I know I get pretty active on here but please don't let it mislead you into believing that I'm anything more than an adventure hobbyist. Basically just learning as I go along and maybe just a little bit better of the budget to allow me to make more mistakes. But I can tell you the car I have now came with a 7 and a quarter that I never ran because I already had four speed aspirations. I started off with a 8 and 1/4 that never broke with 355 gears in it but after I put a stroker motor in it I figured that was it. I sold it while I was still in good repair. And built that eight and three-quarter for over $1,200. And blew that up as I said within 20 passes. And I was right at about $1,200 with this Dana 60. I can personally attached that once the housings are all separated and all the axles are out and you just have an eight and three quarter housing with the part that holds the gears and all it's probably only a 20 lb difference at the most. The actual part that you're going to use. And mind you that way is right over your back tires where it's needed for traction anyways. I also forgot to mention that $160 Dana that I started with I was able to sell all of the brakes and axles for the truck stuff for $40 so it only ended up costing me a hundred and twenty. And I'm just saying this because you said bulletproof and doing it once the first time not 4 times like I did. If you don't mind that I don't go back and correct my voice command for the few things that I said wrong there I'll continue? If you like freeway driving with a tad of snappiness I would say 3:23's. A big Cam that makes vacuum. Refresh cheap home job rebuild on that transmission. That's probably the easiest part. once you tackle that easy Boogeyman it's all downhill...
