Hi, i have some questions for the very experienced people here, please help...
i apologize if this subject has been talked here, i searched and did not find any 100% clear info just some vague info.
Ok well, for Introduction, i can say that my dad has an 1980 F600 dump truck Std with dual, and with a 370-4v engine wich is losing power everyday, so he wanted to rebuild the engine but is very expensive (about $2,500dlls), and with this economic situation is impossible for the moment, he asked too for the prices of a used engine, but when he said that the engine is for an industrial truck the prices were very high too (about $2000 dlls).
Researching in the internet and overall in this usefull forum i have seen that the 370-4v shares a lot of components with his "bigger brothers" from the 385 family the 429 and the 460 engines, and looking for this engines in the used engines yards now i know that they are a lot cheaper than the 370, i saw some used 460's in $300 dlls near the san diego area, so my questions are:
-Can i swap a 460 or 429 in the truck instead of the 370 without any extra parts like mounts, etc ? Does the bellhousing/mounts fits like a bolt on (plug and play)?
-If thats a yes, wich engine you recommend most, the 429 or the 460 ?
-Is there a difference between a 460/429 from a pickup or car, apart from the oil pan ?
-Anybody here has done this swap ? how was it ?
-Do you have an extra advice ?
-Does the distributor from a 429 or a 460 fits the 370 ?
Thanks in advance for all the info and advices, me and my dad will appreciate the Help.
I can help some, but theres a lot I dont know as well so some of this might not be 110% correct.
First thing you need to study & learn are the block casting numbers. Numbers are located on the left side of the block right beside the starter motor & down under the intake in the lifter valley.
Numbers & letter in the lifter valley, left to right indicate the year, month, day the block was cast.
Block numbers starting with C = 60's year models, D = 70's, E = 80's, F = 90's. 385 series were made from 1968 to 1999
60 & 70 year model casting numbers were located on the outside edge above the spark plug between # 1 & 2 cylinders left side & 7 & 8 on the right side.
80 & 90 models, those numbers are on the inside, underside of the head between intake ports 1 & 2 left side & 7 & 8 on the right side & the intake must be pulled to check them & even the heads pulled. Sometimes you can take a small mirror & with the intake off hold it in a way, down in the lifter valley & see the numbers. May need a little light as well.
Few days ago I was checking engine blocks & heads at a junk yard & took a piece of thin white paper, held in place over the head number & rubbed it & was enough greese there to put an impression of the number good enough to read. Kinda cave man but it worked.
Most of the car engines you find will be D1VE castings. Pickups, vans & trucks, D9TE.
Look for the TE at the casting number end indicating a truck engine.
A DOOV-C block was one of the thickest block castings & could find some with 4 bolt mains, but the 2 bolt should work just as well for what your intending to use it for.
Probably what you will need to think the most on, would be the heads, getting then up to par to do the task ask of them.
That dump truck will put a lot of load on the heads & in turn whole lot of heat, so things like Stellite or Carbide valve seats, Sodium filled or Inconal exhaust valves & quality guides pressed in will be needed for them to do the job.
I know some more, but out of times right now, so I'll let somebody else have the soap box for their input.
Thanks a lot for the help sir, i can see that you have a lot of experience.
Anyone else wants to share knoledge ?
Oh no, not me, I'm still a greenhorn newbie here & to the 460 engines but my hands have been greasey for 44 years.
Might take a little while for somebody to respond that realy knows about the swap your doing, if anyone has done such. The 370/429 & 460 blocks being about 95% same as each other, shouldnt be a problem on the engine fitting where the 370 was. Its just from the flywheel back that might bring on fitment problems.
Once you have the 370 & trans out of the truck & the 460 sitting, you could test fit everything & see if it will all match up.
Back of the blocks should be the same, but dont know about the end of the crankshaft if its the same bolt pattern, same OD or same ID where the pilot bearing would fit. End of the cranks probably going to make it a go or no go.
yes the crank ends are bigger on the 370. theyre fe size (1.85") vs regular 385 series (1.375") also the 370 has a small bore (4.050") vs the larger 429/460 bore (4.360") but otherwise the block is basically the same. the heads/intake/oil pump/oil pan/distributor all interchange and should be swapped from the 370 to the 460. id recommend getting a 460 over a 429 because it puts out more torque being 31ci bigger. the only issue youll have is youll need the flywheel for the year of 460 you get... if the 460 is from before 1979 (c8ve, c9ve, d0ve, d1ve block) youll need a neutral balance flywheel, if its a d9te block then youll need one for a 1979-1997 460.
Jose I've done this swap several times with no problems E Mail me for the details
Hey hotwrench I am new to this site any way I also have some questions about 370 460 maybe you would be willing to help me with. I'm looking to mate the f700 5 spd to a 460 if that's possible any input would be much appreciated
