Hello again guys:

Here I go again. I can never leave things well enough alone. I'm making plans again to pull out my 2.6L, and install a 4.3L Vortec. Has anyone here had experience with the process, and/or can you point me in the right direction. I've spent a little time searching in the Isuzu archives, but can't seem to get a hit.

Here is what I have in equipment:
95 Chevy 4.3L Vortec
95 4L60E that came with the above motor
Dana 300 Xfer case.

I'd like to stick to the 4L60E because I'd still like a little economy when I decide to drive the vehicle long distances. On occasion I still us it as a daily driver. The Dana 300 seemed like a no-brainer because if it's durability and gearing.

I still have an IFS up front, but I'm unsure if the motor will clear the diff.

Any input guys?


Best regards,
Roberto Dean

I'm unsure if it would clear the stock diff... there is quite a bit of clearence with the 2.6, and I don't think it would be a problem. A body lift and a higher mounted engine would solve that problem. But would also raise the center of gravity.

Stinkbug on this forum has the same engine swapped into the same vehicle. Same t-case as well; but a 700R4 between the two instead of a 4L60E.

Yep I did the same swap. My 700R4 is the same tranny as a 4L60e but without the electronic controls. I dont know if the motor will fit around the stock front end, as I did a SAS at the same time. If you push the motor far enough back against the firewall You'll be able to run a stock fan and clutch up front with the radiator in the stock location. My distributor rubs the firewall, but I found out you can still fit everything with the motor another inch forward. You will have to take a BFH to the passenger side floor in a couple spots, but nothing too disgusting, also you'll wanna use stock S10/Blazer manifolds as they are the only ones I found that fit between the frame rails. Good luck.

The vortec engines started in 96, you sure thats what you got?

Sounds like a fun project <img src="/forums/images/graemlins/kewl.gif" alt="" />

1988 - 4.3 L Vortec 4300 V6, TBI, 150 hp (112 kW)/230 ft.lbf (312 Nm) (VIN Z)
1989-1992 - 4.3 L Vortec 4300 V6, TBI, 160 hp (119 kW)/230 ft.lbf (312 Nm) (VIN Z)
1990-1993 - 2.5 L Tech IV I4, TBI, 105 hp (78 kW)/135 ft.lbf (183 Nm) (VIN A)
1992-1993 - 4.3 L Vortec 4300 V6, CPFI, 195 hp (145 kW)/260 ft.lbf (353 Nm) (VIN Z)
1994 - 2.2 L L43 I4, MPFI, 118 hp (88 kW)/130 ft.lbf (176 Nm) (VIN 4)
1994 - 4.3 L Vortec 4300 V6, CMFI, 195 hp (145 kW)/260 ft.lbf (353 Nm) (VIN W/Z)

They have had different versions of the 4.3 since 1988. I had a 1994 Blazer with one and they were in alot of older S-10's.

Alright I stand corrected. I think it might be, the vortec v6 only came in s10s/blazers before 95, not the full sizes, which I was looking at.
