Excepting for Pontiac's OHC I6 of the late '60s, in stock form about EVERY other American I6 is a boat anchor... Even most of the Pontiac engines were economy power plants, but at least it was available with a performance option... Quote Selected

Excepting for Pontiac's OHC I6 of the late '60s, in stock form about EVERY other American I6 is a boat anchor... Even most of the Pontiac engines were economy power plants, but at least it was available with a performance option...Overhead Cam (OHC-6)The OHC-6 design was adopted by Pontiac in the 1966 model year. The block was based on the Chevrolet Straight-6, but had block and head castings unique to the OHC. Both head and block were cast iron; only the large cam carrier/valve cover was aluminum. The engine featured a Single OverHead Cam and was the base engine in the Pontiac Tempest.The Pontiac OHC-6 engine shared internal dimensions with the standard 230-cubic-inch (3.8 L) Chevrolet I6 block. The OHC head design put it in the avante garde of Detroit engineering. The single camshaft was supported by journals within the aluminum valve cover: no separate bearing shells were used. The cam was driven by a glassfiber-reinforced cogged rubber belt, instead of the usual metal chain, making it state of the art for the time - and very quiet. Valves were opened with finger followers (centered under the cam) that pivoted at one end on stationary hydraulic adjusters. The oil pump, distributor drive and fuel pump drive were not within the block, but were handled by an external jackshaft in an aluminum housing that bolted to the right side of the block. The jackshaft was driven by the rubber timing belt. The head had a single port face (exhaust and intake were both on the left side) and the valve stems were strongly tilted towards the left. This engine was used on the 1966 through 1969 Tempest and Le Mans and the 1967 through 1969 Firebird.A high-performance version, called the Sprint, was an option. The Sprint featured high-compression pistons, a hotter cam, dual valve springs, a split/dual exhaust manifold, a better coil and utilized the then new Quadrajet 4-barrel carburetor. It was the first American high performance six cylinder engine since the demise of the Hudson Hornet.http://en.wikipedia.org/wiki/Pontiac_Straight-6_enginePontiac Firebird Sprint for the win!The Pontiac six featured an overhead camshaft. Firebirds so equipped got 3.8 liter overhead cam lettering on both sides of the hood bulge. Pontiac offered an optional 215 hp engine on the Firebird Sprint models.The Sprint models a four-barrel Quadrajet carburetor and a hotter cam. The Sprint models got OHC 6 emblems on the front part of the rocker panels. The Firebird 326 models got a two-barrel version of Pontiac's 326 cubic inch V-8 rated 250 hp. http://www.uniquecarsandparts.com.au/car_info_pontiac_firebird.htm Quote Selected
300 follow up Reply #6 – September 19, 2009, 11:58:52 PM bhazard well in that case everyone was right! but i wanted to find out by going to different sites and finding it myself. i did find out that the 300 is already stroked out from a 240 so you cant really get any more cubic inches and have it be safe for the motor. and the head are like turbo coupe head and cant flow very well. HAVI you are right Quote Selected
