Default 1974 Opel Manta LS swap

The pics are kind of random due to how I uploaded em.

Some quick info on the car. It's a Belgian made car, found it by chance a few blocks from my house. They originally came with an inline 4 cyl, 4 speed and weighed about 2180 pounds showroom stock. It had power discs in the front, a 3 link type rear suspension and f/r sway bars. I did EXTENSIVE mods to get the current combo in it. 4 months of 60 hrs a week in the garage trying to make drag week 14'. We finished the car the night before and it literally had 80 miles on it before driving it from KC to Tulsa. It was untuned and untested. Even with the tall gears and 2 speed transmission it went 12.3 and got 20 mpg avg for the week. With the exception of a couple of sensors swaps we didn't turn a wrench on it all week. Big thanks to my Friend Joey Grier for his tuning help and Collin Williams for all the labor and fab work. It has a narrowed 8.8 with all the good stuff from strange in it. We had to narrow it 12.5 inches to get it under the car. We also converted the rear suspension to a torque arm set up. The motor is a stock 04 5.3 short block, ported/polished and milled 241's with BTR valve train, ported LS2 intake, ported Edelbrock TB and custom exhaust. The glide has a tranny brake, manual valve body and a TCI 3400 stall. I'm running 235/50/15 M/T drag radials in the back. It's got Strange double adjustable coil overs in the front and strange single adj shocks in the rear on stock springs
Car was originally going to be a cam/heads NOS car which is why I went with the glide. I had 3.08 gears in when I competed at drag week but since I didn't have time to get the cage in it I scrapped the NOS due to the safety rules. I've since put in 4.10's in anticipation of my new mods coming early spring. I'm pulling the glide and going with a 200R4 and adding more cubes as well. The cage will go in once all the motor/tranny stuff is finished. Car currently is an easy 11.50 time slip. After the new mods my goal is mid 10's. It weighs about 2500 with me in it.

Love the car, love the color. The shades of green that were popular in the late 60's through 70's are cool.

Thanks for the pics. I do remember chatting with you at Great bend 10 dropped. Just wish I would have had my car dialed in. I would have been way more competitive.

I think most of the pics I've taken are in my photobucket albums.

Update. Swapping out the glide for a 200R4 and changing the cam to something that will perform better with the manifolds. Should be in the 10's on motor by spring.
