My 1968 Olds Cutlass S. I installed a 68-455 F block into it. has the following internals TRW 10:5.1 pistons, stock Nodular crank, rods. Edelbrock 6051 heads, aluminum roller rockers, Comp Cams pushrods Comp Valve springs, Comp OL320H-10 hydraulic flat tappet cam. Biggest hydraulic cam Comp makes for Olds 350-455's. MSD Billet distrubtor, MSD 6AL box, MSD Blaster II coil. Hooker Headers, Offenhauser Tunnel ram two Holley 1850-4 600 cfm carbs, 25 power valves, balance quick change vacuum diaphram housing covers 50 CC pumps. The transmission is out of a 77 Pontiac Grand Prix with a Hughes 3000 stall converter. Rear end is a Chev 12 bolt with Dutchman Billet axles, Aburn posi unit with 3:42 gears Fuel pump is Magnafuel Prostar 500.
I bought a brand new pair of Holley 1850-10's. These carbs were terrible. The castings were poor, they leaked like a lawn sprinkler, the sealing ridge in the gasket flanges was non-existant in some areas. These carbs also have no external float adjustment on them. They were so bad I traded my friend out of an old set of -4's on his race car, bebuilt them and gave him the new ones. He had sold the car and the new owner just wanted some carbs to put with the tunnel ram on that motor. I was glad to be rid of them.
Sorry for the lousy video I shot this with a digital camera holding it while I was trying to drive, but you can still get some idea of driving it.
