Back in 1988 I installed a AMC 360 in a 1983 Eagle wagon.. it was way cool.

But you have to make a custom header for the left side of the vehicle to get the steering rod thru to the steering box.

And of course new custom engine/differential mounts.. I still have a pattern set.


I was able to use my stock 304 manifolds

I never considered using stock manifolds... I mean if your going V8... you gotta let the engine eat.

But I did use car in frame headers.

AMC V8 stock exhaust manifolds are nearly as clean flowing as headers. They even won an award for it.

  For sound no doubt the V8 has the edge, what a shame it was so hard to find in an AMC small car by this time (1976-80). I got some perf figures, Cadillac Seville with injected Olds 350 V8 automatic 0-60 mph 13.3 seconds (Road & Track Oct. 1975). Pacer X 258 2V automatic 0-60 mph 13.4 seconds (Car and Driver May 1976). Not bad, but a V8 always sounds better. Mind you, comparing stock 304 and 258 there is the weight distribution issue, which was mentioned above.
