Re: 8mm Stems and Keepers

I'm wanting to replace my 11/32 stems, in my SBF (306) with 8mm's. My springs are 1.55 with 1.48 dia retainers. The 8mm keepers, seem to fit the taper on the 1.48 retainers but, the stem sits to low, for my comfort. Can I use -.050 keepers with these 11/32 retainers and if so, where can I get them?...

Why did the 289 HP not have vacuum advance?

Did any other factory v8s not have vac advance during this era?
Lots of high performance engines of that era did not have a vacuum advance mechanism.

Re: Main Bearing Oil Hole Alignment

If you look at a stock block you would see that the two oil holes are side by side and the main oil hole is pretty much parallel to the cam feed hole making this a none issue. For some reason dart moved it away from the cam feed hole and off to the side so when you put the upper bearing in, it bloc...

Re: Main Bearing Oil Hole Alignment

Alright... Sorry to bother you guys again, but Main Oil Hole Alignment. The middle hole in the saddle goes to the cam bearings. The one mostly covered up is the main feed line. I'm concerned by how much of it is covered by the bearing. Should I do a little (lot of) surgery? As it is, a 0.078" drill...

Re: Bigger intake smaller exhaust valves

How big of an intake valve could you put in the common 23 degree head without it being 60/40. Would putting in a smaller then 1.60 exhaust valve help do it to maximise the intake valve size. I have seen a 2.125" intake with a 1.550" exhaust used on a turbo-charged application so, I know they will f...

Re: aeration from scavenge pumps?

Does anyone have any suggestions for sizing scavenge pumps vs. pressure pumps? Most of the dry sump systems I've seen have a single pressure stage and three, four, or five scavenge stages, often the same size as the pressure stage. So the scavenge pumps are mostly churning air. Is this contributing...
