Re: 1970 12 Bolt "O" Detroit Truetrac

I am sure you could... But the support of the flange is critical to defection under loads of the pinion trying to drive the carrier round and round. and the ring gear can only have so much removed also as you have to get the bolts into the ring deep enough for good retention also. Jim Then the cost ...

Re: 1970 12 Bolt "O" Detroit Truetrac

No , you can not do any aftermarket unit for a 2.56 or a 2.78 gear in a 12 bolt olds. NO one makes the correct offset. 8.5 offset is for the 3.08 3.23 gear set in the 12 bolt olds conversion. :( Sorry.

Re: how to get the most from your motor...

Yes, but also think about if you do find a 2.93 the RPMs will move up some too. That is your call but yes 2200 with 2.56 and freeway driving will be fine. If you ever want to upgrade do a tranny cooler it helps too especially if your switch your mind and do the 2400-2500 stall. :) Just measure diago...

Re: how to get the most from your motor...

do not go too high as the freeway will over heat your trans as it will not fully lock ... 2000- 2500 that is it. with 2.56 or 2.93 gearing Jim

Re: how to get the most from your motor...

cam seems to be right in the wheel house of working with your combo. 1800 - 5000 so if you stall in the 2000-2500 range it will pep up nicely So I definitely start with a easy swap of a stall converter which will make a great difference out of the hole with that camshaft. Timing should always be fig...

The upper control arm mounts are the hardest thing to get around and cause all the issues of an interchange. We had Ideas of making custom r...

Re: 1965 Pontiac tempest 8.2 10 bolt

Yes I will pm you. remember a ring gear spacr with out the longer bolts is bad news. ALWAYS get the longer bolt kits or used correct bolts that go with the spacer.
