RickB Posted October 25, 2000 Share Posted October 25, 2000 Hey All, I am new to this particular swap and would like to identify the rear end and gear ratio in my 76 280. From what I've read the best choice is the 200 and I may be interested in that route. I am primarily interested in straight line acceleration, i.e. drag racing..though i like the way this car handles so I'd rather not go with a solid axle. How about upgrades to the stock rear end (assuming that's what is in it?). Spicer U-joints or? thanks in advance... ------------------ RickB 280V8 350/700R4 12.77 w/radials & pump gas so far... http://photos.yahoo.com/bornabovhttp Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted October 26, 2000 Share Posted October 26, 2000 Solid Us are supposed to be the hot ticket. I bought "Spicer heavy duty" U joints from MSA - they were hollow and drilled for grease - doh! Neapco #1-0029BF is supposed to be a solid joint. Note that I'VE not picked them up yet so I could be wrong - check before you leave the store. However if you want Spicers I've got a set here Quote Link to comment Share on other sites More sharing options...
RickB Posted October 26, 2000 Author Share Posted October 26, 2000 Thanks BLKMGK... Actually i thought i had deleted this post as i put it in the wrong forum. BTW, where can i buy the joints you quoted? Any decent parts store or?? ------------------ RickB 280V8 350/700R4 12.77 w/radials & pump gas so far... http://photos.yahoo.com/bornabov Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted October 26, 2000 Share Posted October 26, 2000 Rick, it seems like what works on one Z does not on another so its like flipping a coin. I have had good luck with the Neapco solid Us. I, like you, do more drag racing with the Z than anything else. I launch with 8# boost on a t-brake with sticky DOTs and then a V-8 Z puts that same axle set in his car and they break testing on the street with street tires. Go figure. I suppose any parts store that sells Neapco should have them, but I bought them from a driveline shop. My recommendation is to move towards the optimal IRS setup of an R-200, 280ZXT CVs, 280Z stub axles and adaptor. You already have the R-200 and stub axles, leaving the CVs and the adaptor but ironically that is the sticky part. The issue is, what is the best adaptor? If you are new to the forum, check out the excellent articles in the Tech Info section and look at past posts in the "Brakes, Wheels,.." and "Drivetrain". When you are done, you will be totally confused like most others but have a better understanding of the issue. ------------------ Scottie 71 240GN-Z http://www.mindspring.com/~vscott911/gnz.html Quote Link to comment Share on other sites More sharing options...
RickB Posted October 27, 2000 Author Share Posted October 27, 2000 Great reply Scottie, BTW...I've played with a GN engine for the past couple of years. From what i understand then the 280 already has a R200 though obviously no posi. So I will need solid U's, ZX turbo CV's and adaptor huh...hopefully i can get some help from a local GN/Z-car guy i think you are familiar with (Greg K from the Dallas/Arlington area). In the mean time I'll be reading and absorbing as well.

Scottie-GNZ Posted October 27, 2000 Share Posted October 27, 2000 Rick, you need solid Us in the stock axles OR CVs with an adaptor. ------------------ Scottie 71 240GN-Z http://www.mindspring.com/~vscott911/gnz.html Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted October 27, 2000 Share Posted October 27, 2000 BTW, Greg is a personal friend, very knowledgable in Zs, GNs or anything that goes fast and he is a super nice guy. Dont tell him I said that ------------------ Scottie 71 240GN-Z http://www.mindspring.com/~vscott911/gnz.html Quote Link to comment Share on other sites More sharing options...
RickB Posted October 27, 2000 Author Share Posted October 27, 2000 Doh...newbie mistake. Well then I'll start with adding in the solid U's and see what happens. I was planning on calling a driveline shop today. I've been racing once a month with Greg for a while now..you should have seen the match races with his brothers juiced Mustang thanks for the direction.
