@tommartyn i think that there is a conversion kit that you can get for the older stuff but its hard to find. I could be wrong though dont hold me to that.
-
Ha, thats good to know. Yeah, makes sense to me. the heads are definitely what needs to be cooled first. Seems like a much better design. i wonder if you could make a reverse fin'd pump for the older engines, and it would pump the coolant backwards, cooling the heads first. :) might make something not work right with the thermostat.
-
@tommartyn I think that the coolant enters the bottom of the block and leaves at the top of the block making the coolant hiting the heads at a already high temp so it doesnt actually cool the engine but heat it up. In the newer chevy gas engines the coolant flows in the reverse direction of that and that same system is used in the 6.2l diesel where the cool coolant from the rad hits the heads first then the rest of the block..thats what i learned from my teach at school
-
Yeah, bad engineering. Its weird, because the old mopar stuff stays real nice and cool, and the radiator and all look way less advanced.
-
@tommartyn I think the reason that the older gm gas engines run much hotter is the single row rads and the direction there water pump is pumping the coolant and the size of passages the coolant has to flow through
-
Gotcha. Yeah, that things gonna be a beast man. The 6.5's, espeically being turbo can put out some heat for sure, but these old 6.2's, have awesome radiators, and don't put out alot of power, so they run pretty cool. I've never really understood why, but GM gas v8's get crazy hot. Something is designed shitty i guess, because the radiators are always pretty decent looking. Mopar stuff always stays pretty damn cool. Going from field beating experience here.

@tommartyn ha i was just kinda talking in general wasnt really talking to anyone exactly. I know that they can overheat very fast just as easy as a 350 i think faster then a gasser engine. I am currently upgrading to a 97 6.5l turbo diesel and a nv4500 with my 205 transfar case. I need to upgrade it to either a twin elec fan setup or get a better fan because when i start playing in the mud it gets hot fast

Im guessing you were replying to me. I was talking about a gas 350, vs a 6.2L. I like the 6.2 alot more. And i completely dissagree. I truely belive 6.2's run cooler, and make less heat. On a stock 6.2L truck, you can touch the exhaust pipe while its running and it won't burn your hand, and i've never seen one overheat while beating it 350's will overheat like bitches when you beat them. Maybe more torque then some 350's. I meant to say the 6.2's weight alot more.

@xXLEVERACTION78Xx Are you talking about a gaser 350 or the 350 diesel. The diesel engine makes more torque by far over the 350 but does not have the hp of the 350 gaser. The fuel econ is much greater out of the 6.2s and as far as the heat part diesels runhotter because theyrun off the heat of compression and weight agood amount more then a 350 gaser because the engine has to be beefier to handle the added stressof the 20:1.1 compression ratio and heat that the engine makes
-
@tommartyn no the 6.2 is going to have more torque then the 350
@FPUGUY
I don't know, you left a tough guy comment on a video, how you feeling?

@xXLEVERACTION78Xx
6.2L's are really good on fuel, ESPECIALLY compared to 350's. For most people the less power is a fair trade for the higher MPG.
They sound much cooler then 350's (in my opinion at least.)
And diesel's are just cooler in general.
350's are all over the place, they're in everything. Its boring.
