72 Ford F500 w/ 330 engine - need to replace engine


Recommended Posts

Will 360 or 390 (or other) from 70 something pickup bolt up to existing transmission? Will flywheel from 330 fit on 360 or 390. (Is bolt pattern same?) Will pilot bushing from 330 fit 360 or 390 crank? Any balance problem using original 330 flywheel on replacement 360 - 390? (Apparantly 330 truck engine was interchangeable with 361 or 391 truck engines which, I believe, are different from 360 - 390 pickup truck engines...)

THANK YOU FOR HELP! I believe 330 engine is original to truck but rebuilt...It is MD I think because engine rebuilder had me measeure front of crank & oil pump drive rod... Front of crank is 1 & 3/8 and rod is 1/4....Know I can buy rebuilt engine but will cost at least $2000 w/ 13" clutch and will put more in this boom/bucket truck than it would be worth.... Really would like to put in '74 or so 360 out of pick up which I can get for $300....VIN F50CRP23503 WB 156 Body 48 Trans A Axle F3 GVW 16000 Net HP 164 RPM 3800 DSO 75

OK...If it is a MD...The light truck series will work...it just won't have as much grunt. I am not sure about the pilot bushing size at this point. If different, a replacement should be readily available from NAPA.

Does the 330 have a large distributor with a governor attached? If so, the origional distributor will not work as the 360/390 intake manifold distributor hole is smaller and the 74/ 360/390 may have DURASPARK on it. It is not that much trouble to change over. You may have to use the 330 flywheel because of the clutch size. There should be no imbalance as the FE (except 410/428) and FT are externally balanced. You will have to size up the front crank snout to retain the 330 front drive or possibly go to the 360 front drive. I am thinking the 330 damper will go onto the 360 crank snout.

Anything else, just ask and I will see if I can answer it for you or find an answer.

There should be very few differences, only those as previously described. If it is a 390 (or 360) circa 1973, it may very well be that the block itself is a 391 service replacement block (which is good). It will have reinforcing ribs on the side skirts. They usually came through with no (or few) casting I.D. Nos.

Now remember, this 390 will not have the same low torque as the 330MD and it will have to be reved higher to get the HP and torque, so be prepared. I would not put the governor(s) back on (but do save them).

Thank you yet again! Have 360 (took it out of pick up 3 days ago after hearing it run & checking oil pressure -(40#)) & it sure looks like it will fit. Metal plate between block & trans match original 330 & heavier flywheel from 330 matches! Just like you said! Engine mounts on 360 were from sides & 330 was from front. Will 330 mount bolt to 360 or do I have to fabricate something?
