Well, decided I should start a spot with all the info for my newest rebuild of my wagon that my old LT nicknamed the Wa-GOON.

it had a 355/200-r4/8.5 for the last few years, also has the 1LE 12” front brake swap.

I found a 6.2 L92 from a Denali, had the heads rebuilt, swapped in an oil pump, and added a BTR ”Red Hot” cam with matching valvetrain. On the top end, I grabbed the FiTech top end kit with the 102mm throttle body.

the transmission got a Yank converter, and a new tail shaft with a mechanical speedo setup.

recently, I decided to do the 14” corvette c5 front brake swap and 12” rear F body swap. I’m going to swap to 18” rims also. Figured I might as well swap to coil overs while I’m in there too

I think I covered it all… if I forgot something, I’ll add it along the way

I wasn’t too satisfied with the throttle brackets available, so my friend made one for me

I wasn’t a fan of the factory power steering line

So i had a local shop make one for me

did the transmission lines with AN

did all the fuel lines in AN as well. Used the Astro fuel sending unit with the corvette regulator

Lowell, MA? That wagon is a nice survivor. Please post details on the mechanical speedo conversion. What are you using as a VSS input to the ECU?

Yes, thats where I grew up, but now live in Tewksbury. I’ve had this wagon about 10 years now, and it only has 52,000 miles on it.

here’s the link to the tail housing I used on the 4L80e


VSS… didn’t think I needed it with the Holley kit… I’ll cross that bridge when I get to wiring😂
 
Beautiful stuff here. I really like the creativity with the fan shroud. You are taking your time, being thorough and it shows.
Underneath it looks like my 442 with all of the added body struts, etc.

You will really like the L92/4L80E setup. Mine is very streetable with DOD delete and a TSP VVT cam, but will get out of hand in a hurry if you aren't paying attention.

Keep up the great work.

I’ve done A LOT of reading getting ready for this. The car had every factory strut/brace except for the GNX back seat brace. I did upgrade the jounce bars to the UMI piece. I also run a 36mm Iroc-z hollow front swaybar, with a herb adams 1-3/8” solid rear swaybar. Waiting to see how all the new suspension upgrades are with handling

I love my turbo 2 door, but wanted something more subtle…

Came home from work to my driveshaft waiting for me. Such a shame that it’s hidden under the car!

Also received the step-down silicone elbow I needed for the air cleaner
