If it is broken, I would adapt a 4 bbl carb linkage to the 2 bbl carb. Stick with the 326. the parts might be hard to find, But you will absolutely LOVE that engine!!!

I want to stick to the 326 but at least change the carb

You can get a used Edelbrock performer and a small Holley and it will instantly get faster!!!

If it runs, I would do that. If it needs a rebuild, do it when you get it back together..

well before getting to the body we want to re-gasket the engine. since the body is gonna get worked on might as well work on the engine check for low compression to be 100% sure, check pistons, cylinder walls, valves etc... i guess rebuild the engine with some minor add ons. was thinking at least a cam, push rods, springs, a cam kit in that sense. an intake and carb. and some headers so ti sounds nice. i dont want to go wild at all. along with the engine. rebuild the tranny for problem free shifts.

Two things.....

1. 068 cam will be a monster. I have it!!! You can buy it at almost any parts store. Melling part number SPC-7. New lifters try Rhoads... I have been thinking a 326 with an 068 with Rhoads would be a great engine!!!

2. If you have the 2 speed ST-300, DUMP IT!!!!! A TH350 will bolt up in the same spot, you can use the same torque converter, same driveshaft and the same shifter. Bolts RIGHT in!!!!! Plus you get the advantage of a 2.52 first gear instead of 1.76.

1. im going to check out that cam and lifters, what about push rods, springs, and rockers?

2. how can i find out what tranny i have? i do have a TH400 from an old build..

1967Tempest · 08-06-2012, 09:34 AM

Well, the cam should be small enough for the springs and stock rockers. Just go to an adjustable valvetrain. If you do not rebuild engine just use the originals. Check the pushrods and if they are good you can use them.

Is the TH400 a Pontiac transmission? You can use that no issue, but the driveshaft might need to shortened.

You can take a picture and post it here. We can I.D. the trans. The difference of the BOP (Buick Olds Pontiac) trans and a Chevy is the bolt pattern. They are the same trans, but you might need and adapter to mate the engine and trans together.

oh ok yeah ill take pix when i get home later today. any suggestion on an intake manifold? used or new? i can buy new its not a problem but sligtly used isnt bad either lol

1967Tempest · 08-06-2012, 09:59 AM

You can find an original 4bbl intake or a used Edelbrock. I think I got a great performer for less than 75$. Either or.

You can look in the Performance Parts section of this forum and might find one. You can also put a wanted ad. You will get a LOT of people who have one for sale.

The Original cast iron and performer are identical as far as performance. The edelbrock is MUCH MUCH lighter.

You will get mixed comments on which carb to use. My .02$ is an original performance Holley 650 with vacuum secondaries or the Street Avenger 650. Available off the shelf and rather cheap. The quadrajet is a great carb, but you have to buy it then adjust it for the 326. Go with the Holley instead of an Edelbrock.

Have you ever worked on headers on a Pontiac??? Stay with the manifolds, and get a great exhaust. You will get very discouraged with headers.... My opinion...

i was also looking into this type of intake with dual carb from summit
http://www.summitracing.com/parts/EDL-54501/

never have i installed header but i have installed headers in my 03 sierra when i had it and in my Lightning, the Lightning was so dam uncomfortable and a bit but got it sone in an hour or 2 lol. can you explain this discouragement to me? do the stock manifolds flow good?

Jay Lightning · 08-06-2012, 11:16 AM

TTT...

1967Tempest · 08-06-2012, 12:10 PM

Yes they do flow good. I have them on my Tempest and they flow well and sound great. PLUS it took me like 20 minutes to get them in the car..

i see, stock manifolds it is. did you check out the link?

1967Tempest · 08-06-2012, 03:14 PM

I did. No issue using two four barrel carbs. BUT if you are going to go that route, you should rebuild the engine. At that point the lower end of the engine, i.e the crank, rods and pistons should be removed. The block should be cleaned and magna-fluxed. Then honed/bored and rebuilt.

More gas = more HP.. More HP= more heat. You need the cooling system tip top shape with no rust inside the block. PLUS!!! You don't want to put all that money into the top end with an unknown bottom end and have to get towed home. Ask me how I know that.....

dam. that seems a little over my budget for the time being. i guess a single 4bbl carb would be good then. ok i understand. but for shyts and giggles whats a rebuild kit going for? what would a machine shop charge for honeing and boring? i know they all charge different but what would be a guesstimation on one?

any info on pulleys and belt?
