Thunderbolt engine replacement

[Crazzy]

Back when I was working, we had our own fleet mechanic’s. We used to use the some of these for engine and transmission replacement. They are in Houston area. 1. Texon expensive but good work.2.Drivers Auto Repair in Pearland. 3. Texas Motor Exchange 4. Engine Rebuild.

Thanks for the information.

Run.. I had one rebuilt by them years ago and it didn't last long. If I remember right, about 6 months. Had to rip the motor out again and have it rebuilt by another shop

I'm looking into Texon now.

Ok,
there is definitely mixed reviews.

I got the quote from Thunderbolt at $4995

Quote from Texon Motors at $6150

Quote from 2 Jasper installers at $10,000

All 3 quotes are engine and install.

Makes the decision pretty hard.

I feel your pain.

I've always heard good stuff about both Thunderbolt and Jasper. I actually bought a rebuilt 350 from Jasper in 2003 and it lasted a long time, but dang it was expensive. And about 11 years ago I was looking to replace a 4.7 in a 2000 Tundra and the Jasper quote was so high as to be ridiculous.

My 2002 Sierra is at 290k, been looking into options. Would just buy a crate motor, but I guess covid screwed that up, cant find one anywhere. As others have said, I have heard Jasper is good, but $10k is stupid

Havent rebuilt one myself in a long time, but looks like I may have to again unless crate motors come available again
