My dad has recently started racing a vintage stock car in a local vintage group. I have been going to help him and I want to join in on the fun. I started putting together a car out of parts I have left over from other projects. I have a 65 f100 frame that I have swapped the front I-beams from a 77 f100 onto in order to get disc brakes and power steering. I am going to run a 300 and already have it mounted. I currently have an aussie speed 2v intake, 500 cfm 2v holley, pertronix ignition, and headers on the motor. mated to a stock style 3 speed with an old hurst floor conversion. For a body i am going to drop an old nash statesman body over the frame and cage. The class does not allow trucks. Rear is a stock 9in.
I know that running twin i beam for a circle track car is unconventional, but I want to spend as little money as possible and just run for fun. I don't mind running at the back of the pack as long as i can get it to work halfway decent.
Any one have any suggestions on how to go about getting the truck chassis to handle halfway? i can copy the suspension set up from my dads 57 Ford that he is racing but the front geometry is a complete different animal.
And sorry, use something else is not an option. Part of this whole scheme is to find out what twin i beams can do. If its a complete failure down the line i can crown vic subframe it, but i really want to make the twin i beam work. I like different.
I could also use suggestions for a good, but affordable cam that will wake the 300 up beyond the stock grind.
The problem you face with the "I" beam front suspension is a tremendous amount of un-sprung weight and constantly changing camber that's going to be different between the left and right wheels. Adding a front stabilizer bar will help with the camber issue while helping to keep both wheels kinda pointed the same direction. The only problem with that is a front sway bar will increase the tendency to under steer to counter that you also need a rear sway bar to add some over steer and balance things out. Front sway bars were available from Ford 75-79 rear sway bars were available on the big Broncos.
Here is a thread to look at Stock 2WD front sway bar dimensions - Ford Truck Enthusiasts Forums
I have a front sway bar on my 65 from a 78 F350 and it greatly improved the stability and ride quality for a street driven truck.
As far as a cam lots of companies grind cams for a 300 I6. Just try to figure out what RPM you will be at coming out of the corners and find a cam that will produce a lot of torque at that point.
Good Luck
