Guest Anonymous Posted July 29, 2003 Share Posted July 29, 2003 I just picked up a very nice Toploader 4-speed, tag #HEH-CL (used in '66 Fairlane 390GT). I'm looking to build a 302-powered Z with a manual trans. Engine will be fairly mild, probably under 300HP. Am I better off keeping the bulletproof Toploader or going with the overdrive-equipped T-5? I asssume I can sell it to a Fairlane guy for enough to get a good T-5. Quote Link to comment Share on other sites More sharing options...
74_5.0L_Z Posted July 29, 2003 Share Posted July 29, 2003 If you are going to keep power below 350 hp, and if you are going to drive on the street, definately go with the T5. The Z has to use a fairly short tire ~24.7 for 245/50/15, and high ration gears are hard to come by (3.36 is hard to find, 3.545 is more common). Without overdrive, using a 3.545 gear, 6200 rpm in 4th is 128 MPH, and 2900 rpm is 60 mph. With 0.68 overdrive gear 5000 rpm is 152 mph, and 2900 rpm is 88 mph. Sell the top-loader get the T5.

Guest Anonymous Posted July 29, 2003 Share Posted July 29, 2003 Yeah, think I will get a T5. I'd need to get a bellhousing and shifter for the Toploader, anyway... it's just that I have it right now and it looks so pretty... Quote Link to comment Share on other sites More sharing options...
