    My 454 SS build

    I went with Flex-A-Lite Monster Universal-Fit Electric Fans 294, Flex-A-Lite Electric Fan Mounting Brackets 28000 and put a 454 radiator in it. I did use the option to use the on/off/auto switching. You can get this from summit racing.

    My 454 SS build

    Plus the Gearvendors will work behind the 4L80E. I have one behind my NV4500 MW3 and 14 bolt 9.5 3.73. I get 19 mpg on the freeway @75mph with a stock tbi 350. Overall this is a cool build. But, I cried a little seeing the covenant 454SS body and interior Modded. I can see swapping to 4l80e...

    88GMCtruck's 98 Silverado Towpig Build: "Black Fox"

    But I just had it rebuilt but with Cryo parts. so I wound up paying $1500 to bullet proof it. It is now rated from 475 to now 613 ft-lb of torque.

    NV3500 breaking point?

    When I swapped my NV3500 for the NV4500, I added a gearvendors to it. I learned to float the gears with the GV.

    NV3500 breaking point?

    With my experience with these transmissions, I have had two die on me with a bone stock engine. The first one while heading on leave to my parents. I was on I10 south of El Paso, TX. Cruse on 75mph, all of a sudden RPMs went up. I had 4th but that was it. I flipped back at the boarder patrol...

    NV3500 breaking point?

    Joe gibbs may have had the tranny upgraded, which I know a company who does provide cryo treated parts that gives it 30% more strength.

    88GMCtruck's 98 Silverado Towpig Build: "Black Fox"

    Is this a Dodge NV4500 or GM NV4500? They are slightly different. The dodge one is a little more beefier than the GM in the input shaft do to it being slightly larger. The splines are different in the output of the main shaft. Dodge NV4500 has issues with 5th sliding off the counter shaft while...

    92-94 Gauge Cluster Swap

    I was thinking it came from a stripped down model.

    92-94 Gauge Cluster Swap

    Honestly, never seen one like that. I did a bit of research and found one Kodiak that had one similar. Its a GM for sure. I will expand to other brands of GMs. There are some overseas cars and trucks we don't see here, like Holden in Australia. But that don't mean it was a one year cluster. I...

    NV3500 breaking point?

    The most important thing to remember, its not how much HP you have, its how much torque you putting into the transmission you are using. Reminder, NV3500 has 300ft-lbs input torque. I like to go 10% less then the tranny back. I also like to make my build from the rear wheels forward and tune the...

    NV3500 breaking point?

    They are one in the same. the only difference will be the final gear ratio. For example, If on guy has a 5.3L and another has a 4.8L. Both have the same 4L60E but the 5.3L has 3.23:1 final and the 4.8 has 3.42:1 final. Using these two because they both in my front yard.

    Before and after thus far, what you guys think

    I feel that he will be fine but need to recalibrate his DRAC or VSSB module which controls your speedo. with 3.73:1 with 33's your DRAC/VSSB would be 1011111 DRAC and 0100000/1011111 for VSSB. 35's are 1100011 DRAC and 0011100/1100011 on you VSSB. depending on year model you will either have a...

    You most likely have 3.73:1. Your RPO codes in your glove box will tell you. If you need a list of the gear ratio codes I can post them.

    NV3500 breaking point?

    NV3500 MG5 has a input torque of 300ft-lbs. with my stock 350 pulling 212hp @4000 and 300ft-lbs @2800 I have had two fail and one of those went out leaving me with only 4th gear. I swapped it with a NV4500 MW3 2004 model. NV4500 can handle 475ft-lbs. Now, I'm in the process of building up my...

    Dick Cepek factory installed lift?

    I'm looking at possibly purchasing a 1995 K2500LD that the owner was told that GM did 150 of these Dick Cepek lifts. I haven't found anything on the factory doing this mod for there production trucks. This is the first time I'm hearing this. The only factory off road package they did was the Z71...

I have been trying to find a blue 60/40 bench but also wrestling the thought of losing my arm rest so I think I am going to find a 2010 seats and have the...
