Im looking to make my cheyenne a autocross truck on a budget. It has a 305 with a 4 speed. I have ordered drop spindles and lowering blocks for the rear, need to get sway bars for front and rear.. need some advice on modifications.
Should i stay with stock control arms and get polyurethane ball joints???

Read the ruleset for sure. Pick a class, and build for the class. Unless you just want to have fun, in which case do what you want - just be prepared to be uncompetitive.

I ran H/Stock in an '86 Civic.

Then F/SP in a '94 Sentra.

Then D/Mod in a Super 7.

My truck will likely be E/Mod because of suspension and frame modifications.

You have another vehicle to drive?
Kill weight wherever possible. The widest tires you can run with a 200tw rating or higher and a muncie for good gear spread and engine braking. 3:55-4:11 gearing should do most tracks. Getting it as low as possible with some really good shocks and moderate susp mods and you will have fun.

Lowering blocks won't work on these trucks, unless you've already flipped the rear. But even then I'd never run a block with a flip kit.
