I'm thinking I put too small a cam in my 360 Magnum...
I was wondering, I was told that 225 were the best hope with upper arm offset bushings, I erred on the side of caution and got 215 even tho I did the offset bushings
So are you saying that your front tires are 215s?
215 what. Nevermind it doesn't matter.
You need to think this thru.
Are you aware that your 360 with that cam, in your lightweight car, can be doing well over 60 mph in just 5 seconds of WOT. By Eight Seconds she'll be doing close to a hundred mph. And yur depending on 215s on the front and 235s on the back, to get you stopped; with one of the worst handling factory hotrods ever built by Mopar.
Brother, you better have great life insurance..........
SEVEN degrees off axis, and you cannot straighten that car out, Just Seven degrees and the back is coming around.
Even 235s on the front of my short WB Barracuda are not enough tire.
My secret weapon is the 295s on the back running no hydraulic proportioning at all on the back, and a very heavy rear brake bias. When I stomp the brakes, it's like I imagine it would feel like, to throw out a parachute!
If you pulled up to my front door with your Dart, and said "hop in", the first thing I'm gonna do, is to look at that combo of 215/235 and the second thing Ima gonna do, is say, "pass".
If I die/when I die, it's gonna be if I get stuck in the Tribulation, lol.
Ok Now, having said that, I also installed those problem solvers and got IIRC ~7 degrees castor on one side and maybe 6.5 on the other at Zero camber. By the time I got to 3/4* camber She was down to around 3* castor. So I gave back some camber to get some castor. I mighta ended up around 3.5* castor at or just under .5* camber.
Then I ordered some custom offset 5on4, 8x15" Rally wheels. IIRC those were 4.25 bs. And I worked my butt off to make them work. First the wheel weights rubbed, then the BJs were rubbing on the turns. My trusty disc-grinder got a workout that day I'll tell ya. Then when I backed off the Drive-on lift and simultaneously turned and braked, well then the fender got the rub. One by one I solved those problems to fit some sticky 245s....... which were great tires to have around town, but they didn't even last the summer, so back on went the 235s, and I learned to slow down.
The point is that 8x15s will fit up front with a 4" backspace. Should bolt right on.
However, Because the SAI is now in the wrong place, the tires tend to want to follow ruts in the road. So I switched to 7.5 wheels on Zero offset, and that did the trick.
I run the crap outta those 235/60-14 fronts, on those 7.5 x 14 zero offset wheels, with no issues whatsoever. and the bonus is that thy last for thousands of miles.
I just gotta slow down for the turns or, my favorite, steer with the rear tires sliding and on fire, lol.
Now; Mr. James, I apologize if I came off a lil harsh in the beginning, But my smartazzedness goes back 54 years to my first Mopar A-body. I have had at least one on the road for almost all of those years. I even crashed one on my wedding night! and yes, my new bride was in the other bucket.
These cars were never meant to handle 350 hp, never mind 400 or more, they were even lousy with the 275hp 340
At my age of 70 now, I have to depend on my car to not let me kill myself in it, cuz I ain't as quick as I once was.
For the street;
Those 215s have to go. If you need new wheels, well, welcome to HotRodding. I got a shed full of parts that just didn't make the grade.
and
you need to move the back springs over and put the tallest tires in there that will fit, with the widest-treads that will fit, with a minimum clearance to the body of 3/8 inch, and with a minimum of 1>1.25 inches of vertical clearance, depending on your springs and shocks. To the springs can be .25 inch or a hair less, depending on the amount of arch and the bushings used, and your driving style.
Get this done, before you ever drive it, cuz 350/400hp in a lightweight long wb Dart is a cunning recipe for disaster.
At your weight, I would definitely consider ballasting the side to side weight. As it is,
if the alignment was set up NOT with you in it, then it will be DEAD WRONG when you climb into it. It will NEVER steer right, and it will eat tires. and you should look into heavier T-bars. I recommend 1.03s . and the 1/4m race track is gonna hate those; more nitrous!
I used to be an alignment guy, and I figured this out in a hurry.
Again, sorry if I aggravated you.
Thank you for your service.
