Greg,
The green one is mine and it runs good with the 2 barrel and headers. Motor is the original with the 230 crank-rod combo, an Edgy Cam, shaved head, .030 overbore. Doesn't feel like much in 1st or 2nd (gearing, driver desensitized by faster cars, ?) but feels very strong on the highway. Car pulls hard from 60 to 85 mph. What's nice about the motor is that climbs grades on the highway with very minimal effort.
Trip was uneventful, motor ran at 180-185 degrees in the morning @ 55 mph and 190-195 @ 60 mph in the hot afternoon on the way home. The noise the original drive shaft makes got a little louder. The original suspension drove fine except for some occasional cross bouncing LR to RF. When I got home I noticed that the LR is sitting lower than the RR so the it looks like the LR leaf spring is failing.
