Guest Posted January 27, 2001 Share Posted January 27, 2001 Finishing up the restoration of the drive train on my 65 post GS. 401 ST300/switch-pitch. I am debating on gears. Looking for quick 0-60 and best 1/4 time possible. Would be curious about anyones experience with a similar setup and the the gears that were used.What worked best? My car came with 308's. Thanks for any advice. Link to comment Share on other sites More sharing options...
The Old Guy Posted January 27, 2001 Share Posted January 27, 2001 If you are not worried about highway driving , you should go with a 3.90 axle ,as this will get you through the 1/4 . Any more gear ,and you will probably run out of RPMs before you hit the traps. Link to comment Share on other sites More sharing options...
Guest Posted January 30, 2001 Share Posted January 30, 2001 I think something in the area of 3.60 would be plenty gear for a low reving high torque engine like your 401.<BR> My opinion is based on the magazine reports that a 3.60 geared '70 GSX 455 was a tenth of a second faster than a 4.10 geared '70 Chevelle SS 454. Of course it was a different Buick engine, but I think the philosophy still holds.<P>Tomsriv<BR>'71 Riviera Link to comment Share on other sites More sharing options...
