Performance?

Definitely performance oriented. The stock frame works for cruising so aftermarket support isn't required which makes recouping your investment harder.

Stance? - Fixed or adjustable (Air Ride)

Like everything, different strokes for different folks. Offer a set-up that can easily accomodate either (coil-overs or Shock Waves). One set-up means less fab work for you which reduces overall costs for the end consumer.

Price?

Highly subjective. Obviously if you can bring something to market thats more perf oriented than your market competition (Jim Meyers offers a full replacement frame for example) the price can be higher. But, the economy still has a tight grip on many peoples accounts.

Ease of Installation?

Keep It Stupid Simple. Unbolt the cab, doghouse & bed. Swap 'em to the 'new' frame (maybe only requiring bed floor mods & new front inner wells).

Levels of completion?

Guys w/trucks want to play in the sandbox w/the rest of you w/cars & then haul everyones stuff back to the shop . Offer bare frame's to a complete rolling chassis.

Strength? Appearance and Quality?

Again subjective. A guy w/deep pockets doesn't need a readily available truck chassis..... he can have someone build whatever he wants. I've also seen frames that are a work of art (like RadRides newest p.ject) & I'm sure they're priced like art. While thats cool, it's priced out of most peoples budget.
Strong, simple, & solid. A foundation that corrects all the 37+ year old OE engineering.

Any serious input would be greatly appreciated.

Remember, remember . . ..... remember...... It's a truck first & foremost. Don't eliminate that while engineering your improvements.

I've played w/GM trucks since back in the mid 80's & have tweaked more than a couple of my own. My current stash consists of a 64, 67, & a 74. My current projects include the 64 w/an aftermarket Porterbuilt C10 front c.member + tweaked rear truck arm set-up (currently performing some rear frame mods on a spare frame) & my 67 w/another Porterbuilt c.member set-up (this one has a C4/ShockWave set-up w/a BBC/4l80e). My 74 is just dropped factory set-up w/homemade built AOL to maintain it's ability to still be a truck.
