v8 swap to LSX upgrade

503 Views 6 Replies 6 Participants Last post by  MtnMan4x
Hey gang, not sure if this goes in the LSX discussion, but I have a 95 2door 2wd Blazer that already has an iron headed LT-1 with t-56 in it. Rear end has been upgraded with 4.10s, Eaton posi and disk brakes. Here is my dilemma, I have a lead on a wrecked C6 with a LSX 454 in it. Frame is unrepairable, auto trans is shot but I'd like to be in it for the motor, brakes and seats. Curious if anyone has taken one that has already been V8 swapped and upgraded to LS platform? Wondering if I'd have to change motor mounts and if the harness swap would be fairly straightforward or would I need to go aftermarket?

Any advice is appreciated!!

Since the engine is from a C6 the mounts should be the same. Wiring is many generations different from the LT-1, which could be obd or obd2 depending on the year. Contact CPW to see what they can do for you. Since your truck is a 95 it's probably been extensively rewired already. Depending on whether the LT-1 is a 92-94, a 95, or a 96.
