Options I added:
Front discs
Power trunk release
Rally oil/temp/fuel gage
Bullet mirrors
Power door locks (soon)
Engine:
After spinning a rod bearing several years ago I did a complete performance rebuild of the transmission and engine. Upon tearing down the engine I discovered damage from a previous thrown rod incident. I set the 70 block aside and picked up a 75 455 complete engine from a Lesabre which has better oiling passages and a better casting. From there I had the crank, rods, new forged flat top pistons and aluminum flex plate balanced. Bolted the rotating parts up with ARP hardware, had the 70 heads ported/polished, larger stainless intake/exhaust valves were installed along with roller rockers, 3/8 push rods, dual valve springs, Hi-rev lifters, and a Poston's cam(I don't have the specs, but I think it has a 108 centerline.) An HEI distributor throws spark through 8.5mm Accel wires and then to AC-delco rapid fire plugs. An 850cfm Holley double pump carb supplies the fuel. The exhaust starts with Torque Tech headers with 1-7/8in primaries down to 3.5 collectors blow to a full 3" mandrel bent (w/ X pipe) exhaust system w/ Flow master 40 series delta flow mufflers. A Griffin aluminum 2-core radiator and a heavy duty 80's style Volvo electric fan help keep the beast cool.
Transmission:
The TH-400 received a performance rebuild, a 3000 Hughes stall converter and a heavy duty transmission cooler.
Rear axle:
Rear-end was the stock BOP 10-bolt w/2.93's but was destroyed at the track. I believe the axle was low on gear fluid; Eventually the stock posi disintegrated and a chunk of the side gear went through the center section. I ended up finding a wimpy(and dirt cheap) Chevy 10-bolt w/3.36's and modified the posi for better performance. The Chevy axle is only a temporary fix until I can locate either a 8.5, 12-bolt or a 9".
Suspension:
Suspension consists of all polyurethane bushings, new ball joints, tie rods, and center link. Heavy duty front and rear sway bars and performance rear control arms. 245-50-15 Dunlop GT Qualifiers wrap around the stock 15” rally’s.
What's going on now/future plans:
Currently working on some interior items. I just finished restoring the dash bezel with an oil/temp/fuel rally gage, rebuilt original tack, new wood grain, and did some wiring repairs.
The fastest time in the 1/4 was 12.8 sec. This was done with the Chevy rear and radial tires. I'll try to find the time slip when I get a chance.
Future plans: I need to do some R and R on the transmission to re-seal everything. I have a real bad leak and I believe it's the front seal. I want to pull the engine as well, tear it down for inspection and re-seal. Finally, find an axle as mentioned above. Maybe on some random weekend!!!
