Dean, factory brochures always list dry weights, my cars aren't heavy, in fact my 86 is quite light (no sunroof, saves aprox 40 pounds). I believe from your weight list it was established that removing the entire ac system could save 40 pounds. Well, I had a complete 7mgte turbo system, including exh mani, ct26, oil filter relocater, intercooler, and all stock piping, and I shipped to a guy in pennslyvania, it weighed 80 pounds. I'd love to see some weight values between 7mgte and 5m long blocks, but I doubt the 7m is any lighter. Yes its missing the separate (and heavy) cam towers, but it has twice the number of valves, springs, retainers etc plus the block has oil squirters. Ophirs car also has hard pipe plumbing replacing the stock 7m plastic stuff, and heavy ass rims. So if the only thing missing from the car is the ac, with driver I'd expect it to weigh at least 3300 pounds with a 150 pound driver. I say the scale is wrong. I've weighed 3 different 85s and 86s, all stock with approx 1/2 tank of gas, on mulitple different trucker scales, and the numbers have always been between 3040 and 3080.
