, and love them, I tend to pay attention. We'll see....

Based on the info from the thread I linked to earlier, it appears the stock Chevy 350 truck Q-jet setup works pretty well with the 304.

Great!

All I need now is some spare $$$

until then, I will run the hell out of this holley 2300. Unfortunately, I need a new rad, hoses, and fan shroud. My JB welded rad just started to leak, it wont be long until it completely goes. Might as well beat it to the punch

I bought a radiator, hoses, and timing gaskets, and I will be fixing some leaks and bad radiator stuff for the next few days.

I was planning on replacing timing set, and my cam gears if needed, but when I pulled the timing cover off today, I found an uncharacteristically clean timing set, cam gears, and timing cover insides. I'm not sure how sloppy a new chain is, I've only done a magnum 360 before. Does this timing set look as good as I think it does? I know it's hard to tell from the pic, but I'm almost certain this is hardly used.

I figure I'll post this here since it deals with my timing, plus I will be experimenting with why my HEI vac advance points at the radiator fan.

Looks really clean to me. I wouldn't mess with it the chain looks almost new.

And could you post a pic of the inside of your timing cover? I have some circular grooves in mine and I wanna see if you do too so I will know if I have something wrong.

Put the harmonic balencer on before you tighten the cover bolts. It will help line up the seal.

8,

That looks pretty worn, to me.

For comparison, here is what the one I pulled off my 360 looked like.

Thanks. What caused the oscillating circles though? Is there any concern?

so the vac line to the distrubutor should come off of the manifold and not the carb?

I'm no expert, but I believe it's cased by cam walk. The AMC V8s have no thrust plate, or button, to prevent the cam from walking back and forth.

When it gets too sloppy, like yours apparently has gotten, it will start chewing up cam and dizzy gears, and stretch timing chains.
