Default 65 mustang fastback suspension

Hello all,

I am doing a full resto of my 65 mustang fastback. I have stripped it down completely and i am about to fix a few rust spots in the floor.

My question is that I am planning on putting a 363 ci motor in this thing but will mostly be doing street driving. I want it to handle well but i want to make sure i don't put too much or too little. I would like it to handle corners well but still maintain a good ride quality. I was thinking of this kit at Mustang Depot: Ultra Suspension Rebuild Kit - 1965-73 Mustangs from Mustang Depot with the stage 3 setup with the maier race 165 rear leaf springs.

I am definitely changing out the stock 8" for a 9" rear housing to handle the close to 500 horsepower i will be putting in it with the 363.

I would also like anyone's comments or experiences with the 363 as well since i have not bought the materials to build one yet but i am wanting about 500 horsepower. Thank you guys.

The kit you posted a link to has 700# big block front coils. I assume your 363 is a small block based stroker motor. Those springs are way too much for a small block car. I used the same kit for my 67 with a 347 stroker. My front coils are 620# and are way too stiff. The rear sway bar is over kill. I would do the shelby drop, with your stock coils. A 1 inch front sway bar, no rear sway bar and GR2 KYB shocks. Roller spring perches and roller idler arm are nice to haves also. My car rides like a truck. I have driven it without the seatbelts and had my head hit the ceiling on bumps.

Yes the motor will be based off a DART 302 block. Still trying to look at a 347 but will probably go with a 363. I am looking at doing the progressive spring option with the GR2 KYB shocks. I was wondering about the ride if the Race 165 was going to be too stiff but i am wanting to have a little fun from time to time. Do you feel or see any lateral movements of the rear end with out the sway bar? I am definitely lowering the upper control arm, plus the tcp has a mounting block that does it without having to drill more holes.
