used in > .le-mans & can-am. < also early prototype Canted Valve IDA type XE 244963 race heads specificly made for the windsor blocks mistaken by some as a cleveland block head which they were NOT. This head was suppose to be in development by H-M for larger ci > .can-am Windsor blocks. < as i understand the G-W heads being used at the time apparently? did Not flow enough for the bigger 351+ci sized stroker engs...

<
notice the few odd similarities this head casting had to the > G-W head < casting of the time

351w xe 93532 prototype heads.jpg


the XE race head designs were again the original grandfather to the Boss 302 & later 351C heads.

I understand there were over 50 351W type XE 93532 blocks cast with over a dozen ending up with drag racers and more with nascar, circle, road racers when the can-am racing program was dropped by Ford, also these older 351w xe castings did use xh 3.5"-3.7" steel stroker cranks and is where the later 351c got its 2.750" main bore sizing / spacing from. The 351W engine has a much earlier history as interesting (maybe more so) to which some have falsely credited to the later 351C engine, the 351W design is far more than just a "truck eng".

... old 351W xe race blocks are worth what someone is willing to pay for them, there are better/cheaper blocks today to use like the > 351/451 MAXX < blocks

Engine is in Ireland, but came from GB, supposedly from a race car many years ago, quite possibly from a GT40, Mirage or a Gurney Weslake,. being a race engine on this side of the pond. Not quite sure what to do with it! Not my area of expertise. Probably ideal for someone restoring an original car maybe?

IMO, all these old xe race blocks should be retired from racing abuse to save there history

it was not a real race but more of a parade, driver did not want to thrash/hurt it after restoration and kept rpm low.

The 351w xe block was only good for about 600hp before block main web cracking problems started because bulkheads needed to be thicker.
Dyno Dons 400+ci match race aluminum 351w xe block was welded and rewelded many times over because of over powering it.
Fords 351ci can-am program was just too short back then for any real R&D to have taken place, a real shame of what could have been a winner.

Never seen a race driver holding the steering wheel that way on left hand bends, and seemed to be lost finding gears, For a Demo run it is fine, but way out of order in control of a valuable race car, unless he owns it?

i really loved the look of can-am cars as a kid and still do, a shame Ford / Shelby did not stay in can-am back then developing the 373w - 393w ci xe stroker race engines more, unfortunatly all of them had issues/bugs to be worked out in the first year. Apparently Shelby was pissed off with the whole can-am deal.

you might enjoy these 1967 racing vids with a few different 351w xe stroker engines running in them, both vids linked to the 351w/393w stroker Honker ...

just wanted to add another XE Windsor part #150985 to this thread some dont know about, Ford's own pre production ... Canted Valve Windsor Head ...
again this head is NOT a cleveland head but another late 60's 302w/351w head, this xe Windsor head did not make it to production because Ford could not get this small port 2V type head to flow well so they dropped the R&D on it and instead went with the larger port 4V Boss head...

Ford had plans to use canted valve head designs on 302w/351w blocks Before they used them on the later cleveland block

btw, notice the L shaped 351w type intake/water ports on heads above ...

302 vs 351 ..jpg

. 302 vs 351.jpg


imagine heads above on a 1969 4V int Ford 351 C9 4 bolt main W block as a 351Clevor that was close to being a production engine.

...also on a side note for those that dont know...

in 1969 Ford Indy developed small ci > INTAKE PORT FILLERS < for the 4V Boss head Long before anyone else did.

I have an XE 302 based crank. I'll have to get the part number later. I always wondered about it.

I think the 7.3 is the way to go on pretty much anything now. That crossbolt block should take pretty much anything you throw at it.

My 302 crankshaft is XE 124499. Nearest as I can tell it's 3.00 stroke.
