    Thanks guys!

    Cool - thanks for the info... Just did some looking around and it looks like GM sure had some crappy engine options in 88... either a 185hp/258fp gasser or a 143hp/257fp diesel... I was thinking for sure I could find some overlap between the SFA and the 454....

    Any of you guys have a good solution for an SFA GM with a strong motor in it that doesn't involve ripping apart the drive train or suspension?

    Edit: did a little more digging... looks like 87 was the last year for the SFA... Also had the 454 as an option... I guess that's what I be lookin for.. Thanks for the tip on the year - that ball park range got me what I was looking for.

    I thought they went to the new body style in 88 with IFS? not 91

    The 1 tons didn't change until 91. Kinda like how you could get an obs (88-98 style) in 2000 as a 1 ton.

    I believe the 1/2 tons stopped in 87, blazers and suburbans 91, 2500hd and the 3500 also know as V3500 last year was 91, now to confuse you more, you could also get a 1 ton or 3/4 ton pickup in ifs or sfa from 88-91. 92 and up was all ifs with the exception of the 3500 HD.

    But the 3500HD was RWD dually only, right?

    This is so much easier than with the Dodge...

    "Can I get a SFA 3500 wi..."

    Weren't the 88-91 one tons only a 3+3 (crewcab) with a bed or a chassis cab, no bed?

    Why do you want a SFA ? or a 454 ? lots of people plow with out either one of those things just fine.
    its also fairly straight forward to take out a small block and install a big block

    Because a straight axle will carry weight alot better than IFS

    He didn't say 3500HD but yes the actual 3500HD's were 2WD as from GM.

    Some of you guys are close, some are right on, and some missed it by a mile so here's the details.

    Yes a 1 ton SFA could be had all the way to the '91 model year and in ANY cab (or chassis) configuration.

    And yes you could get BOTH an IFS and SFA truck in a 2500 or 3500 between the '88-'91 model years.

    The IFS haters would like to believe so but it has nothing to do with the axle design..it's all in the spring specs. Swap a set of XG coded T-bars into an IFS truck and it'll have more load carrying ability than any leaf sprung SFA 1 ton GM ever built.

    Ive had a 04 duramax for 5 years. Hang a plow on the front of a STOCK F350 and the same blade on a STOCK GM 3500 and see which one drops more. Crank the t-bars and add timbrens they are alright but they ride to low with a plow for my liking.

    Thats the difference in spring rate...has nothing to do with the suspension design difference.

    Well the way GMs are designed they squat with heavy plows. Im not saying the front ends on GMs trucks are garbage, mine has held up pretty damn good with very little repairs in 5 years of plowing. They just dont carry heavy plows very well like 810s and 9'2V's. Thats why I only have a boss 8.5ft straight blade on mine.

    Sure, they're not garbage. They're just too lightly sprung as they come from the factory. The heaviest factory installed spring ratings on the GM's are several hundred pounds less than the lightest rating on a super duty. Which is why the supers hold the weight better stock...in most cases. But there's also plenty of guys out there that also have to upgrade the springs on the supers if they didn't option it with enough spring in the first place either.

    Plenty of guys out there too who are running plows weighing 900 or 1000 lbs or even more on the GM's for years with no problem after a spring upgrade....me included. You just have to know what springs (T-bars) to install...and watch the frame. :cool:

    Ok back on topic before jomofo yells at us for running his thread off track. :D

    I have an 8'6 EZ V on my 2500 HD I bet its right around 900 pounds with the 5/8 cuting edge more with all the snow that gets stuck to it. After 5 years of plowing I have no front end problems on only bottom out on rare occasion on lousy roads that make the front end want to bounce.

    I don't think this is really off topic. Its sharing ideas(what this forum is all about) and dispelling a rumor that you need a solid front axel to carry a plow. Same goes with a 454, while extra power isn't necessarly a bad thing I know people who plow with inline 6's and have no problems.

    Not at all! :drinkup: I've been round this a few times, but that's why we're all here far as I can tell...

    I want the SFA for the load carrying capacity and simplicity of design... I want the 454 for the POWA BABY! But I didn't start this thread to bash the IFS or small block (i-6 in a full size plow truck though, c'mon...) My buddy drives a mid 90's chevy and it's a great truck. To be fair, he doesn't plow it and if he did, I bet he'd be driving a ford or dodge. I just think the older GM's are damn good looking trucks and I'm looking to add a vehicle that is 50% emergency vehicle and 50% toy... The first 50% requires a simple heavy duty design that is easy to repair and has components that are easy/inexpensive to replace. The second 50% requires lockers,a big ass motor, and straight pipe exhaust. I'd probably put a mount on it just in case, but I might not ever plow with it. My dodge is warrentied for life, end-to-end - so if I'm going to ef up a truck plowing, it'll be that one.

    I have an 88,old style{square nose}V30 dump with the solid axle.As B+B said,only the 30 series stayed around in this form until '91.With the extra front spring I installed years ago,my 9-2 Boss hardly sags the front down at all.
