Be cautious, the 480 volt system may be a 3 wire, 4 wire or high resistance grounded system. Only the 4 wire solid grounded system will support 277 volt lights without side effects. The 3 wire or high resistance grounded system requires a 3 to 4 wire transformer to operate correctly...
Last night's test run was quite informative.
Ambient was about 65F
City driving resulted in a stabilized engine temperature of about 190. (180 Thermostat). Typical upper radiator temperature was about 10 degrees cooler, typically 180. Lower radiator temperature was about 10 to 15 degrees...
When designing a transmission adaptor plate for an Automatic Transmission 4r70w or A40DE or e40d to another engine, assuming that the machined surfaces are parallel withing the oem's factory tolerance, how much misalignemnt shaft center to shaft center is practial, tolerable, and typical?
Are...
Maybe.
If you have access to both transmissions check the identity code on the transmission. Something like PRA-CBA, if the two codes match then you have a winner. If the codes are different then it gets a little tougher. Try googling the codes if they are different, the transmission...
Hmmm,
Got temperature probes on line.
Locations:
Radiator Inlet (Tank near upper hose)
Radiator Outlet (Tank near lower hose)
Coolant in Intake Manifold, (Water Passage Behind Distributor)
Oil (Lower Left Side of Pan)
Trans cooler in / out.
Trans cooler is connected in series with trans...
I Don't believe there are any head gasket problems, engine runs good, coolant level is stable once full, oil is clean, no steam in the exhaust.
Will check timing.
A/F is a 800 cfm edelbrock carburator, A/F ratio is at best "dynamic" :-)
I have recently learned of Robertshaw Balanced...
The mystery deepens.
I put in the brand new 3 core crossflow radiator, and a fresh 180° thermostat for good measure.
Went for a drive on a 75° evening.
The cooling system behaves quite differently but still not right.
Before the car would always cool back to normal if you could get on...
First 400M spun a rod bearing a wrecked the crank, second 400M got parted out when the car was retired. The 400M made good power, the 76 LTD would chirp the tires going into second gear and topped out at 145 mph.
Some preliminary info on the temperature readings from the last couple of...
I am intrigued with mikes experience with clogged passages. I had a 76 LTD with a hopped up 400M and as the years wore on a noticed that it would heat up under heavy load on the highway. Ironically the problem was seperation of the water passage from the cooling little metal wrinkles of heat...
Seriously, back to the very fist post, I want to try a smaller water pump pulley to increase the fan speed relative to the crank. The present pully is 6 1/2 inches and I know there are smaller stock ones around. The older mustangs have about a 5 inch unit. The present fan is a 6 blade solid...
I want to connect a aodE-w or a e40d. The e40d is larger and will likely take more HP with less modification. I have in my possession a 95 e40d from a 3/4 ton truck. (351W)small bolt pattern.
There is a e40d for the 460 but they seem to be quite rare. Hence $$$
The opposite is true of...
Reply to stout:
Sure, the transfer punch is great for boltholes, how did you ensure crank and torque converter alignment?? I have seen the odd shop gut a block and transmission to put a solid shaft in to line thing up, but I am not THAT ambitious
Fan shroud - yes
Temperature gauge tell you that you have a problem, a flow meter may tell you why.
Guess it's just the P.Eng. in me. :-)
I agree, fan speed / air flow is also important, hence the smaller pulley that started this whole thread. :-)
Im am considering the clutch fan, since...
I would be interested in obtaining the 302/351W block bolt pattern. Is it on CAD or a dimensioned drawing?
I have seen one aftermarket converter plate, it is very expensive and tilts the transmission relative to the engine. I think I can do better.
With the water and laser cutting...
Interestingly enough, the stock pump with the cast impeller did seem to perform more reliably at low rpm. I have some suspicions that the edelbrock pump is made for those in mind that idle their overcammed engines at 1500 rpm.
To enhance the story some more, the motor is in my 1971 ford LTD...
In general terms I would agree with the pulley suggestion, however there is more to the story. Engine displacement has increased to 514 CID, there is a automatic transmission cooler tempering the air before the radiator, and the waterpump is a cast aluminum edelbrock unit that seems to be...
Anyone have a legitimate bellhousing CAD drawing or techinical information on dowel pin locations and boltholes for these two engine/transmission bolt patterns.
I have hand measured both and reasonably accurately documented them, but an "official" measurement / pattern would be greatly...
