Guest Anonymous Posted March 21, 2001 Share Posted March 21, 2001 Is it possible to swap a 302 in a 1970-73 240z, while using that stock trans and rear-differential? Can the rear end take 300+ horse power reliably? Thanks ------------------ "Anyone who is not shocked by quatum theory does not understand it."

alsil Posted March 21, 2001 Share Posted March 21, 2001 You can't use the stock tranny, but you can use the R180 rearend if you don't push it too hard. But if you're going to swap in a 302, I would suggest an R200. But if you're on a budget, an R180 will do, but you should replacce it at the first sign of noise. It will blow if you push it too hard. The R180 has a 7.2" ring gear, vs. the R200's 8", which is bigger than the stock Z28 ring gear on the new models. The axles are a weak point, too, but as long as they are in good condition, you should be OK. ------------------ http://zcar.netdojo.com My Upcoming Solo Album Site Quote Link to comment Share on other sites More sharing options...
