64 c10 help?

[FAT TONY]

alright well ive been riding around with the ticking in my engine for a while but been noticing that its been heating up quite a bit when running it is 210, and when turned off it goes up to 230 any body know what is the correct operating temp of the l6 230? and rite now it is running on water is it possible that that may also be a problem should i add some antifreeze maybe it wont heat up as much, also what kind of transmission did these trucks come out with ?. like is there a model or serial number some were that i can get more information of the transmission?, and one more thing any one know what is the max speed of a 230 l6 with a 3 speed tranny on it ?.... fastest ive gotten it up to is 50 mph im pretty sure it should have more speed than that
any information helpful

[FAT TONY]

anything?

The temp will go up after the engine is shut off. IIRC its called heat soak and it happens because the water pump isn't moving water anymore. It might creep up a little more too. Are you going by the factory gage, or do you have an aftetmarket gage. I've heard the factory gages are not that accurate

210 deg. isn't overheating. Plain water will boil at 212 deg so you should be running antifreeze which raises the boiling point of the coolant, not to mention corrosion protection. You may be losing coolant in the form of steam. If your water reaches the boiling point, your water pump will not pump steam bubbles very well. Your other question " how fast will a 230 six go?" That depends on your rear gear ratio, tire size and whether you are going up hill or down hill.

wekk i put some antifreeze in yesterday and it really helped now it only goes up to 210 when off and running its about 190 or less, and i installed an aftermarket gauge which helps alot

is it best to have 50/50 or more antifreeze than water?
and i thought the cooing system is a sealed system kind of like the fuel system to help loss in gas form? i could be wrong,
well im really asking because ive noticed that when i shift from 2nd gear to 3rd gear the speed doesn't really change much , it stays around the 40mph

Your cooling sytem should be a air tight system if not it will cause you overheating problems, It would be a good measure to make sure your thermostat and radiator cap are in good order also...Ive always was told 50/50 is the mixture you want but i dont think it would hurt if you had a little more coolant..

Hahaha. Yeah, I'm pretty sure the downhill aspect should increase speed noticeably! Water boils at 212 f under regular atmospheric pressure. At higher temp with with coolant and higher yet under pressure. Make sure your rad cap is still good or you may have no pressure and could be losing water.

Long ago, I had a 63 230/3spd truck with what I believe was the standard 3.73 rear end and I remember it being a very peppy little combo. Top speed was above freeway pace but probably not by much (maybe 75-80 mph). I never ran it to where I thought rods were gonna start flying.

[spacedebris]

Its been a long time, but I think I remember the normal operating temp should be 200-210. Sounds like your running at the upper end of normal.

depending on how 'stock' you want to keep your truck, you could install an electric fan with a timer to run for a short time after you turn off the truck to help cool it down. My brother has one installed on his 72 Blazer with a 350. His used to run about 200 while driving but heat up beyond the gauges ability to measure after he turned it off. With the fan now it helps keep it under 225 after turning off.

I would defiantly run antifreeze if it were me. I'm also a fan of water wetter. I personally like to keep my temp between 190-200 when possible and the water wetter does a great job of helping to do that.

thanks, and what temp thermostat is good?, and rite now i think i have about 75/25 mostly antifreeze it worked out better for me

around how long did it take to reach top speed?...... i went on the freeway and was up there for about two miles but got off cause i barely made it to 50 mph felt pretty slow having every one pass me up, ive noticed that some times it sounds like the rpms are to high but there's no more gears to shift to so i let off the gas

well since ive put anti freeze it is pretty good but i also have to get a new fan guard cause im pretty sure that is a factor in the temp as well

My 65 has the 230 3 speed and it will run all day at 65-70 mph. I don't know what gears are in my rear end, but it really is a nice set up. Lots of hills around here too, and that hasn't been a problem either.

well when i purchased the truck the previous owner said that the tranny needed some sort of adjusting so im starting to think that might have something to do with it, also wondering if timing is a factor in the speed as well?..... i mean honestly i have no problem going slow cause im more of the cruising type but sometimes i have the need to go faster

[FAT TONY]

also though about something just rite now "hopefully no body laughs at me" but could it also be that my speedometer is off some how?, i know for a fact that i am going slower that the rest of the people on the highway but not certain if my speedometer is reading correctly

[1963c-10]

I run a 180 thermostat in my 63 w/230 3sp and 3:90 rear. Does 70-80 down the highway, but I wouldn't push it much more than that....stock brakes, suspension, 50 years old. I dont have any issues with overheating, although it does have a 3 core aluminum rad in place. Stock water pump, no shroud and I installed a spacer to put the fan closer to the radiator.

You may have more than one issue causing the truck to be slow. It could be tune-up related, or rear end ratio, or possibly your forum name has something to do with it? Just kidding.

[FAT TONY]

well ive been asking around and some one said it could be my clutch that's burnt out or something, cause when i shift from 2nd to 3rd the speed doesn't really change much

[FAT TONY]

how can i check my rear ratio? well im planning on putting in a 350 pretty soon but if its not the engine then i don't think that would make a difference in speed

Your clutch may not be perfect, but I doubt it's what is causing this trouble. If it won't shift at all, or slips when you accelerate, then maybe. Sounds odd that nothing happens when you shift. Do you mean The RPM does not change? If the RPM does not drop significantly when you shift from 2nd into 3rd, then you're not really shifting to 3rd. Maybe you have trans issues? I don't get it.

[FAT TONY]

well when i purchased the truck the owner said it needed transmission adjusting but didnt specify what it needed.......... and i go from 2nd to third and the rpms drop but in 3rd the rpms start goind up but the truck wont go any faster

[FAT TONY]

how can i find out my rear end ratio?

[FAT TONY]

? any one

[billd5string]

The common way to find the gear ratio is to just jack up the rearend and count how many times you need to turn the drive shaft to make the tire rotate 1 complete time. If 3 and 1/2 driveshaft rotations equal 1 complete tire rotation, that would be approximately a 3.50:1 ratio.

Another way is to track how many RPM the engine is turning at a given speed (in top gear), and calculate it out (with also requires the tire size). There are several speed calculators on the internet which allow you to type in the numbers to figure out the gear ratio.
