I have an 81 4-door Zephyr sitting around, too. I had some absurd build planned but have decided to go EXTREME sleeper turbo setup.

I have a spreadsheet with pricing for every last hose, fitting, and bracket to do a 9-second build on a $5k budget (including the cost of the car).
You have a time frame on when you might have this running? I'm going to be watching carefully lol.

krazy4 05-03-2018 02:28 PM

4.8s are awesome too!

What cam are you going to throw in it?

Sloppy stage 2 should fit the bill nicely. What are the plans for the rear end?

this rear already has a 3.08 rear gear. So ima leave that in there.
I will either change the center section to a 31 spline from a explorer or do a spool, still not sure what I wana do with that.

But the axles will be upgraded forsure.
