Thanks, Paul!!!!

Wow; I wonder where I could get a pair of those "heavy-dury" rear drums and shoes for my '64 Valiant slant 6 turbo car? I need all the help I can get, holding it on the starting line, power-braking tobuild boost for the launch (don't want to have to put a trans-brake in it, if I can help it...)

I'm thinking these wide, 11" brakes would do wonders.... but where in the world would I find a set????

Dodge trucks use them in the 70's-80's.

Thanks, Chris; we are planning on trying to use full boost from a power-brake "launch," which is a good prescription for "rolling the lights," so exemplary rear brakes will be mandatory. We'll probably end up with a transbrake, but that's gonna be a last resort... don't wanna have to do that unless there's just no other way.

Thanks again; that truck application opens up a whole different area of possibilities, and one I probably would never have thought of!

You da man....

Lamb use to make a pinion brake that bolt on the front of the rear end air operated, this deal would hold.

Cheech,

Performance results of the 1968 383 Road Runner were all over
the board,,,,,,,,depends on what magazine article and review analysis
you read.

Originally, Plymouth advertised the Road Runner as 'a $3000 car,
and 100 MPH'.

Also, advertised it as 'a low 14.00 second car and 100 MPH, for less than $3000'.

Here are some of the 'Magazine' results I found;

15.31 @ 91 MPH (Car Life),,,,,,,,,,,,,,,,,,,,,,Automatic with 3.23 gears

15.10 @ 94 MPH (Popular Mechanics),,,4-speed with 3.23 gears

15.01 @ 94 MPH (Cars Magazine),,,,,,,,,,4-speed with 3.23 gears

15.00 @ 96 MPH (Car Craft),,,,,,,,,,,,,,,,,,,,,4-speed with 3.23 gears

14.74 @ 98 MPH (Hot Rod),,,,,,,,,,,,,,,,,,,,,,,4-speed with 3.55 gears

15.03 @ 94 MPH (Car & Driver),,,,,,,,,,,,,,,,Automatic with 3.23 gears

14.89 @ 94 MPH (Hi Performance),,,,,,,,,,,4-speed with 3.23 gears

14.86 @ 94 MPH (Super Stock),,,,,,,,,,,,,,,,,Automatic with 3.55 gears

14.99 @ 95 MPH (Popular Hot Rodding),,,4-Speed with 3.23 gears

15.09 @ 93 MPH (Detroit Auto News),,,,,,,Automatic with 3.23 gears

15.01 @ 93 MPH (Motor Trend),,,,,,,,,,,,,,,,,,Automatic with 3.55 gears

14.90 @ 93 MPH (Road Test),,,,,,,,,,,,,,,,,,,,,4-Speed with 3.55 gears

All tests were performed between October 1967 and December 1967.

Most (not all) magazine writers couldnt drive a nail with a hammer. Put a decent driver behind the wheel and they could shave about 1/2 of a second off of those times.
