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.

I have a 95 with a SBC/t-56 in it, I want to switch to an LS..

yes, thousands of people switch out their tired SBC engines for the LS. It's probably the most common swap in the country.

youd need to gather parts, or get a swap in a box from summit and the correct spacer to adapt the ls flywheel to your trans. They might even make one that doesn't need the adapter.
if you runa standalone you can make the motor run very easily.
Some of your gauges might be an issue, but, you probably already have that figured out with your sbc swap.

If it were me, I’d upgrade what you have. A 454 LSx will obviously have more potential, but heads and a cam on a LT1 will make a very fun truck that you can drive again in a weekend. Other than bragging rights, what’s the goal of the truck?

Don’t forget the seats and brakes. If it’s a good deal I’d snatch it up, sell the rest. Exhaust probably still good, rear suspension, rear brakes, etc.

Buy another truck, '98 & up and do the LSX into that one.

Can't have too many!!!!

Definitely on the seats and brakes too. I've thought about going thru the current motor as I've had 400+ hp LT-1s (been a B body guy forever) but aftermarket is kinda drying up for those and I just thought as I'd have the motor out anyways...and a lead on that motor.... just got the wheels turning....
