my 67 was originally an i6. i think the rearend is 52" or so, backing plate to backing plate. i'm going to put some 06 bullits on there and upgrade to an 8 or 9" rear end. now, i'm assuming i can get a longer rearend to compensate for the backspacing that my wheels will require? anyone know what that rear end may come out of, or at least how long it will have to be?

 

I think the easiest thing to do would be to give a place the Currie Enterprises a call. They could then custom build what you need. You may want to find out what the backspacing is for your wheels before calling.

You'll also want to know the dimensions between your rear fenders, and rear inner fenders.

With all these measurements, you'll be able to get a rearend that will center the wheels in the wells and look just right.

The problem will be with the spring perch location, which is a measurement requirement based on the center of the car. A wider rear will likely have the spring perches farther out than you want.

 

well that would certainly do the trick, but i was hoping to not spend some outrageous price for a few extra inches. this will be a junkyard purchase.

 

once the rear is in, try your new wheels. a 1.5" billet spacer may be all you need.

On another note, why are you using a stock intake with 24# injectors and twisted wedge heads with such a small cam? Unless you have some good reason, I would go with a gt-40/explorer intake and at least a .500" lift cam. That stock intake will fall flat on its face by 5,000 rpm and the stock 19# injectors will work fine and probly give better throttle response and mileage.

 

b/c it will soon have a trickflow intake system on it. the stock stuff is just to get it running. and the cam really isn't that small. this will be daily driven for the most part.

 

With a 9" and 1.5" spacer you will need a 5.5" backspace on th wheel. Any thing larger than a 5.5 you'll get a front wheeldrive looking rim

 

That is a mild cam. Good for drivability (motion), but not really that strong. You'll have no problems having a stock like idle, and you most likely won't hear any loping.

 

bingo

 

Since you're going to upgrade anyway that will work. Be sure you get the backspacing on the wheels you want first.
