I have been doing some head scratching lately. Every time I look at my
1985 Trans Am I keep thinking about transmissions.
At one time I was going to go manuial with it, yet I just haven't found
a 4th gen parts car yet. Then I thought about going to a 4L60E. Then I
though, why? It's no stronger then the TH700R4 I currently have. Then I
thought 4L80E, with some sort of stand alone transmission controller,
Since Im not going TPI after all.
As for WHY do I need a better transmission? Im going to be adding a few
power goodies like the old Holley Street Dominator (now they call it a
Contender) Intake, a Holley 4150 style 770 CFM Carb, possibly a new Cam
(one I run the number off the current cam). I may also upgade to Dart
Iron Heads off our 383, since no one has bought the engine, and slap my
GM heads on it. Plus Im getting the hankering for a blue bottle in the
hatch area too.
So concivibly Im looking to add from 100 to 350 HP (with N02 spray).
Kind a bit much for a old TH700R4.
Is Mustang Hunting Still Legal?
