can it be done without extensive modification to kmember? im new to the truck scene and ive found a 99 rcsb 5speed v6 that i wanna throw a ls1 into further on...any input is appreciated..

 

it will drop right into the 99 pretty easy. If you get the V8 truck FEAD, and intake you will be good to go. The other big issue you will have is a engine harness, the V6 harness will fall short of 2 injectors. If you can find a 9 RCSB with a 4.8 it would be a easier swap IMHO.

 

so it would be alot easier to wire up a ls1 to that 4.8l harness, makes sense....anybody have pictures..

 

If you had a 4.8 truck it is a weekend project to drop an LS1 in.

 

sweet, thanks for the help man....has anyone throw a t56 on top of that? i dont plan on it but im just curious

 

there are a few guys that have done that mod on here....I am sure they will chime in.

 

the V6 to V8 swap can be done in a weekend if you have everything. Although it would be cheaper if you started from a v8.

Cost range for motor swap around 4000-5000 thats not playing around with stock stuff though, this includes tune, headers, mounts, harness modification etc.

cost to do a v8 to v8 swap is around 1500-1700 cheaper if you go with headers tune etc.

If you use stock stuff it can be done for 1500.00

 

sweet...looks more possible now.......

 

thats not including tranny cost through, im clueless on those 5 speeds!

 

Sorry for stealing the thread here. I have a 00 4.8 I would love to drop a 6.0 in. Its an auto trans, and I have the 4l80e tranny. I'm just wondering the extend of the work for the swap and cost.
