My GN needs a cam. Recommendations, manufacturers?

If your heads and or block been machined the over the counter pushrods will be too long. Get a pushrod length checker to make sure. This may have also wiped out your first cam.

Definately. I'll contact the fella who I purchased the car from and get block info.  :prayer:

Block info.... I can help you sir.

109 casting, made of iron, 6 cylinders, 231 CID. Am I missing anything?  :finga:

I have the old Poston 202/202 cam and I think it's great. Pulls hard and ZERO lope at idle.

Since when did your Buick run?

My GN isn't broken, it's waiting on a turbo and IC that I just can't afford. When it was last on the street it ran like a motherfucker. My setup is, IMO, pretty awesome.

Already ahead of you. As soon as its up and running, Mr. Marshall will be getting whats left of my hard earned money  :psix;

[DCEPTCN]

Well, $75 bucks of it anyway...or have they gone up? At any rate, that is some of the best money you can spend on you TR.

He isn't doing the work himself, and the heads are being pulled off.

IMO, the clown he bought the car from just slapped the engine back together to get it sold. I know the story behind it, but I'm not at liberty to say anything. Bad deal. :mad;

Here's the latest update -

The engine is on the stand, and the heads are at the machine shop. I'm having them checked and all valves/springs/seats replaced if needed. Hopefully I'll have them back next week. No diagnosis on them yet, but the way it looks to me is that the valve is not the correct one... Not sure though.

I got my new cam, lifters, and pushrods from Full Throttle. I dropped them off the other day. Once the heads are back, re-assembly can begin.

As my good friend 1twisted6 stated, I bought this car from a "GN guy". He had a couple TR's sitting around (one of which was a GNX), and a few other Buicks from the 60s and 70s. I bought the car for what I felt was a damn good price, and the recently rebuilt engine had approx. 200 miles on it as I was told from the previous owner. I bought the car, and drove it very gentle for the first 1000 miles of ownership. I found some loose bolts, turbo oil line fitting to the block was finger tight with no teflon on the threads, loose oil pan bolts, etc. I signed the paper saying 'AS-IS'. Not really a big deal to me, and I expected to work some kinks out of it anyhoo.

I drove the car all summer problem free. 1twisted6 helped me tune the car to get decent boost - was only getting 10 psi, changed the solenoid and adjusted my wastegate actuator - set up a scanmaster, and added a boost, oil psi, and temp gauges. Throughout the summer, the tranny got softer and softer thru a 2-3 shift under WOT. I knew what was coming next... and planned accordingly. I knew it wasn't long when I wasn't getting any lockup in OD. However, I didn't plan on a top-end rebuild either, but thats the breaks. My friend who is doing my engine work couldn't find anything other than that valve and a worn lobe... He thinks the original cam just wasn't broke-in properly.

Hopefully it will be better than when I got it. I have really gotten into these Turbo 6 cars since selling my 60's Muscle cars. I still love a throbbing big block thru a pair of Flowmasters, but when I made the decision to start a business something had to go... And the big $$ went just before the market tanked. Someday, I'll have another to park along side my Buick


More updates to follow. Thanks again to everyone for there help, I greatly appreciate it.
