Would you use something other than Terminator if you were starting from scratch?

**1957 Chief** · 11-19-2022, 12:17 PM

Yes and no brother. I have used Terminators on quite a few LS swaps and have had zero issues. And I have two builds right now that I will use it.

However if I was to swap an LT engine into something else, I would not use the Terminator. Holley makes some good stuff, but they are missed the mark on this when they put it out for the masses. More to follow I'm sure....

What other options are available for Non stock LT based swaps? Motec?

That's too bad. Although, it's a bit of a relief for me since I'm just doing an LQ4 4L80 swap. Just about to order the Terminator X Max for it.

Quite a few out there. Speartech, HP tuners and a host of folks making harnesses now.

Im no expert...but say in the context of a swap consisting of a late model LT (say an L83) being mated with a 4L75e...what other oltions are there? Key info to consider "Im mo expert"

It's becoming the swap of choice as you can't hardly find a low mileage LS motor any more. I'm getting ready to be done with my first one (L86/8L90 in a 93 SWB). There was a steep learning curve at first, but I think I can knock out my 84 pretty quickly when I start it next.

Hit the nail on the head with that one Rob...jus not many low mile LS motors out there. And the aftermarket companies are starting to catch up to the LT game.
Well except one company.......

Just wanted to give some updates on Sandy, and what she is up to now a days. She currently lives in Mississippi and is a daily driver just about every day that it doesn't rain. Lots of miles have been put on her and after the earlier hiccups with the Holley Terminator, she is still a blast to drive, so much that I tried to buy her from my buddy

Anyways she is back in the shop to get an LT4 blower installed. I put a bigger motor in my C10 and my he just didn't like the fact that I had more "smash" than him, so he said to make it happen.

So going from an LT1 to an LT4 isn't as easy as the internet makes it out to be. But I'm making it happen. With the blower you have to pretty much change everything under the hood except the short block. Heads were pulled off to get freshened up and the blower mount holes drilled/tapped. High and low press fuel pumps, injectors, and fuel lines needed to be changed. I installed a Holley accessory drive which has the dedicated blower belt, a heat exchanger/pump and coolant tank, Improved racing oil cooler, boost controller, more relays, upgraded wiring and a bunch of other stuff. Truck is running out of room to put stuff.

Anyways here are a few pics of the process. Hope to have it running later this week so we can test it at an SCCA event in August, over in MS.
