Glad it worked for you! Cheers!

DC, as long as the rear tires can be held from rotating, one CAN determine true stall speed. Of course, a trans brake does this job easier, but unless you have a very high torque output, the method I outlined does work quite well to hold the tires immobile. Bear in mind that no converter...

Did you ever give it another try?

You were on the right track, but can improve your technique to get better results... 1. Position the car on a deserted street or parking lot so that as it moves no one will be in the way. 2. Raise the rpm to a fast idle in neutral to get maximum engine vacuum for the power brakes and press the...

The 3.08 case (3-series) will also work with 3.36, 3.55, and 3.70 gears!

If you already have 3.36s, they will do a respectable job, especially combined with a higher stall torque converter. To illustrate, with a 406 SBC in my '78 and a 10" diameter TC with ~2,800 rpm stall and 3.08 gears (and a Quadrajet!), it ran upper to mid 11s in the quarter! Either a 3.55 or a...

Don, With your cam (238/242 on 112 lsa) you will need the 2800 stall rpm, but I question your comment on hooking the lockup to the brake pedal. There must (should be) some way to prevent the TC from locking when you release the brake pedal to accelerate. Otherwise, the TC won't reach any...

If the rims have less back spacing than stock the rub will be more certain. If you have stock rims, there shouldn't be a problem unless the body has shifted.

It's a 1350 u-joint not a 3150

I believe you're talking about needing a 27 spline yoke for a 1350 u-joint - bear in mind that large 1350 u-joints are not required for the drive shaft but are used with the half shafts. The correct u-joint for the drive shaft should be a 1330 or a 1310, or a conversion u-joint, depending on...

I'd recommend a 3.36 rear end gear ratio. If you multiply the RE gear by the first gear ratio, you should target about 10:1. With a 3.36, you'll get 9.9 total. If you go to more than this, first gear will be nearly useless because you won't be able to hook up.

Since energy absorption is a function of the inertia times the rotational velocity squared, a 30 lb flywheel has roughly 30 times the rotational inertia of a 3" diameter half shaft; further the ratio of rotational speeds is 4.11:1 in high gear, so the energy absorption of the flywheel would be...

If your driveshaft is turning 9000 rpm, it does calc to ~153 mph with 26" diameter tires and a 4.56 rear end, BUT, if you saw only about 90 mph, your tach is likely incorrect. I'm more inclined to believe your speedo than the tach. As far as drive shaft critical rpm, the stock steel 2"...

I measured the distance from the rear crank journal (as it exits the block) to the edge of the dowel pins, but since it was greater than my dial caliper, it had to be done with an engineering rule. Could not determine any significant difference so I'm guessing that the run-out was the trans...

Automatic Transmissions Can Benefit Also... I had a challenging problem last year with an automatic trans - when the trans was bolted to the engine, the torque converter was in a bind - not good! :smash: After exhausting the normal solutions like ensuring that the pump halves were aligned, the...
