They are not all the same.

Now there will be 20 posts about what is different about them.

Forgive me, GM transmissions are not my strong suite lol

Indeed you're right, its been too long since ive done much with the autos.

Re: 84 Z28 LT1 Swap

Well.. It has been a while since I have been able to do anything to the car(money issues

) but, I have since landed a new job, so its back on track!

Update: Heads are in the shop currently getting cleaned up, new stainless valves, and a 3-angle valve job. The old valves were ate up pretty bad :/ Luckily the heads are in great shape!
Finally made a choice of cam.. going to go with the LT4 Hotcam for now.
Got the crankshaft and pistons/rods in. looks pretty sweet. especially with all those ARP fasteners
