Re: duration @ .050"/ .200"

Could someone please ‘splain what can be discerned by comparing two cams with the same duration @ .050", but different @ .200"? For instance, consider a cam, 236 @ .050", 150 @ .200", .340" lift, 108 lsa, as compared to a similar cam, but 152 @ .200". Does a degree @ .200" make more or less differe...

Re: Too late for a half fill?

Well my knee surgery has been postponed due to the Kung Flu.... I think I will fill one of my spare SBM blocks that have not been machined then run a hone thru the bores to see if anything has moved. The 885 is hard to find there is a dealer in CA that will ship one bag...$40.00 plus shipping. I th...

Re: Ignition advance at cruise rpm?

What's the motors actual cranking comp hot with the throttle wide open after 6 hits on the gauge? I've never measured it for this engine. It's got a relatively small cam, four valve head, etc. I've got a cruise ignition map from the factor for an engine that has about 8:1 "effective" compression ra...

Re: Too late for a half fill?

Why not take it back to the machine shop? :?: They can do the fill with an appropriate product and make the cylinders round again, if need be. Right now its a logistics thing... What about using Embeco 885? Users here seem to have good reports of no distortion after the machine work is done. That 8...

Re: Brake in oil

No1 is to have a good maintenance routine- the best filter could be reserved for those 10k oil changes;) Just in hand I like Mobil1, but probably will use Baldwin or Donaldson after the box of ACD is used up. A good maintenance routine is paramount. Personally, I use "Jomar" filters when I can whic...

Re: Engine Oil

Oil is really a personal preference as to many racing oils will provide great protection and power. As long as the Viscosity is correct for that engine and temperature remains in check, all the major brand name racing oils will certainly be fine. Especially when oil changes are often.

Re: Brake in oil

It's normal for the initial startup. No matter how well you machine the parts, you're going to have microasperities that contact and break off the moment you fire the engine for the first time. This is why I recommend a good filter with high filtration for break-in (ie: NOT a Wix XP, K&N, or a Raci...

The box size packaging of those two ignitions is not the same.
If you ask ... maybe they can upgrade to a 7AL-plus; ignition power only.

Re: LS stand alone ignition controller ?

Asking for a friend. Looking for a stand alone ignition controller in stock for a carburetor equipped LS engine. What are the options? I think his engine going in a older jeep has the 24x reluctor wheel. I have used the older 6010 MSD with no issues but, I have been told they now have another contr...

at idle it won't run pig, cow or chicken rich with a blown power valve.
It certainly will run super rich with a blown power valve because fuel goes right past the diaphragm in it, directly through the vacuum supply hole for it.

Re: power valve circuit myths

If my vacuum in gear is 6.0 and i install 8.5pv's, will the pv circuit pass fuel when i'm idling in gear? I currently have 6.5pv's and it does not pass fuel at idle. I have been told a blown pv with not pass fuel at idle. Only IF your throttle plates are open far enough so fuel is misting out of th...

Re: T slot questions

I get way more pump lever movement with the pink cams vs the blue it seems. I will get a little more time with it today, just trying to figure t-slot jet sizing thinking maybe this is the culprit. I currently have an .081 t-slot jet and thinking maybe it needs to be larger or smaller, but not sure ...
