Use a T-5 from a 1983 - 1987 S-10 truck with the 2.8L V8 engine ONLY! (.73 overdrive ratio) Use a 1983 - 1988 S-10 4WD axle with a 3.42 ratio. Use a G.M. HEI with a soft spring vacuum advance can (1973691) Use a Holley Weber progressive two barrel on the stock manifold. You should get 21 MPG @ 65 MPH. Tom John,

I suggest you check for a vacuum leak between the manifold and the head. This is a COMMON problem! Tom Pat,

They are similar but not interchangeable. The six needs a lot of help to be on par with the V8 with 100 more cubic inches. If your budget allows, there is 270 H.P. obtainable without boosting.

In. GMC engine (NOT Chevrolet) The engine is longer than your original 216 so it will be a difficult fit. Call to discuss limited availability of parts for this engine. Tom Al,

A 1981 chev pickup with a split exhaust manifold on the six cylinder engine. Would this exhaust fit on my 1962 chev 261 engine? Thanks Doug Hello

I see I found a place to buy several engine parts.. thanks you so much. First off I would like to know what engine I have, i think its a 235 GMC engine out of a 1954 1/2 ton truck... but I didn't buy it new, so may have been changed in those years? I found what appears to be a casting number on engine block... it was located on left side near the rear... its >> GMC 4 space 2324003 If this is not a casting number could you tell me where its located?.... I will be buying a Multi - carb manifold and hearders... plus some side plates. I might add that this engine is planning on replacing my 216 engine in my 1938 chevy.... a winter project. Thanks again for all you help, Al Hi Tom,

I suspect inappropriate cam specs. Tom Jonathan,

The worst is the valvetrain. Before pulling it I was having problems with the push rods bending. At first they were slightly bent so i replaced them and adjusted the roker arms to stock specifications(solid lifters). Then before pulling the engine I took the valve cover (4 screws) off and noticed that 3 more pushrods had bent almost to the point of breaking. Then after the engine was out I pulled the head and noticed that the intake valves were hitting the pistons. After researching the casting numbers I think the head is off a later 261. The casting number and date code is #3836850/date: A 19 1 . Im getting a performance kit to rebuild the engine. Then adding a Saginaw 4 speed 3.54 first gear with a 3.55 rear gear. Any thoughts or tips on that and the problem would be greatly appreciated. Sorry about the length sir, I hope its not too much of a problem. Thanks, Jonathan Mr. Langdon:
