I just installed the General Springs 1-ton springs plus the Rusty's 0.75" rear shackles to replace the worn out half-ton springs and shackles. It lifted the rear about an inch when unloaded. I also put ZJ springs in front to replace the sagging front axle. The ride is more predictable and the steering more responsive.

Why does this site post my pictures upside down?

Update: still driving the 1986 MJ with the 3.4L swap, because the swap took all my $$ and nobody wants to buy this P.O.S. which now has about 15k on the rebuilt engine. Got some of the leaks contained, but the MJ is not welcome on sealed driveways. The Holley 2BBL sniper settled down, a little, after I installed "Livewires" from performance distributors.com. The Sniper still stalls, especially when it's cold out, but if I'm rolling, I just put it in 5th gear and clutch-start it, which means I don't need to pull over and crank-and-crank-and-crank at every intersection. I'm sure I've posted this before, but the Holley Sniper is garbage and Holley has taken no responsibility for this and gone so far as to release a Sniper2 without recalling the original Sniper. Not much power or torque increase over the 2.8L: should have saved up for an LS swap. Let this be a warning to Comanche owners everywhere: the Chevy 2.8L/3.1L/3.4L V6 engines are underpowered, gas-sucking pigs that are easy to overheat. Stay away from these engines. Also, stay away from the Holley Sniper. Next project: swapping in a Toyota 22R from my 1982 Hilux, once the 3.4L dies.

So the 3.4L swap is a failure. I don't know if I was supplied with a bad rebuilt engine or if the mechanic did not install it properly or if the Holley Sniper is to fault, but, after 8000 miles, I have oil in my coolant, coolant in my oil, and both staining my parking spot at work and I'm out $12,000. I will never trust an American-made engine again and I will never trust Holley again. Maybe I can mate a Toyota 22R engine to the Aisin AX-5 transmission, otherwise the Comanche is going to get crushed.

My GM 2.8L V6 engine died in my 1986 Comanche and so I had it replaced with a 1993 3.4L V6 Camero crate engine. It has a Holley Sniper and a DUI distributor with stock exhaust. Does anyone think it's time to upgrade to headers, dual exhaust, or larger pipes? If anyone else is considering a Holley Sniper, I advise against it. The Sniper won't self-learn, as advertised, so I will need to pay a Holley EFI shop $700 to dyno and tune it. It stalls at most intersections. I should have either upgraded to the Camero EFI or used a Weber carb. Now avoiding EVERYTHING Holley.

A good write-up for the 3.4L swap ( http://www.lunghd.com/Tech_Articles/Project_XJ/Project_XJ.htm ) says that the old 2.8L oil pan must be re-used because the 3.4L oil pan will hit the front differential. Would a 2-3" suspension lift (which I was planning on, anyway) allow for the retention of the 3.4L oil pan? I do not want a higher lift because I am concerned that it would result in undesireable drive shaft angles.

Okay, 4WD.com didn't really have anything in stock and said that nothing was coming in until NEXT YEAR! So, I called ATK directly (866-721-2315), spoke to Tom, who said I could order a remanufactured L32 3.4L longblock for $1930. Lead time is 8-10 weeks and I got an awesome shop in Cicero, N.Y. to do the swap, along with a Holley Sniper. Hopefully everything will be buttoned up before it snows in October. It seems that the Pontiac Fiero crowd got stuck with the same crappy GM 2.8L V6 and does the same 3.4L swap, so this is in no way reinventing the wheel.

Thanks. Will any longitudinal Chevy 3.4L v6 work, or is it just the L32 from the 1993-1995 Firebirds/Cameros? Are there new/remanufactured engines available or do I need to pull something out of a junkyard and hope for the best? I have seen new Chevy 3.4's for sale, but they are for 2006 model years.

I have a 1986 comanche with a dying 2.8 liter v6 engine. Everything else is good, but my mechanic says it's not worth fixing and I should sell it for scrap. The Novak site wants $15000-$20000 for an ls or vortec swap, which means the mechanic is right. I would make more money on youtube showing this thing getting crushed. Any VIABLE alternatives to scrapping what should be a salvagable comanche? (I am not a mechanic. If it is not bolt-on, I cannot do it. There are NO mechanics willing to do the work.)
