Another way to skin the cat; the High Torque 292 LS swap

[lt155ruck]

[QUOTE=dayj1;7147162]

I've had this taking up room in my shop for the last year or so waiting on the right vehicle to come along for a swap:



It's the "littlest" LS; a 4.8. Since 4.8L converts to 292.9 cubic inches, I decided to round down and call this a 292 swap

The 4.8 came from a 79K mile 2003 Tahoe. I bought it over a year ago and slowly gathered parts. It's got a mish-mash of truck and Camaro parts for the accessory drive and a LS1 'vette intake

Very cool build! Can you explain the mish mash of truck and Camaro parts of the Acc drive? Maybe what is from what or part numbers? Or what you did to make it work? the water pump looks like the l99 part number 19207665? Thanks in advance

Thanks!

I had actually written all that up for a guy on the trifive board (notice my '57 BelAir behind the completed engine in the last pic). So, I cut and pasted from my post over there...

Wow, thanks for that..that's even more comprehensive than I expected. That's awesome. Lol but you did forget to mention what belt you used... What are the details on your 57?

You're welcome! The belt is 79.5". The Gates number for that belt would be K060790.

As for the '57, I've had it since '99. It's all stock except the wheels and the drivetrain. It was my second LS swap. It has a 5.3 with a Radix blower running 11 psi. HP/TQ is about 450/490 to the rear wheels.

Nice, that is sexy. I'm guessing you surprise more than a few people. Funny how we seem to hold onto things. I've had my 55 since 97.
