Wait... I have an idea.
What if.... I placed a torqued case butt end to the table on the mill. center the main bores under quil, and then used a dial indicator to measure run out?
Would this be the most accurate method? Or is using a dial bore gauge and averaging numbers better?
Thanks |
Short answer no
long answer....still MOSTLY no, but working to determine the diameter of half a hole could be a learning experience. it is possible, just. very difficult, and why it's difficult well is maybe something you just have to try to see for yourself. |

Cam looks good, you can use that.
New set of web, or engle, or CB lightyweight lifters IF putting that cam in a different case......
If you HAD the case that cam and lifters came out of, then just put it right back in, looks great. Those are scat/web lifters
Don't idle and don't rev too high, keep the rpms IN THE MIDDLE of the rev range for the first 15 minutes. Not too fast, not too slow. Not too cold, not too hot. That's about it.
And use some good quality lube and oil.
calcium sulfonate complex assembly grease,
and engine oil that is recommended for flat tappet cams. |
Awesome! thanks for the help. Yeah, i dont plan on using the old lifters, but I figured Id take them just in case.
Im thinking about polishing the cam lobes and removing the Phosphate coating. And for sure, im going to chamfer the edges. Even if it doesnt do anything, it makes me feel better 
Im guessing "calcium sulfonate complex assembly grease" is or is like cam shield?

Maybe i will try it just for the experience  I guess if I really wanted to I would use the bore gauge and try to find consistent, matching results using the mill method.

Your 86a will have 108 LSA, on anything other than 108 web would have stamped whatever the number is on the flange. Your cam is old before web went to their part# system where the part# would tell you what it is, but you have to call or email them for the info.

Awesome thanks! 108 is exactly the number I was hoping for.

I was finally allowed to open the package lol. Looks great. I'll be polishing the lobes tho jpaul style. Makes me feel better.
Thanks Mathew!
Although... what should I do with the lifters? I will be running TP followers. Are these potentially useful in another build or trash?
P.S Mathew, do you have dogs? The cam smells like dog.
Edit- oh and yeah. 96 grams  sounds like scat

A while back I saw a yt vid showing at roller tip rocker at high rpm. Can't find it now. Anyway, what surprised me was how fast the roller tip would rotate when the valve closed. Basically the valve stem is throwing the tip at high velocity and when the roller leaves the tip it has an induced high rpm. Then when the opening ramp arrives on the scene this rpm skids to a stop on the valve tip.
I DID find this interesting vid showing beehive springs in action.

I find it interesting that one school of thought says you can’t re-use the matched and marked cam and lifters in a different case. The Bergs used to have a partial engine just for the purpose of breaking in your cam and lifters for you. I believe it was turned by an electric motor. They may still offer the service…

I always remove the phosphate coatings from the lobes. I consider them abrasives -
I am old school micro-polishing fanatic. I use micro-finishing tapes used in the aircraft industry. I sent some tapes to a guy in Germany when I sold a lineborer. He loves them!
Micro-finishing tapes are not the same as regular sandpaper. YOu cannot rip them apart. It is like a tough belt make of some silk.
I use these tapes on the lobes and lifter bodies and heads.
I like the idea of running those VFR 800 TBIs. It is a real nice alternative to expensive WEBERS or DElls. Maybe even run the motorcyle coils and things. Lots of machining fabs - if you go that route. I am sure it is well worth it. |
