Re: Attn: SNORTclown
Hey SNORTclown,
I never said that I haven't broken Toy diffy's, nor have I claimed such a setup to be the be-all end-all of durability. I actually PREFER D44 diffy's, even though the AXLE strength doesn't appear to be any better. But stock diffy to stock diffy, I'd pick a 44. I won't put one in my truck because the cost (both in $$ and in lost ground clearance) wouldn't justify it in my mind. But, if you recall, this thread didn't begin with a Toy vs. 44 debate. It was a Toy vs. 30 debate. I WOULD up for a 44 front if I had a 30 there now.
The Toy diffy's I have broken have been stock, 18-year-old 4-cyl 4.37's (worst ratio Toy made) that were on the truck when I got it. Imagine my dismay to find that after I got the truck home, the gears had NO LUBE. They lived for 18 months after I filled 'em up & during that time survived more abuse than my Dana 30's ever did. And I CAN upgrade to better Toy parts without an expensive swap to Dana components.
I never subjected my 30's to larger than 33" tires or more power than a 304 that was so worn that it wouldn't hold a hill in 1st gear, low range - compression was that weak. Yet, I went through 30 fronts at an astonishing pace. Oh yeah, these were open 3.73's (41/11), so no low-teeth counts to deal with. No real way to improve on that front without getting rid of it. When I moved up into more serious racing, I ditched that 30 front. My #1 competitor almost lost the state championship to me because he broke FIVE long-side 30 axles in ONE season. Fortunately for him, that typically took place near the end of his run. Currently, we have 2 heavy hitters still running 30's. One with a hot 360 & one with an even hotter 390. Both have broken enough parts just in the past 2 seasons to justify something better.
My Toy diffy's on the other hand have been subjected to 38's and a 408 that I can assure you does NOT need a rebuild. The lowest my truck placed in any 1999 event was 6th. Most of the time, I was running against 40 trucks or more. Here's the breakdown for ya.
06/12/99 Marthasville, MO Street Stock up to 36" - 1st place
07/10/99 Niangua, MO Street Stock up to 37" - 1st place
07/10/99 Niangua, MO Super Stock up to 40" - 1st place
08/14/99 St. Charles, MO Women's Hot Street up to 38.0" - 1st place
08/14/99 St. Charles, MO Hot Street up to 38.0" - 3rd place
08/21/99 Sullivan, MO Street Stock up to 36" - 6th place
08/28/99 St. Charles, MO Women's Hot Street up to 38.0" - 6th place
08/28/99 St. Charles, MO Hot Street up to 38.0" - 2nd place
09/11/99 Washington, MO Street Stock up to 36" - 2nd place
09/18/99 Marthasville, MO Women's Pro Stock - 5th place
09/18/99 Marthasville, MO Street Stock less than 36" - 1st place
The engine is a fresh 1970 4-bolt 400 bored .040 over. Balanced with 10.2:1 compression - forged BTW. .234/.244 dur, .488/.510 lift, Performer RPM intake & MSD 6AL. I go for 2nd with my B&M slapper immediately after nailing the throttle & had to bump my rev-limiter up over 6 grand 'cause I was getting into it before I could complete the shift. This is with a STOCK converter, BTW.
And since you clearly don't know JACK about mud racing, here's a tip. NITROUS IS ILLEGAL IN MOST CLASSES. D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH! D'OHH!
You know, I too was ready to let this thread die. Then someone has to get on here & tell me I'm not breaking stuff because my motor sucks??? Wow, that was REALLY helpful, don't ya think? You are exactly the type of person that I want dishing out advice. Please DO tell me how to build my next truck. I'm ALL ears.
