Upgraded Suspension
(circa 1990)
NOT a “Drag” car; more aimed at “Road Rallying”.
I upgraded the suspension way before coilovers and tubular control arms became fashionable.
Click the link to see the details, but basically,
- Taller spindles now provide a negative camber curve to raise the roll center from below road level to ≈2″ above ground level.
- Poly bushings and larger anti-sway bars were added too.
Upgraded Steering (twice).

Configuration | Ratio | Travel |
---|---|---|
Original | 17.5:1 | 87° (±43°30′) |
In the early 90’s, I added a mid-80’s, “fast-ratio”, Trans-Am Steering Box This required a special “rag joint” and fittings. | 12.7:1 | 70° (±35°00′) |
In late 2020 I added a mid-to-late-90’s Grand Cherokee Steering Box. It has the longer travel. | 12.7:1 | 87.5° (±43°45′) |
Wheels / Tires
- O/E Stock was:
- Standard = 7.35 x 14 on 14″x5″
- Hi hp 327 = 7.75 x 14
- Chevelle “SS” = F70 x 14 on 14″x6″
- Standard = 7.35 x 14 on 14″x5″
- Front
- Were 235/60R15 on 15″x7″ Rally Wheels
- Now:
- Wheels = Cragar Series 380S Rally II 17″ x 8″ (Jegs) p/n = 1722373537
- Tires = 235/45ZR17 Continental ExtremeContact Sport
- Rear

- Tires = 255/45ZR17 Continental ExtremeContact Sport

Front Disc Brakes (Powered)
By using the spindles from the ’73 during the suspension upgrade, the front disc brakes easily came too.
The power booster is from a ’70(?) Chevelle.

Holley Sniper 2 EFI

Sniper 2 EFI is the second-generation EFI conversion for common 4-barrel (4150 flange) style carburetors. It is self-tuning and easy-to-install.
The main harness includes support for plug-and-play installation of a HyperSpark distributor and ignition module for integrated timing control.
Using the Holley In-Tank Fuel Pump Module

No need for a return line with this in-tank fuel pump / sending unit module made specifically for putting EFI on a 1964-1967 Chevelle. Rated at 255 l/h, it supports up to 550 horsepower.
I was able to install it without dropping the tank.
