Greetings all: I've been reading the postings regarding right rear noises/problems but none seam to describe mine. I have a 73 240z with 93k miles on it, the car is mostly original with the exeption of the weber carbs and hooker headers. My problem is that when under med/heavy breaking the right rear susoension seams to be hopping producing a thumping sound. I had a broken right rear axel stub replaced 500 miles ago but the problem continues. My mechnic has offered a few sugestions but is not sure. The thumping olso occures when accelerating, to a lesser degree and there is a jump to the right on rough road conditions. Would a deteriated trans link bushing cause this? Or a bad wheel bearing? The car sat for a few years leading to the sugestion of a flat spot on the drum, but the mechanic say it looks ok. Any sugestions would be helpful. Thanks Ian

Hello everyone! My name is Ian and I am a proud Z owner since 1973 when I bought a new 240Z. It now has 93,000 original miles and is still going strong. I also have a 1978 280Z which is pretty rusty but runs good for spare parts.

I have a 1973 240z and I want to know if a 1978 280z head will fit. What I'm trying to do is get more horse power with the larger combustion chamber fron the 280z and not worry about using unleaded fuel in the 1973z which take leaded fuel, (the 280z doesn't). Also I want to get rid of the fuel injection system of the 280z and stay with carbs. Will the caburetored intake manifold from a 240z fit the 280z head? Has anyone done this swap?
