K frame lowering blocks

I've run spacers between the K frame and frame rails since 1982...they aren't 'dropping' the K frame, they're raising the car.

I only use 1/2" thick, nothing thicker.

The torsion bar misalignment is meaningless. I could go into a lot of explanation on that...but I'll just say it is no issue. Same goes for the steering column alignment.

If you don't believe me, just go look under a Chevy truck and you'll see T-bar misalignment that'll make you puke.

The real concern is suspension geometry. That's because when you drop the K frame, you are adding to the 'spread' of the LCA/UCA pivot points without adding to the spread of their ball joint points.

The good news is 1/2" seems to make no difference, in either alignment or driving.

This mod offers a lot of clearance in a some important places. The most important is hood clearance...a dropped base air cleaner is often easier said than done, and usually results in other stuff getting hit like the kickdown linkage or float bowl, etc.

So with the spacers, I was able to run a 440 (RB) with a Torker intake, Holley 800, and the usual cheap 14" air cleaner. All of it fit under the hood....nothing worse than holes in hoods.

I also now run a 499" (B) engine with M1 intake and 4500 Dominator, again all under the same hood.

But would I use a 1" spacer? Hell no.
