Reply to "Driveline vibration after lowering car?"

A few Pantera owners have adapted big-block Fords & 454 Chevys to the Pantera, and because that's a longer block, the whole powertrain is shoved backward some 4" to get the block out of the cabin. The ZF is back so far in such Panteras, the AC evaporator in back must be relocated for clearance. Such cars have run the Silver State Open Road races in NV and the famous standing-mile acceleration events- first at Maxton, N.Carolina, then recently at the Mojave Airport in S. CA.

One of the faster Panteras at Mojave at around 158 mph avg over the mile was Darryl Johnson's 545 cubic inch car in 2016 (?). Jr Wilson was famous in the '80s-'90s with his bored & stroked Boss 429 in a Pantera w/just under 900 bhp. That car was clocked at many SS events at well over 220 mph for the 92 mile long event, and the longitudinal u-joint angularity from the relocated powertrains in all these cars was nowhere near 'ideal'. I guarantee, those big-block cars are pumping far more torque thru their tires than your machine! Your moderately lowered car has a vertical angularity into the u-joints that should theoretically have the same relative effect. So based on the many successful big block conversions, I think Hooke type u-joint angularity as you describe it will be a non-problem for your Pantera, except maybe at LeMans or other long duration pro races. Excessive lowering in front can cause severe handling problems unless 'other things' are done, but IMHO the amount you've lowered your car should be undetectable on the street & give good stock u-joint life. Do not overthink the problem.
