Chevy SFA swap

Called a shop today and was told for a sfa swap I had to go at least 8-10" of lift for the diff. to clear the oil pan safely.Is this true?? I want to stay w/6" to be legal.Is there anything else I should know about this swap??
THANKS

Re: Chevy SFA swap

No it is not true. The diff on an ifs is almost touching the pan but the axle shafts go down from there you only need a few inches between the axle and the pan as long as the bumpstops prevent the axle from hitting it. obviously if the pan is only two inches over your pan and you hit a 6 inch speed bump at 60 it WILL hurt. I think 6 inches would be more than enough. check out O.R.U. for all the details. Oh yeah and do a SEARCH as this has been covered lots and lots of times.

Re: Chevy SFA swap

That might be true for a 2wd putting an axle in it, but not 4wd. I plan on doing a SAS in my 97 with minimal lift, maybe 4" over stock 4wd. For starters, you have to know what axle you want to use. If you want to keep your stock t-case, then you will need a Ford axle. Not cheap. Using a plentiful GM axle, then you have to swap out the t-case for one from an 87-91 Blazer or Suburban. The ORU kit gives you 3" and being my truck is 1 ton ext cab with a BBC, almost any spring I use will settle. I think I'm gonna use 2.5" springs, that will settle to maybe little over and inch. ORU is a good kit, but it's hard to justify $750 when you see the contents of the kit. I got another set from them when they had a "sale" in December, everything they had $100 off, and in the process of making some brackets.

Re: Chevy SFA swap

Yeah I finally got it mobile, and with all four wheels. I need to find an open 4:56 carrier so I can install the detroit and spool, and obviously the 4:56s. I need to do some small stuff to it, but I took it out a little bit. Man, this thing is awesome, even with open axles with 3:73s and 40" outdated tires!!! I took two leafs out of the front, it doens't ride too bad, and it flexes better than I thought. I can't stuff the tire in the wheelwell, at least don't think, but then I never tried. The old man bought a digital camera, but something about the software not loading on the computer. or I would have some pics up. It's supposed to warm up (20 degrees warm) this weekend, I'll get a cheapo camera and take some posure shots, and maybe some wheeling pics. It throws the mud pretty good, but all the mud as well as the top 6" of ground is froze solid, so no mud action pics. The hard part is done, just have to fine tune everything, and the small stuff that gets overlooked. I really need to get some CV for both d/s, even in 4wd low you can feel the vibes. I need to tear the front apart and regrease everything, and think havta get a shim for the front, I get alittle wobbling driving down the road.

Re: Chevy SFA swap

Sounds kinda high for doing that. But then again I'm used to doing everything myself. Bring it up here and I will do it for $4k!!! [img]images/graemlins/burnout.gif[/img]
