Im working on a golf cart, custom suspension front and rear. Originally, the plan was to use a Pred 420, but I would really like to use a 670 if I can. The problem is that there is only 12 inches of height under the seat. How short can I get these engines?

Lower the engine in the chassis. It’s done all the time.
I don't want to sacrifice ground clearance.
A 420, without the muffler and gas tank, is a little under 12 inches high.

You said "custom".
That means nothing will fit and everything will have to be fabricated.

Then don’t. Use taller tires to get your ground clearance back. I used to do it all the time on lifted golfkarts.

Sounds like the 420 with a different exhaust and a remote gas tank is a winner.
In your 1st post you asked " how short can I get one of these engines ". That's not a variable. What ever it is, it is. Why don't you go down to harbor freight and take some measurements of the 670. If it's over the 12" of clearance you currently have, then it's time to make some modifications, or use the 420. Pretty simple. Your kart, your choice. Hope the V-twin fits.

Can confirm.
From what I can find, just the tops of the valve covers of a 670 are about 15" high.

What is stopping you on the top side? Cut a hole, build a dog house.

Can’t, the seat is above the engine.
Lots of golf carts with the 670 engines. The trick is to build (or buy from Vegas carts) a "engine cradle". This bolts to the rear axle and has a pivot at the front. So the engine and transaxle are all one unit. It also sets the engine much lower so there is no interference with the seat/engine space.
I built my own. If you aren't doing a golfcart trans the cradle is still a good idea to lower the drivetrain.

But he doesn’t want to sacrifice ground clearance. And he doesn’t want to raise it up because he’s afraid of heights.

or make a custom one these work well also if it has front and rear suspension how will you tighten the chain if it is underneath your seat go karts that have front and rear suspension use these
