I am upgrading my 78 to the 'bikers choice" Vulcan lifter/block/pushrod set up. i will be using an Andrews A2 cam.
Since it is now to be a bottom up oiling system, should I plug the upper oil lines? The only instructions that came with the set is how to adjust the pushrods.

Another note; this is a very nice machined set, looks like a quality product.
Known mods are, S&S E, and one piece baffled exhaust and a crane H I4. The heads are not HD, but I do not know the manufacturer, Exhaust port looks stock. I don't know about the intake.
Thanks

 

The vulcan kit has no provision for oiling the rocker arms...like the jim's and s & s kits....so oil lines have to stay

 

those are evo lifters -- 20/50 wt oil -- ok IF ya live in cold weather -- in AZ ya probably use 60 or 70 -- i run 70 wt ultima in new orleans -- but i have solid lifters -- thick oil doesnt work in evo lifters --

 

in the heat out here, 60 or 70 wt is more like 50 wt. That is why we use it. This is the first I've heard that a multigrade needs to be run with these. I know many people that run evos with 60 or 70 during our 120/130 heat. Why would it be any different than those. Are there any known problems or are they too new to have info. Thanks

yes. might take a while to get the noise down until motor warms up.

 

I wouldn't run 70 wt with them but 50 doesn't hurt a thing I ran it with my Jims lifters for years .

Leave the external oiling on it you need it to lube the rocker arm bushings . What I would do is an old fix we used to do on shovels as the upper ends are over oiled anyway . Pull the fitting on the cases and solder the small hole shut then take a .065" drill bit and run through it . That's the actual port size it's supposed to be , came from a factory service bulletin way back when . You'll find you use less oil and the rocker boxes & orings won't be leaking as often .

 

Thanks for the info. I appreciate it. The sales lit I read stated that it was a bottom up oiling system, which is why I had asked the question. These will work fine and are a major improvement over the Sifton solids that this 78 came with. Again thanks.

 

If your going to hyd. lifters look into Vthunder cams , they are made for hydraulic's and work great in shovels . Unlike other brands they start making hp about 1500 RPM and the higher end ones to 6000 plus . I've used them for years and love them even in my bigger 88 & 93 inch motors . Only thing you do need to install a high lift spring kit on the valves . Worth the effort , makes a solid daily rider with HP you actually feel & use . Quits a lot of the motor noise too .

 

thanks for the info
