LT1 swap for an 86 monte carlo ss

[bigdan]

Hey Dave ,
i'm doing the same type of swap...
where did you get the cable? AKM sells it 90.00 it's lot of $ if i could get it for 50.00 id like that...

did you convert the harness yourself or idi you get a painless wiring harness or some similar type ?
thanks

My Opinion

The swap is scary at first but actually now that I started its fairly as simple as a sbc swap with more technology. Now it is expensive if you decide to go with the painless wiring kit, and ac relocated kit(as I did) But there are companies such as howell that make harnesses cheaper.I'm using a 255 fuel pump instead of the in-tank style for right now. running all mechanical guages and i plan to order a digital speedometer to coincide with the 4l60e.(not neccersary I just like how digital speedometers look) There is just as much power to be made in the lt1 as the ls1 again this is my opinion so if you could choose I would get a lt1 also make sure its out of a roadmaster, lac, or impala because me personally i think the cast iron heads flow better and thats the main difference in the lt1 you find in the trans am or camaro.

I'm doing the same swap for a 86 Monte Carlo... Besides the above responses has anyone came up with any new accessories for the swap. I want my ac / speedometer / all electronics to work smooth without a carb

You should be able to use all the factory accessories for an F or Bbody LT1. Corvette accessories are all on the driver's side and I'm not sure if they fit a Gbody or not since Corvettes don't have a steering box. You may or may not need to slightly notch the frame/crossmember for the AC compressor. Some guys say it clears, some say it doesn't. I've done several LT1 swaps but never in a Gbody so I can't say firsthand.

I've done 2 LT1 swaps. The first one was a 93' 5K mile LT1 Corvette engine from a heat chamber test vehicle (GM sold the car as salvage and required the yard to video tape the car being cut up). This went into my 96' Z71 and I used all the corvette assessories except the AC compressor. I used an F body compressor with a fabricated bracket. The second was a 96' F body LT1 into an 83' Cutlass Supreme. We adjusted the frame rail with a BFH for the AC compressor and used all F body accessories. Both set ups used Accel engine management kits on them (expensive). If I had to do it again, I would use the factory ECM and harness.

If you are wanting to do a fuel injected swap on that budget, you need to stick with the LT1 swap :idea: The initial cost of the engine / transmission / computer / wiring will be about half the cost of the LSx swap

Did you ever finish this project? I have an Lt1 that I want to drop into my 1979 Monte carlo, im wondering what can be swaped from the 96Impala? Breaks, drop spindles, rear diff???

 

[bigdan]

I went carb version ...... GMPP intake + regular distributor solves it ....

I`ve put the spindles + brakes from the impala on the cutlass ...GREAT for dirt cheap .....no bumpsteer at all

i put some bell lowered springs ....+ EMI straight tubular A-arms ..... geometry is right on !

the car handles real good , brakes are great also ......

diff is too wide ....I went ford 9" from a granada same width ! and the looks !
