What's a High Boy?
Heard the name often enough I thought I'd better ask - yrs, model, options.

Also heard it applied to carbs (Carters', not sure on that either - so if U know that as well - RSB? K? etc, yr, what model on etc...l

Thanks for your assistance.

This is one of the most FAQ's here on FTE, there's prolly 5,000 threads on the subject.

1) The term "High Boy" (not Ford terminology) was originally coined for 1973/77 (1977 before serial number Y20,001) Regular/Crew Cab F250 4WD's, which were available as a Cab & Chassis, Styleside or Flareside pickup.

Today some people refer to all 1959/77 F250 4WD's as High Boys. The last High Boy was assembled before serial number Y20,001, which occured mid-model year 1977.

2) Hi-Boy = Old hot rodders term for 1928/32 Ford Roadsters with the fenders/running boards/splash shields removed exposing the body riding high atop the frame rails.

3) High Boy = Antique furniture term for a New England chest on chest (dresser) made circa 1750/1805.

Calling a carburetor a 'high boy' is a new one on me. I've never heard of any such thing.

 

Cekkent:
U da man! Thanks - Funny how some posters were sayin "dis thread is too old 2 respond to" and "don't post for sale topics" when the latter wuz not an administrator.

OK, everything fits for the neighbor's but it seems he has a high pinion D44. Over 33 yrs some 1 could a put it in but don't C how it misses the oil pan as some 1 said it would...

I should a known this 1 woulda pulled U outta the woodwork.
Good to see you again!
May B I should get to know how to use the "Search"?
OK, that helps n confuses me.
1) Some say 63 - mid 77, others 67 - 77 1/2 and some follow, as U do, the model change 73 - 77 1/2 (actually 79 but we know this un's 'different guts' vs sheet metal). But how could the 59 n up reference be used?

2) Some say (& here I remember your ~ 30 yrs employ & 80 yrs reference ability) last 250 4 wd with the serial # < Y80,001 > & B4, yourself <Y20,001> and B 4.
Coulda some 1 had a finger slip here? Again I defer to Your knowledge n experience.

Thank you both (& 'those who follow' as we say on my forum).

 

Warning: Information Overload, read at your own risk!

1977 F250 4WD's assembled from serial number Y20,001, 1978/79's are not High Boys.

Serial number Y20,001 (which occured mid-model year 1977) comes from the truck parts catalog, because it's necessary to know when parts are looked up that there were two different F250 4WD's offered in 1977.

What the hell is a 77.5 or a 77 1/2? Neither is Ford terminology.

People that use these two terms inre to High Boys are unclear on the concept, because 77.5 or 77 1/2 could be taken to mean non High Boys.

Ford introduced factory installed 4WD in F100/250's in 1959 (F350's in 1979). All the 1959/76 and 1977's (before Y20,001) have a slight lift to them, where the term High Boy comes from.

1959/60 is one body style, 1961/66 is another, but...1966 F100 4WD's have front coil springs, use the same fenders as 1961/66 F100/250 2WD's, the same cab as 1965/66 F100/250 2WD's.

And...if a Styleside, 1966 F100 4WD's use the same bed as 1964/66 F100/250 2WD's. ALL other 1959/66 Styleside 4WD's use the 1957/60 Styleside bed, as do all 1957/66 F350's.

 

so the yXXXXX or xXXXXX are not vin #? I thought it wuz. No wunder mine (of same era '70 & '77) has 4 ltrs & 7 #s & these R only 5.

Well, well, well, seems the high boy is as venerated as the bronk. Or is that just true of all these restored/never let goooed vehicles. I'm over on the sorta-like 300 I6 forum and it's the same (as me w/the bronk) adamant!

 

The Y20001 is last the 6 digits of the VIN# in 1977

 

1961/80 all trucks and Econolines ~ 1966/80 Bronco's: The VIN has 11 digits. The last 6 digits of the VIN is the Numerical Sequence of Assembly = the vehicle's specific serial number.

1978/80 serial number: Ford used two letters, followed by 4 numbers.

1967/77 serial number: Ford used one letter, followed by 5 numbers.

1961/66 serial number: Ford used 6 numbers.

 

the 6 digits of the VIN#
so it looks like the 2 left columns (for each '76 & '77) are block numbers that include the high boy, steponit; and for the high boy look to the -no letter/X/ or Y followed by a number below 39,999 (some 1 said March '77 was the last made) on the vin, Bill? I know vin & block #s don't replicate each other...

Anyway, that's alright if I'm wrong. My orig. question was just the basics. I don't wanna put the forum thru tryin to teach me the intricacies of code readin. And you've helped me with that:

a HD, (may B ) 63 or 67 - 2/28/77 4 wd F250, a narrower frame (33.5" v other 250s 4" wider) w/ D 60 in back, divorced transfer case. Variations had: married T-case, NP203 or 205; full X 4 wd or lock outs, light or heavy (8 lug) duty D44 - open or closed knuckles, or D 60 (called the D50 in this app) up front, discs (up frnt) in 75 or 6; ram assist power steering or manual, 9+1 or 5 pac leafs in the back.

All I need to know now is rear width "drum face to drum face" and same for frnt-"length". The tire mount to tire mount (i.e. measurement from same location frnt & rear axles w/o tires on). If tires are measured they can B different widths, of course, & throw it off.

Again, thanks for all the time n effort.

 

All those numbers/letters are for the 77 model year

Model year usually runs from August to July

The 77 Truck/car was introduced or in the show room for September just before school started.

The O (oh) was for early 77's and the X and Y were used in the calender year 77.

Any 77 f250 4x4 built after February 28th 1977 is NOT a highboy
