diesel to gas

[greme]

i know everyone is going gas to diesel, but i'm actually thinking about getting rid of my 6.5 td in my 95 3500, for a 454 gasser. i can't find any info on a diesel to gas swap. anyone done it or know where i can find info?

Hi
Going from diesel to gas is fairly simple.Why are you considering the switch?
GM motor mounts are all the same when it comes to motors that were installed into gm trucks.If you use a tbi motor you will need the computer to go with it.carberated would be way easyer.
Are you having problems with the diesel?93 is probley one of the most wanted year of the 6.5,no computer controls for the motor.Lots of info in other forums if you are having problems with the diesel
Good Luck

thanks for the info. is the radiator the same? well i have heard alot of bad things about these 6.5's. i just picked up a 95 with a really clean body / frame. i plow with it and it runs really hot. i may need a new radaitor. i'll check out the other forums for help witht his motor. i was always a gasser guy. much easier to work on for me.

New radiator and the cooling upgrade are a heck of a lot easier than a motor swap! :D

yeah, i put a 180 temp t-stat in it. ( it has a new water pump already) it helped but the truck still gets pretty hot under a load and with the plow on. next step is the rad. i think the upper part is clogged.

Plowing trucks with 6.5's are known to run a bit hot. Make sure your plow isn't blocking your grille and the vents in the bumper. Next step is to run an OEM T-STAT ONLY! The aftermarket ones are known for all kinds of problems in the 6.5's as the bypass spring is the wrong tension in them. The 99+ water pump along with a good HD fan clutch and a DMAX fan blade should eliminate your overheating. If it doesn't then you've got some issues with the 6.5 that require attention.

Even towing my Bobcat with my '93 I've never had overheating issues. Although, I cannot say that I've towed with the plow mounted as well. But it would seem that the combination of towing the Bobcat with the plow mounted would mean winter weather and low ambient temperatures vs. just towing the Bobcat which more often means summer weather and higher ambient temperatures.

The cooling upgrade mentioned is like this one (http://kennedydiesel.com/categoryresults3.cfm?Category=1&SubCategory=65&SubCategory2=9) from Kennedy (others assemble similar kits). Basically, it converts the single thermostat setup of the earlier models over to the dual thermostat / high flow water pump setup of the later models.

It has been proven now that the 99+ with the spin-on fan clutch is a far better water pump. The 97-99 HO pump has a balance flow problem where only roughly 20% of the coolant will go to the passenger side where overheating is the biggest concern. The 99.5+ with the pin on fan clutch has proven to flow roughly 40-45% of the coolant down that side and has eliminated alot of overheating problems for many people now. The single T-stat housing is also reccomended now over the dual housing. The dual housing doesn't have the plunger on the T-stat to block the bypass when the stats open and this can cause reduced radiator flow. I know that there is a shop out there who has been published that has done extensive testing on this and has proven that the 99.5+ spin-on water pump with a single t-stat housing along with an OEM stat has dramatically helped in evening out the heating and virtually eliminating overheating in many a 6.5 that used to run hot.
