    37s and 3:73s

    31" tire.... 5.13 gears. Out of curiosity what is your hiway speed? Sent from my SM-G975U using Tapatalk

    37s and 3:73s

    Good luck with that. Gearing helps restore mechanical advantage. Larger tires and/wheels though add weight. Tire wheel weight effect you differently then the same additional weight in say the bed. With the right gearing and enough torque down low you might be able to achieve the numbers. Sent...

    37s and 3:73s

    Everybody has a different perception. Running a 33 stock gearing and towing isnt a great idea on a 4l60 variant tranny. It becomes a how long will it last. Go to 35 or 37s and the time is faster. I too doubt 22mpg. I find a 88-98 pickup in perfect running condition to be barely adequate. Uch...

    Small Displacement Diesel Swap Options?

    Its common on higher milages ones. Ive had a few service truck/vans. Coolant disappears and folks blame head gaskets. The 350 makes alot more hp then the 6.2 diesel easily. But the 6.2 can get good mpg and has enough torque to be slow but decent with a small load. Back in that day a gas motor...

    He is refering to the l31 vortec and its issues. They like ls motors have intake problems Sent from my SM-G975U using Tapatalk

    Small Displacement Diesel Swap Options?

    If i remember 93/94 on they had a fuel driver that was temperamental to heat and it was mounted in the engine bay. That was their biggest problem. Compared to diesels of their day vs 7.3 and the 5.9 the problem was a overly high compression ratio that dosent leave much for adding a turbo. There...

    Small Displacement Diesel Swap Options?

    My 16 f350 is quiet. I can hear the car next to me in traffic. Now my 05 f250 is louder... not old school cummins loud but shut it off in a drive thru loud. But ive had gas motors with custome exhausts that were louder. Sent from my SM-G975U using Tapatalk

    Small Displacement Diesel Swap Options?

    My point exactly... 15-20mpg it possible on gas at a savings of 20-30 cents a gallon and cheaper oil changes on a gas motor. On the flip side if this is just a avenue to justify an want.... ive also told myself and my wife things to justify a project... (kinda why a smoker build has gotten way...

    Small Displacement Diesel Swap Options?

    Sounds good. But i dont see much of anything in a pickup doing that. I also see a lot of folks claming their trucks getting extremely good fuel mpg factory diesels getting over 20mpg.... then the next guy gets 11mpg. Now is 35mpg possible? Probably. On the hiway down hill with a tail wind...

    Small Displacement Diesel Swap Options?

    A mechanical diesel would be more ideal unless your a wiring guru or can get a stand alone harness. Just remember your also going to have to make the tranny play along. The diesel thing.... well hopefully you get the mpg. To me the hassle is far more than the gain. Id probably rebuild the 350 or...

    Vortec heads and TBI?

    Comparing a l31 vortec truck to a tbi... the tbi seems to be alot more torquey... Vortec long block vs tbi long block... the vortec motor eats the tbi's lunch. Great off idle power and will pull till redline. Stock vortec heads are only good to 5000-5500rpms if i remember correctly. Way back...

    Vortec heads and TBI?

    In my personal experience the heads make a noticable difference. I swapped them in a truck with a tired motor and it made a difference. Later i went with a l31 long block. The l31 stock motor didnt have timing marks so we set it manually. I ran the heads and the whole motor as well with no real...

    Strength of IFS ?

    Its been years since i thought of doing this. But even the track width, spindles, and such were different. It would be far wasier to get a ford superduty axle set for 300-1000 bucks and do coil or leafs up front. Sent from my SM-G975U using Tapatalk

    Strength of IFS ?

    It uncommon to have a dana 60 in a 3/4ton chevy square body. They usually have a 10 bolt or a dana 44. The only difference between the half ton vs 3/4 ton is the 8 lug outers vs 6lug. ... there is a substantial differemce in axle stregenth dana 44 vs dana 60. Sent from my SM-G975U using Tapatalk

    Strength of IFS ?

    In my 94 swb 4x4. I had 4.10 gears. 35" good year mtrs. Stock height. L31 vortec motor with the sdpc tbi intake on it. Last time i went out playing in that truck probably around 03 or 04. We were wheeling in the candian river around Amarillo tx. I tore the cv axles pretty quickly. This was a...

    Your right if it is extremely hot about direct wiring the fan although in mid temp operations when trying to dehumidify or defrost in low ambiet the fan might hurt performance Sent from my SM-G955U using Tapatalk

    Honestly psi is where you have the problems. The tempratures should follow unless you had a tremendous amount ot subcooling or the lack there of. The truck uses low psi to turn off on the low side to prevent freezing. Sent from my SM-G955U using Tapatalk

    Few A/C questions.

    So.e one else might chime in but id think you might want the fan on a tad sooner then 150 degrees. These are what we typically use in various applications. They are simple open close contacts that use the refrigerant psi rise to trigger the fan. The bullet types are avalible in a wide rage of...

    That should work. On a refrigeration unit we typically set the fans to come on at 100-120 ambient temps. So for r12 probably aroind 150ish. The fan likely will only run while driving slow or at a traffic light. You might have to play with the temp setting also based of the size of the fan. If...

    Few A/C questions.

    I would have it either on a thermostat or psi switch for fan activation. On much larger refrigeration and hvac they use either a headmaster or fan cycling to keep the pressures in line for optimal performance. On the hiway and in low ambient temps the fan likely isnt needed. Sent from my...
