GM HEI on 258?

I had thought about doing this swap. I found a detailed "how-to" online.  Follow this link to it:

It has just been too hot to be stomping through the yards so I went with a rebuilt points distributor from Advance Auto from a 1974 258. That is working fine so far (I just put it in about and hour ago).

Ditto! I have 2 and 1 used one waiting to be installed.

The problem was with V8 versions more than 6 cyl eating cam and dist gears.

Well, you hit the problem -- the knock-off companies may not do enough research to figure out what the adjustments are for each different engine. Sell it and let the customer figure the details out -- sort of like Microsoft does with Windows. After enough complaints they will go back and fix the problems and change part numbers. No complaints (or not enough) and, not enough sales, and it will go away (the AMC part, not Microsoft...).

If there are adjustable parts like the vac advance the HEI might not be adjusted to work well with an AMC engine. But they found out it physically fit, so that means a few more sales...  some user adjustment may be required. Seems like 4WD Hardware would have got someone to test it first, but big retailers often aren't very responsive, as long as it's selling. That's one reason getting something from BullTear is a good idea -- they do check things out before selling.

83 will have motorcraft..
