[regalonbags]

im lost when it comes to putting this motor in my car! i have a 97 lt1 with the good heads and about 10.000 onit .it a jasper rebulid. does any one know if they make a plug and play harness for this ? and where i can get it ? and what a good transmission is to run with this motor or which one will work good on it ? thanks for your help

keep searching there are some good write ups on the lt1 swap. i think people are using a separate Painless harness. as for a transmission i would go with the 4l60e they came with.

You can modify the factory lt1 wiring to work, or yes painless should make a kit. Don't forget you will need to drop the gas tank and put in a high pressure fuel pump. I 2nd the 4l60e.

thanks for your help but ive got more ?s why the 4l60e ? doesnt that take a computer to run? should i stick with the stock water pump or go electric ?and i dont have to do emissions so can i block off the egr? once agin thanks for your help

It's a 4 speed overdrive with lockup, has good ratios, will be good on gas, and can be tuned with a computer. Yes you need a computer to run the trans but so does your engine. If you get a PCM from a lt1 car with auto trans it's pretty much plug and play. If you block off the EGR you will have to eliminate the EGR from the PCM also, or it will not run to it's best and will set a check engine light.

I will also add that you should use the baffled gas tank from a 4.3 TBI car or a Turbo Regal as the electric in tank pump does not like to run dry as it would with fuel slosh.

The EGR doesn't really hurt performance in most cases, so I would just keep it. However, you may run into an issue with the chipped key used in stock LT1 applications. It acts as an immobilizer and the ECU will not run the car without it.

I remember in an old Car Craft issue they put an LT1 in a Malibu. I found a link, don't know if it might help you somehow.

there was a guy a guy on ebay for awhile that if you sent him your harness and computer he would send it back to you as a stand alone harness and he would reprogram the computer to be stand alopne also for like 200 bucks. here is a guy that will do the harness for 250 and the chip for 100. i am planning the same swap for my cutlass in the near future.
