Almost impossible. I use a long wrench and try to get them close as I can. After making several tools (that broke or didn't work) it's much easier to use the wrench.

500 Shot of Nitrous and I have not had a problem.

I'd roll the engine on the stand so that it's not wanting to fall off. Basically where the deck surface is 90* to the floor. To torque them, I have an attachment (basically a box end wrench) for a torque wrench to get in there. MAC sells them for about $50 a set.

Snap on makes a torque adapter for this type of situation. Here is an example of what I use for tight spaces. The one thing to remember is ALWAYS torque with a set up like this at a 90°. This will keep your torque to the proper level vs. straight on. If you must use a straight on approach, there is a formula for that. In other words, straight on will multiply your torque depending on how long your extension is. So be careful when torquing things in the straight position.
Good luck...

I took a wrench, cut it in 1/2 and rounded the 12 point end so the walls were thin. Welded a socket on the wrench to attach a torque wrench.

Bingo, thats exactly what I was talking about. I always used it straight out with the formula provided, as 90* always felt akward. Aftermarket BBC blocks use the same thing on their extra head studs.

Yup, sounds like that was what you were looking for. Not too many people think about keeping it at 90° when torquing either. I've seen many shops just say "Oh it's torqued" well in reality it's over torqued. Anyways, hope that helped you out.
