For the power level you are apparently looking for, I would just keep it "Factory" relative to suspension. By that, I mean simply set it up the same as the 1971 with 429CJ/SCJ. Remember, the 460 is nothing but a 429 with a "stroked" crankshaft.

Most of what you need, you might already have and for the items you don't have, they are readily available.

Just a thought!

Springs,1 1/8" front sway bar, subframe connectors and the best shocks you can afford are the basics.

73 conv. 460, D0VE large valve heads, Performer RPM manifold, Voodoo 227/233 cam, Holley 950 HP carb, C6 trans, 3.25 trak-loc.

Install high durometer front spring eye bushings (Eaton spring). Build an adjustable pinion snubber, a good pair of 50/50 shocks (or adjustable if budget permits), add 2 spring bands to the front half of each spring. It is cheap and it works well. Chuck

If you have access to a tubing bender, take a look at the maier racing connectors. I am going to pattern mine after them. I'm also tying mine into the Convertible brace in the center of the car.

Future plans; JGC steering box, Cobra brakes and... paint, interior, etc.

Unless the springs are rusted to the point of being mechanically compromised, use the money to buy the other parts. Besides the only springs I've seen that actually yield proper ride height and look close to stock are from Eaton spring. They still make springs from original drawings and specifications from the OEMs that account for things such as different engines size and AC. Two jobs, college, and working on cool old cars. You gotta be a real car guy. Keep up your strength and determination. Good Luck, Chuck

when i mostly cruised the street with my 460, i used 620 coil springs and firm ride shocks all the way around. in the rear i used 5 leaf spring. i also upgraded the front swaybar to a 1 1/8 and the rear to a factory 1/2.

now that i'm more into drag racing and limited street use, i went to stock 73 springs for the suspension travel and left the stiff rear leaf springs in the rear. i now use adjustable drag shocks all around for the front lift on take off. i took out the rear swaybar for bigger wheel fitment (don't feel a single difference with or without it) and temporarily i have the front sway bar completely removed. i will reattach it on the street but i will soon build some kind of bracket to where i can just disconnect the end links and safety wire them up at the track. got to figure something out on that.

if you need a 460 motor from carb to pan, i've got one available along with all the parts for the c6 trans to the actual c6 trans itself. PM me if you've interested

thanks for the advice and motivation. i can say im a true car nut not many of my friends around my age (21) have very little interest in the old cars, i love em not only do i have 4 cars, i have my basemnt garage and even attic full of my parts etc, i have 3 motors 2 trans between my house and my brothers garage lol my parents just love it ha ha(not) but they support what i do, im lucky to have two good older friends who are car nuts with one having a 72 coupe and conv so i have some knowledge if i get stuck
as far as the springs go ill haveta clean them up and see how the look i think they will be ok to use still i just want to put my money in areas that will be effective, not wasting it on things i dont necessarily need, once i get out of school mods will def come. the car will be 99% street driven and taken to local shows.
thanks for the offer on the 460 i actually have two onbe form a 69 lincoln(the good one) and one from a 77 lincoln and one c6 !
