The price of street gas being what it is, even the most hard-core hot rodder must grasp the consequences. Certainly, they can curtail driving to reduce fuel cost, which often precludes traditional destinations and may even cut into appearances at the local drive-in. There is a sensible way to combat this issue, even if it only means a few miles per gallon. Overdriven top gears have been around for many years, mostly at the behest of the OE manufacturers-see, they actually did learn something from the fuel-blank debacles of '73-79. Overdrive automatics became standard equipment a quarter-century ago. It's about time hot rodders got hip to this worthy upgrade. We can't believe anyone would still want to "cruise" with straight 4.56:1 gears.
The abuse the engine suffers at 3,500 droning rpm is a lot more worrisome than one gliding along the high-speed at a sedate two grand. Think how much quieter things will become. Think how much you'll reduce the size of your environmental footprint. The cruel fact is that as much as hot rodders have historically scoffed at the rules and the socially accepted norms of the period, we have to start playing the establishment game, at least to some extent. Here's one way to do it.
Though the notion seems simple enough-replace a transmission with a similar, albeit electronically controlled, one-all is not what it appears to be. Will the bellhousing attachment holes correspond to the ones on the back of the block? Will the driveshaft bolt back in? Is the hardware compatible? Before you begin, seriously consider using new fasteners available from any GM dealer or aftermarket source.

ZZ4 crate motor backed up by my 700r4 transmission with a 2500 stall Corvette torque converter shift kit and what not!.. This was in my 77 Trans Am with 373 gears!.. My car would do about 165 miles an hour in overdrive never ever did click the button to lock the torque converter up because the highway always ran out off long enough straight aways. My buddy was on his CBR 900 street bike to see how fast my car would go. Because it was only registered to do a hundred miles an hour on the speedometer.. And I knew it would go away faster than that!.. And did ever and does it ever still go, its just owned by my friend now
