Re: [AMC-list] Quad 4 in 58-60 Rambler

[Wrambler <wrambler242@xxxxxxxxxxx>]

IIRC, ther quad was "cheapened" to a single OHC with 2 valve heads to create what was at first called a "dual" four.
I suspect that may be the pre ecotec engine. 
If so the 96-2001 would be a much better choice I suspect.
The difference between the dual and quad engines was VERY noticeable.

Stay away from early Quads! 
They are not worth the effort to build.

You just scratched the surface, but come to a great point -- you need to research a bit so you know which one to get. In general, the later ones have all the quirks and bugs worked out. Rather than a Quad-4 you really want a 1996-2001 "Twin-Cam". Same engine, new name to mark all the improvements. Any of those should be good to go. The rodder community calls them all Quad-4, thus a bit of confusion. I'm pretty sure the one the guy on hotrodders.com is building is a 96-97 model, but I'll ask.

The Ecotec appears to be based on the Q4 design, though of course thoroughly modernized.

In the spare time I don't have, I spent a couple hours in the last week
hunting info on the Quad 4 motor... OK it's only reading, but anecdotes from
rebuilders, hot rodders, etc...people in a position to actually know, not
blind fans nor haters...

It's a mess of a motor. It sure is pretty though! And makes a lot of power,
and ... but there's like 6 blocks, 4 cranks, 3 rods, not just because of the
two or three different displacements, but because of design flaws, head
cranks, weird gasket problems, ...
