Mopar 8 3/4 question

GeneWilsey · 11-29-2013, 11:54 PM

The transmission is a lightened, rollerized 904 but not a protrans. The converter is a custom Ultimate converter designed by Lenny. After a couple of updates it is spot on. The converter is on the tight side because the G70-14's do not hook like slicks.

Jeff, we are trying to take 150 pounds out of the car for next year. We were wondering if reducing the rotating weight would gain us more than just the weight gain itself.

I understand the housing doesn't fit well. We can't run one so I only know what I have been told. I don't know if they are in the book still, but there are some around. Could you just have your 35's drilled & lightened & save a little. Also are you running a stock housing? They bend unless well supported or braced? If the axles go in easy, it's straight. I always found the right side would bend forward. Lightweight trans worth at least a tenth over the roller trans. Pricey though. What ratio in the trans? Might be something there. With the lightweight stuff and straight cut geats ratios range from 2.00 to about 2.80 first. Be easy to calm that thing down for those little tires. How about front shocks? I got some used Strange Double Adjustable from our SS car. Good shape, replaced all of them with Santuffs. Or what do they allow? Cal Trac shocks best buy for the buck. 90/10 and adjustable rears. Can you run roller tappets? Comp makes a roller conversion with special tie bars that go right in a Mopar. Just got some for our old Top Stock motor. I got some more things. email me jefft@southlanddodge.com or 985-804-6161

This in itself will pick the car up.

What I would suggest is taking advantage of this and move weight to areas that will allow you to full throttle the car off the line.
Are you allowed to use a ignition system that would allow you to alter the ignition curve in an attempt to calm the power slightly on the hole-shot in a effort to get the car to leave quicker?

I have the lightest stuff made in my car, and some of those items may be massaged a bit

I believe that 1 of those items alone may not be worth much or "anything", but what's ten of them worth. You have to be tenascious and cut, grind, shorten, drill or lighten anything that turns. Email me if you want at wadeowens2007@yahoo.com

BES built an engine for a red 71ish Mustang that ran into the 9's in a similar class. Those cars are unbelievable!
