I started my build table and frame about a month ago. I had been collecting parts for another project when I came across this site. I had always wanted a 7 but the kits were out of my reach.
I have a 3800 from a 96 Camaro, a t5 from a 89 T-Bird and a disc brake rear end from a 98 s10 Blazer.
I'm sure I will have a lot of questions in the future, this forum is a wealth of knowledge.

Make sure you measure that rear end to fit, a lot of the S10 rear ends are just a hair to short to use in a +442e frame (It was originally the rear end I was planning on using).

What is the width of the "e"? I'm building a 442 which is 46" and the rear from a 96 Bravada is just about right at 59 3/4.

It is 4 in. wider along the whole frame it is 46 at the rear also. The rear is out of a 4x4 Blazer, should be the same as yours.

The 442E is 4 inches wider, 4 inches longer, and 2 inches taller than "the book" overall (as indicated above)... and unlike the "442"... the extra 4 inch width was applied throughout... requiring a "wider than the book" nosecone.

As for choosing a chassis width and/or rear axle width... I always recommend mounting your intended wheels and tires on the rear axle, then measure the distance between the inside of the tires. I rarely consider flange-to-flange measures because they don't mean much to a given build without some knowledge of the wheel and tire geometry. Anyway... I propose at least 1.5 inches of clearance on each side (between the rubber tire and the steel chassis)... 2 inches on each side to be comfortable. So with a 442 (or 442E) at 46 inches wide... you want to shoot for a tire-to-tire measure of about 50 inches.

I'm sure it goes without saying, but different wheel offset or wheel spacers can be used to give more clearance (I just started following these threads after a long break, so I'm sure to repeat a lot of common knowledge). You'll want to layout the front lower control arms to at least match the rear track width.

Cheers,
Jim M.

PS - Is anyone interested in a "332" or "322" chassis?... to better fit rear axles like the S-10 or the Miata stock width (from what I've heard). My personal build is 45 inches in the rear to better fit the 1st Gen. RX7.... just wondering if there is interest.

I got most of the bracing done this weekend and started on the trans tunnel.

Not much progress this week, started final welding the frame. I went to my home town and picked up my engine and rear end. It was missing a rotor and caliper bracket, but the price was right. Rock auto has them cheap.

I started mocking up the rear suspension. Is it better to have the panhard bar parallel to the axle or is an angle to clear the diff cover
alright ?

The bar needs to be as long as possible and horizontal. It needs to be straight because it will be stiffer, so offset the brackets from the diff as necessary for a long, straight, horizontal bar to clear through the range of suspension travel, one wheel bumps, and body roll.
