Bought this a while back to fix the fuel inlet on my quadrajet. Only used once, works beautifully and is a permanent fix for worn and leaky threads. It incudes the tap you need, helicoil installation tool, 4 helicoils and instructions. Makes is worth your while if you have a few carbs to do and don't want to disassemble them and sent off to have it done. If you have a drill press and angle plate at home you can DIY. Its easy. I paid $180 for this kit, yeah I know, it was expensive, but extremely hard to come by and would like to get $125 for it. I'll include shipping in the price. This works for all quadrajets 1972 and earlier.
I agree with that. There're are a pile of flat tappet Pontiacs out there with no cam issues at all. I didn't put mine in for any anticipated power gains. After two of my buddies had there camshafts fail within two weeks of each other I was just so afraid of having a cam melt down on me, I went for the roller for some supposed piece of mind. Didn't work out well though. I figured since I had the engine in pieces and had spent a pile of cash on it so far anyway, a roller set up would reduce my anxiety over the camshaft failing. I know of a couple shops near here that won't build an engine without a roller of some type.I guess it only takes one or two bad cams to make one gun shy. I don't know if all the failures we heard about a few years back were due to the oil like the cam companies claimed or if there were just a batch of bad cams. I remember a few years back factory Chebby cams were failing at an unusual rate. But I do know what lifter brand I would and wouldn't buy.
