1976 Buick 350 Buildup. With Pictures!

Comp Cams 268H cam kit. Part #K92-203-4. The letter K stands for Kit. If you take that off and search on SummitRacing.com (where I got it from) it will bring up JUST the cam itself. It is, to my knowledge the second most "aggressive" hydraulic flat tappet Comp makes for this engine. Comes with cam, lifters, valve springs with internal dampers (do not need to remove for camshaft break-in), and valve stem seals. In the case of the Buick 350, they will NOT fit without machining. Different seals will work just fine. I luckily had a set and you only really need them on the exhaust valves but wont hurt if it's on the intake as well. They go ontop of the head in the valve spring if you didn't already know. Forgot to add, this cam makes this engine idle a bit choppy and makes it way more peppier than the stock grind. Still a good street cam. I also recommend a good rebuilt Q-Jet if you can get your hands on one. EverydayPerformance has a website I got mine from.

Oh yeah, this thread. After getting the thing broken in, finding I had no oil pressure, fixing that, the car behaves pretty well. Seems like it has a slight miss under 1500rpm and oil on the #3 or #5 spark plug, can't remember. The way I see it, is the miss can be attributed to timing issues, or a rounded cam or bent pushrod or straight up having the wrong spark plugs in the motor. Engine still runs great and pulls pretty good with the poopy 2.29 gear open diff and leaky TH350. Later today I'll pull the driver's valve cover and check the rockers for adequate movement. If it is a rounded lobe, no big deal. Cam changes aren't hard. Easier than a SBC. 😛

Video of Regal running. This was a couple weeks ago.

Took the VC off and had the engine running. No bent pushrods or busted rocker arms or rounded lobes to speak of. Might be a bad plug wire. Gotta check resistance soon. And as you can see they are just laying on the motor. Soon I want to get some universal cut to fit ones with 45 degree boots on the plug side.
