choochoo1996 Posted September 11, 2009 Posted September 11, 2009 Has anyone ever attempted a 2.8 to 4.3 vortex swap.....I recently was donated a 91 S-10 4X4.... with this power plant....My 2.8 is dying....we are talking 4.3.....700R4.......complete wiring harness....I need feed back on this soon......any thoughts....
Pete M Posted September 11, 2009 Posted September 11, 2009 it's possible for sure. see the novac or advance adapters websites for details and the parts you'll need. :thumbsup:
choochoo1996 Posted September 11, 2009 Author Posted September 11, 2009 Luckily for me I work in a welding shop.....with access to alot of equipment....so fabing isnt a problem....what I would like to know is has this ever been attempted and if so where can I find a good write up on it...I have searched for months and found nothing but the same questions I have....So I guess I better document this well .....
Geonovast Posted September 11, 2009 Posted September 11, 2009 Whoever bobbed the bed did an amazing job, I gotta say.
choochoo1996 Posted September 11, 2009 Author Posted September 11, 2009 Did I miss something....whats that mean....oops sorry....I just got it....No offence I hope....did it myself....shortened it 22 inches...I'm Canadian eh....lol
Pete M Posted September 11, 2009 Posted September 11, 2009 all the info I have in my head came from the advance adapters website (and that little booklet they used to give out). I would recommend starting there for tips
choochoo1996 Posted September 11, 2009 Author Posted September 11, 2009 this is what my engine sounds like .......
choochoo1996 Posted September 11, 2009 Author Posted September 11, 2009 Sounds worse then my Diesel 10 ton fork lift....anyway back to the swap....anybody ever tried it...
86FUBAR Posted September 11, 2009 Posted September 11, 2009 I was gona do the same thing on my 2.8 manch with a doner 91 s10 blazer but i figured it was easier to swap in a 3.4 v6 out of a camaro , so thats what i did :D now i have power !!
choochoo1996 Posted September 11, 2009 Author Posted September 11, 2009 but I have the whole donor truck....complete....
Geonovast Posted September 11, 2009 Posted September 11, 2009 If you've got the whole donor, time, money, fab skills, and the truck doesn't need to be running, definitely go for it. Is the S-10 a driver's side drop for the T-case?
86FUBAR Posted September 11, 2009 Posted September 11, 2009 I'm 99 % sure that all the ifs chebys are D-side drop
kro10000 Posted September 13, 2009 Posted September 13, 2009 well this may be more difficult than you think... the 2.8 v6 belongs to the gm 60 degree family, the 4.3 is of the 90 degree variety. the 3.4 is a 60 degree motor and a direct bolt in
Pete M Posted September 13, 2009 Posted September 13, 2009 Yup, keeping the MJ stuff is out. But he should be able to use the complete chevy drivetrain.
kro10000 Posted September 13, 2009 Posted September 13, 2009 Well if youre gonna do all that work might as well put in a cummins 6BT :D might need to slightly reinforce the chassis... maybe... naw :chillin:
Automan2164 Posted September 13, 2009 Posted September 13, 2009 Sell off the 4.3L Stuff, buy a 60 degree v-6. Pull out the 2.8, drop in the new mill, call it a day. Rob L.
Darren Posted September 13, 2009 Posted September 13, 2009 Going to a 3.4 is taking the easy way out. You already have a 4.3, and you said you work in a fab shop. A 4.3l in an MJ would be badass. Just do it already.
Rockyrider367 Posted September 13, 2009 Posted September 13, 2009 If you have all the drivetrain allready and have the fab skills I would go with the 4.3. I am also looking to put a 4.3 in mine in place of the tired 2.5.
kro10000 Posted September 13, 2009 Posted September 13, 2009 well if you are going to do the work you might consider just going SBC, you should be able to get a basic 305 or 350 for the 4.3
Pete M Posted September 13, 2009 Posted September 13, 2009 4.3 will be easier to keep cool. ask pilotblake about his v8 cooling issues. :D
Automan2164 Posted September 13, 2009 Posted September 13, 2009 Well if your are going to do the whole drivetrain and everyone is banking on your fab skills, sell the 4.3L drivetrain, and buy a 4.0L HO drivetrain. Put that in. Keep it jeep. The GM crap is what got ya into this mess. Don't put GM crap back in. Rob L.
choochoo1996 Posted September 14, 2009 Author Posted September 14, 2009 well guys, the 4.3 is in but I would not do another...I did this cause complete donor vehicle was free...there is not much room in there but it fits.....rear drive shaft needs 2 be shortened, front needs to be lengthened....t-case cross member needs mods....motor mounts need mods....switching from a standard means tranny shifter mods and t-case linkage mods....yeah its a lot of work but I forking love it....anyone else have a 4.3 vortex in their COMANCHE... :huh???: ....no......case close......Lets rock.......Next mods.....Dana 44....
choochoo1996 Posted September 14, 2009 Author Posted September 14, 2009 Sorry I posted my last pics before I read my thread, but thx for the inpt guys...I6 don't fit in the 86,I had a hard enough time squeezing in this vortex...rad location is the same, 3/4 inch fan clearance....1/2 to 3/8 clearence around inside frame rails.....she is tight....custom exhaust will be work but Ill get it....keep you all posted....I GOT A FAWKING VORTEX IN MY COMANCHE..... :help: :clapping: :rotf:
