Velocity Stacks. Which ones?

cid_casterwick · **Posted:** Sat Nov 28, 2009 1:34 pm

So I've recently purchased some old school Mikuni-Solex side draft carbs in the 38mm variety for the 20R in my 76' Pickup and im looking at doing some velocity stacks. But im having a tough time with finding just the right ones. Im looking for a chrome or polished finish, nothing anodized or carbon. Im also having trouble with the sizes they're offered in, there doesn't seem to be a diffinitive 38mm option.

Any help would be greatly appreciated.

well from wat i heard about velocity stack is that they can affect torque depending on length...

Mikuni did not make 38mm solex. They are most likely 40mm. Just get some aluminum 40mm length stacks and call it a day. the longer, the more torque.

Maybe they did back when? These are pretty old

Those are emmissions era Mikunis typically on 18RGU engines. I consider them Junk since they dont work as well as the real Mikunis. You cant even get gaskets for those things. The bleed pipe and emulsion tubes are different and you neet to change them out. Good luck. I have 3 pair sitting collecting dust...

Well sonovabitch. Oh well FARK it they're going on anyway. If I really need gaskets ill use gasket maker. So if I need bits for them you down to sell them? Or if you want to sell another set let me know a buddy of mine wants a set.
