i'm doing the 351m 460 swap i have a 4sp trans and also changeing to automatic i have another 4wd truck with the auto c6 79 and i have a 78 motorhome with the460 i'm useing i was wondering abuot the torque converter in the motor home will it work in the 4wd trans? i was thinking the rv had a litle bit of a stall and does any one know about what kind of hp i have? d8ve heads 4bl i put a dilindecater on the cam while i had the intake off and rotated the motor it semed to have the readings of almost a 268 cam 28,000 miles on motor

 

if they are both C6 transmission then the TC doesn't care what is bolted onto the back of the trans.

Your heads would be D3VE casting not D8, probably dirty casting or just gunk buildup making the 3 look like an 8

 

casting not dirty it is a d8 meaning its a 78 mod. i found this out from another post. i was just woundering about the splines from the 2wd trans to 4wd trans i had herd thay weren't the same on output shaft

 

There is no such thing as D8VE casting number on 460 heads.

 

google d8ve heads. you will see others have these heads. not tring to make you mad

 

Actually the converter seems to be lower stall than normal. I recently pulled a trans and converter from a similar rv and put in my 2wd truck. It is great for cruising(really tight) but not so great on performance , even though my motor is built up . My power band starts at 2600 and it cannot get there until I build road speed, so the converter stalls 1800-2000 max estimated.

 

And you will find that not one of those actually exist. D8VE is NOT a valid casting number for any 385 series head EVER. This isn't google this if FACT my friend. Ford used D3VE heads from 1973 until the mid 80s They NEVER changed the REVISION number (it is NOT a part number it is a casting revision number ONLY) Any and ALL that appear to be D8 are actually a dirty casting and are actually a 3. I don't have to google it, I don't have to see yours, the fact is Ford NEVER made a D8VE casting revision for 385 seres heads.

you want further proof? You seem to think that means they are 78 heads (may or may not be) but go look for the date casting number and see if it really was even made in 78, or look above your starter what is the casting number. I will put money it's either D9TE-AB or it's D1VE so I guess ford only made 460s in 71 and 79 (The D9TE blocks were used until the end of production in the 90s)

This is exactly why I make it a point to try and correct when people are posting wrong information. It comes up on google and suddenly it's gospel. Do you know that a hot rod magizine once published that you need to find a truck block with the D7 or D8 casting number cause ford used 4 bolt mains on the truck blocks. Just cause some mag wrote it, doesn't mean they exist (I still have an outstanding bet that NO ONE has ever been able to claim on this one)

 

so you are just saying i have a bad casting from the plant. i'm ok with that i'm not calling you alair. i thank you with the info and others with this casting probly understand better too

 

Interesting, both Google and Wikipedia do spread inaccurate info on many subjects...
so what would be the code on year 71 & 72 heads? are they still marked DOVE, or are they D1VE, and D2VE ?? and are they the last years before the 5/8 spark plugs

 

Rob is many things, but he knows his stuff on the BBF! There is no such animal as a D8VE head. If it's from a 78-79 motor, then you've got the D3VE-A2A heads. Like rob said, get some degreaser and a scraper and after you clean them up, you'll see what they are.

 

this motor has 28,000 miles on it it's not even dirty. but i washed it and buffed the numbers. it is there. i know you guys think i'm crazy. but i'm not some 1 time builder i do this every day for 20 years. case dealership i deal with casting numbers every day.i can take a casting number off a head, of a case, punch it into dealer computer and it may come up as invalad number. most people load the most used of these years into the computer. others are lost. this maybe the case or not. but i'm a good guy and like this site i've learned many thing here. but i'm not a liar monster baby. i try to help others. and be open minded

 

I hadn't seen this post yet
For 71 the heads were D0VE, there was never a D1VE head (they did use D1VE for blocks though) And like I told you earlier they are REVISION numbers and since ford revised the heads in 72, they revised the casting number and it was D2VE. This is considered the worst of the 429/460 heads due to being open chamber and very prone to detonation. Due to that problem they revised the heads again in 73 and made the revision D3VE which was used up until the 80s.

You never did say what your block casting number was. This should be a clue to you on this. I don't even have to guess that the number on the block won't correspond to the casting number on the heads (they didn't after 72 at all) if your engine is a 73-78 it will have a D1VE casting for the block... Do you think that means that ford never made any blocks after 71? Or if yours is a 79 or later (clear to the end of production) ti will be cast D9TE-AB, guess that means ford didn't make any 460s after 79.

This isn't being mean, it isn't calling anyone a liar just giving true facts.

 

yes it's a bad casting number from the factory. They ARE D3VE it may look like an 8 but trust me it is a 3. And as Bill (numberdummy) will tell you casting numbers do NOT correspond to part numbers and can't be crossed or punched into a computer. They are engineering revision numbers (ford DID use them more as year casting numbers in the 60s but pretty much stopped that practice after 1970 and it wasn't 100% even before that)


Also you will find a number cast on a slightly raised part inside by the valves usually THAT is the date casting number telling you when it was actually cast. it will be something like 7 F 25 (that would be Jun 25th of 77)

 

How about some pics of the heads, showing the casting number? I'm curious now. I'm still with Rob and think you have D3VE heads, just a bad cast.

 

i beleave you guys 100% this is just bad casting. i had a old ford parts guy look at this he said yes it looks like a 8 but it probly supose to be a 3 ford had some bad casting back in the day. well back to tring to get this old truck going i just ordered the motor mounts. looking forword to warmer days this gettin parts off old trucks in the cold sucks
