yes, everything in the kit I got was stock besides the .030 over pistons. I also got my cam kit from them also. It was a complete comp xtreme energy k51-222-4 kit, thier price was $321.82 for that. Here is what the full kit is for a 350 http://www.motorpartscentral.com/Pro...?ProductId=993 . Call them and they will customize and get you what you want. Mine came with Fel Pro gaskets, so the kits might differ a little from whats on the website. They have more than whats listed on the website.

But maybe this isnt what your looking for since you didnt want to take it all apart. I would say just get some headers, a good 4 barrel, get the CR up, and since you are changing top end stuff get a cam.

[AdamHoud]

Hmm, I want to boost it up a little though.

[se428bandit]

adam find a set of 68 thru 70 350 heads 47,17 or 11 casting it will bump the compression a little,068 cam adv 4 deg will help out on the bottom end power.And try to find a 3.23 posi from a T/A and run a 2 1/4 in dual exhaust.

[AdamHoud]

I see some 46 and 16 heads going on ebay, which CR is 10.5 and 10.75 respectively. Is this just way too high to make work?

[Peckels]

A 72 cc head like a 46 will put you around 9.0 not 10.50 .

What B-man and Ace said. Yes, a 350 Pontiac can hold it's own against other sizes and brands of engines very well.

[AdamHoud]

Goquick, any advice as far as which heads I should try to find and how I should build them? I need to find a cam also, (068?) and I want to get a rebuilt qjet 4bbl and stock intake manifold(72ish?). At the same time I will add some Dougs headers and convert to dual exhaust.

I learned plenty about the incredible capabilities of the 350 from you Byron.

Enjoyed reading about your 9-second 350 engine.

[AdamHoud]

I just found some 68 cast 17 heads that have already been redone for only $125. They look like new. Should I jump on this?

[Will]

Yes.

[AdamHoud]

What about these:
http://cgi.ebay.com/ebaymotors/ws/eB...1293725&rd=1,1
They are rated at 10.75 on a 400 that year, vs the #17 which is rated at 9.2 on a 350....

[Will]

Because the 350 displaces less than the 400, the compression ratio will be lower on it using heads with the same chamber size. Assuming 72cc for those #16 heads, they'll produce the same 9.2:1 on your 350 as the #17s.

The #16s do flow better with large valves, and screw-in studs are an advantage also but you may have problems with valve to block interference if running a cam with much more than .450" or so lift and you will end up spending a lot more on them as their initial purchase price is higher and the ones in that auction need a complete rebuild.

I'd go for the #17s instead.

[AdamHoud]

Ok, hes going to ship them up to me next week.....I might have them ported once I findout what all has been done to the heads already.

Onto my next item, I need to find an intake manifold and quadrajet carb to rebuild. Should I get something and rebuild it myself or is there someone to send it out to? I was about to order jim hand's book and I saw the cliff book for rebuilding quadrajets.

I found a couple on ebay....

or this:

And for the intake manifold, I can use pretty much any 68-72 manifold correct?

[goquick]

Adam, 2.05" intakes work very well in those 17's.

[goquick]

Actual compression is closer to 8.9 with the typical uncut 72cc heads. I like the 068 cam for a mild engine combo. Advance it 4 degrees. Use 1.65 rockers and a spring like the Crower or Crane drop in's work great.

[surfnuke9]

Not to thread highjack, but my "stock" 68 with #17 heads, heddman 3 tube headers, pypes 2.5" with an x pipe and 2.56 gears feels like a beast.

much more and I would buy stock in a tire company.....then again, I do treat the gas pedal like it is an on-off switch.....

[Will]

A Q-jet is a great choice though I don't know how I feel about buying one off Ebay. There was a time when the wrecking yards were full of them, but I guess that's not the case any more.

Yes, any '68-'72 intake will work fine. Later intakes will work okay too, but they are even heavier because of the EGR provisions and you will need a '73 or later valley pan for them to fit.

[AdamHoud]

Well I have a 73 valley pan on right now, so an earlier manifold will fit right?

[Will]

Yep. The '73 and later valley pans had a deep relief in them to clear the big bulge on the bottom of the '73 and later intakes, so this just makes even more clearance under the earlier intakes.

The deep EGR valley pans also become a nice little swimming pool every time you wash the engine.

Give the local mice a chance to take a refreshing dip before you finish drying your engine.
