Engine Backfire Diagnosis Led to Wiped cam Lobes
If you don't have brakes, then you have a major vacuum leak somewhere, which would make it not want to run at all. may need to try a different base gasket, and make sure it doesn't block the primary or secondary butterflys. That gold canister on the rear of the carb should have a vacuum line...- Quadrajet Power

Engine Backfire Diagnosis Led to Wiped cam Lobes
by the way, I wanted to point out that I stand behind my work, so if anything is determined to be carb related, I'll take care of it, so don't worry about that.- Quadrajet Power

Engine Backfire Diagnosis Led to Wiped cam Lobes
does sound a lot like a vacuum leak. Make sure all of the ports on the carb are used or plugged.- Quadrajet Power

Engine Backfire Diagnosis Led to Wiped cam Lobes
If the choke flap is open, then the electric choke should be working. Like Ceas said, you probably need to adjust the mixture screws for best idle. They may need opened up. I cut slots in those screws so you could use a flat blade screwdriver. May need to turn them out a full turn and start...- Quadrajet Power

Stumbles shifting into 2nd while heavy into the throttle
Here is a link to my price list. I try to stay very affordable to help people keep a quadrajet instead of going to some auto store bolt on!! I replace most of the parts inside and in your case, would resize the idle circuits to run correctly with your cam...- Quadrajet Power

Stumbles shifting into 2nd while heavy into the throttle
yea, sounds like a rebuild time. That carb, I think has the hot air choke, with canister on the side. You can convert those to electric to help the operations. Something to consider. If you build your carb yourself, make sure you get good parts, and not a parts store kit. Those are crap...- Quadrajet Power

Stumbles shifting into 2nd while heavy into the throttle
Hi Shane. I'm new on the board, but not new to the carbs. What carb are you running? A quadrajet? When you changed the cam, you change the vacuum structure for the engine, and that can require some internal calibration changes on the quadrajet for it to be it's best. Especially the idle...- Quadrajet Power

Not for reasonable price really. I use a special cut drill bit and set the depth. It has worked well for years, and I use it on every Quadrajet I build. Check with cliffshighperformance.com I don't think he list his bits on the site, but I do think he has them available to purchase. Cliff...- Quadrajet Power

Thanks everybody for the welcomes. 350runner, I bought the truck in all original tired condition. So I replaced all the suspension components, steering and brakes. 4 inch all spring lift, and added the tires using stock wheels. Engine/trans still remain stock at this point.- Quadrajet Power

350runner let me know about this place so here I am. Currently have an 89 K5 blazer, and recently sold an 82 SW with 383 and an 86 SW. Wouldn't mind finding another one. I also have a couple of 72 Buicks to go fast in.- Quadrajet Power
