Just went through this, collecting the bits and pieces for the engine build, have yet to find the time to completely finish it off/bench run it. I hope that the combination works . . .
I ended up with this:
Dual relief case opened up for 94mm barrels, case savers with 8mm head studs. Didn't need a line bore, close, but I heard that it's a bad idea anyway on an old case.
Stock crank drilled for eight dowel pins. (Decided to save the stroker for the 92mm case.)
Stock balanced (I hope) rods.
Teflon buttons. (Scared of the clips.)
Older heads opened up for 94mm barrels, 35/40 valves with the ridge "softened" where the squelch area meets the combustion pocket. Ported exhaust only. Match ported intake and exhaust manifolds.
Engle 110 cam and cut lube-a-lobe lifters.
Straight cut steel/steel timing gears. (I only did it for the noise.)
German bearings throughout.
Melling oil pump with an oil filter/oil pump cover. The pump cover then has an adapter to bring the oil to a remote filter, a cooler, and back to the pump. This is just 'cause I'm cheap, a full flow system is what you really want.
Mini sump/tuna can oil sump extension.
Lightened eight dowel flywheel.
Kennedy clutch and pressure plate. (Just 'cause I had them.)
Solid rocker shafts, stock rockers, finned and vented covers.
Single Weber DCOE side draft carb.
Mallory distributor, Compu-fire coil, Taylor wires.
JayCee pulleys, block off plates, fittings, etc.
Holley blue pump and regulator.
CB Performance breather tower with remote racing kart breather can.
And that's about it I guess. Still wondering if I did good, but nothing seems at all radical so it ought to run like a good stocker with a smidge more power for passing. Nothing special, but fun I'm hoping.
Luck,
TC
