Anyone recognize this cam grind and what are the specs? Any info would be great. Also how does the condition of the cam look, is it reusable? The lifter faces looked nice, front cam bearing looked worn as usual I guess and the rest of the bearings looked ok other than they all had the same "impressions" in the bottom area of them almost like somebody staked them in like a galley plug?? Please see the pics. Cheers, Bob
https://liftkits4less.com/catalog/p...241-hydraulic-flat-cam-for-buick-400-430-455/ 227-241 sounds like a good cam, but there’s a lot of hate for Thumpers. (edit: sorry, Thumprs. cuz spellin iz fur dumys). Patrick
https://www.compcams.com/thumpr-227-241-hydraulic-flat-cam-for-buick-400-430-455.html Sort of like the TA C113 cam, but on a narrower lobe center (107*)
Awesome thanks fellas! I loved the sound of this cam in my old engine but I think it left some power on the table. The cam I got for my new engine is TA 290 94H I hope it has a good lumpy sound to it but helps with the power.
Here’s the 290-94H through 2 1/2” TA exhaust and Walker 17748s. https://share.icloud.com/photos/0J4GXdJ8uMLHQDbIykbq6-hZg#Oxford Patrick
It is, thanks! It’s a little rough around the edges but I drive it a lot and don’t worry about it. I really like the cam. Car is essentially stock appearing and ran 12.90s in BG last year. Patrick
I would have to say that the old Kenne-Bell - Mark C -107 camshaft was the ultimate in street nasty sound. However, with the right torque converter, 11:1 forged pistons, Stage1 heads, Turbo 400 transmission,Doug Throley 1-7/8 headers, Carter 1,000 CFM - Thermo Quad, Rossi -11 inch converter & Buick 4:30 rear gears was pure hell in the street. My only problem was there wasn't any qualified machine shops where I lived way back in the 70s. Now, there are some really experienced / professional engine builders that I wish I had access to many years ago. For the first 2 years of ownership, (January 2, 1970 - original purchase date) I couldn't get any high performance parts, not even headers. The aluminum intake / Holley carburetor, acell spark plug wires (which were junk - whereas, Packard 440 TVRS wires were the best & they came on my car), high performance ignition point set ( junk - wear out point rubbing block). The best ignition was to either purchase a Mallory dual-point distributor or have my distributor set-up on a sun-distributor machine using the little known high performance GM - ignition points / condenser set made for the BB - Chevrolet Corvette. They were the purist option that wouldn't destroy your point rubbing block and make 7,000 rpm without any point bounce. Those were the days!!!!!
