One thing you will have to remember is that the rear springs will need to have the Mark Viii spring perches addeed to it. Do not be afraid to cut the springs. I did a write up on SCCoA a few years ago and have been driving the car since. It works great. The only problem is the front strut mount (to the body) holes need to be lengthened if you go more than an inch and a half.
Soon to have some MHS parts, cams, 'luminum block, lower compression, ported heads, autorotor, and need to make long tubes. I have almost all the stuff and need some #42-50s a bypass valve, and maybe a few other things.
