x code engines were not sold to the public, they were sold to factory race teams. up for grabs is , as listed , 375hp, 327, small journal, 2 bolt main. i tore it apart to see how it looked when i bought it. it will need to be bored at least 10 thou over, and crank turned 10 thou under, due to light surface rust. engine has been stored properly for the last 20yrs, and has an aluminum flywheel. $700. takes it. i,m in sudbury ont. i will post casting #,s and serial #,s later 2nite. the serial# is what sets it apart from all other sb engines. call colin @ 705 525 8995 here,s the #s 7n217651 v0427ms

Is the X in the suffix and at the beginning of it or at the end? What are the casting numbers? The only high HP that I know of is the 365 HP 327 64 Chevelles (L-76?)
I had a 65 365 HP 327 back in the 70's that I got of a guy from the Timers car club that used to race it . Loved that motor. The 375 HP 327 would be a FI vette engine. Its the Fuel injection that makes it 375 HP. Carb makes it 365 HP. Thats the only difference in the two engines. Same solid cam, same 11 to 1 pistons same heads. I guess only way to get a 375 hp 327 engine other than in a vette would be over the counter.

Same here, my '65 nova had a transplant from a '65 'vette, engine was apparently the 375 hp edition, but had an aluminum intake added, along with a 780 holley. Solids, hi-comp pistons, and unreal revving power, I used a 7500 rpm shift point on my SunSuper, and with 4.88 gears and a 4 speed, I'm sure it went even higher on those, umm, oops, missed shifts!
where the exper. motors are traceable is all through the serial# not the casting, as the castings were used in a variety of vehicles, from trucks to vettes. this engine is all on a vette specificaction, and then sum. the 375hp rating was a ball park. some say its alot more.

Does it have domed pistons ? Can you post the crank casting number.
That 3892657 block is a 67 block used on 327 302 and 350's. The vin also indicates this as 7N217651 the 7 is the year N is the final assy plant for the car Norwood . The V0427MS is the motor ID V is the engine assy plant Flint engine plant 0427is april 27 th the MS shows as a 295 hp camaro 350 . The heads 3890462 are also a 67 camel hump head. The crank casting numbers will tell the tale if a 67 327 or a 67 camaro 350. That MS could be wrong.

i had to go through about 5-6 different sites and combine all of the info gathered to come up with the x code label. i,ve never heard of those #s being wrong, but also am not an expert niether. all of the parts are vette style, from raised dome pistons, with valve recessions, steel crank, and aluminum flywheel all lead towards my findings. with all of the knowledge here on this site, i,m sure we,ll find out exactly what it is. i,ll post the crank#s tonight.

niether, its decipered through the serial #
Serial where? As far as I know The suffix is the serial number. The numbers on the front pad on the passenger side. What am I missing because I have a X code motor also.
The MS code was also used in the 68 nova line also the FX at the end is relating to the body style it was in F for camaro and X for chev II. The block was also used for the start of the 68 chevy II year 350.
If a 327 or a 350 sounds like some one built a healthy motor for racing back in the day if it had high dome pistons. Would have been a great block for cheating in the stock class back in 67 as unless you tore it apart you could say you had a 327 when infact your running a healthy 350. Must of drove the tech's nuts.
All Beaumont4008 has stated above is exactly what I get from the above posted #'s too and the same as what I was going to say although probably expressed much more clearly than I could've!.
And isn't the info Carl posted above re the X & Y SBC info more relevant to early 60's GM experimental engines such as the alloy engine used in the XP819 etc?.
Also some pre CE engines had X-Code Suffixes and may be where some of the X engine legends have originated?.

So if I had a 65-67 casting motor with a X2729 suffix it could be a CE type engine?

Glad you got what you wanted for it. The heads alone are worth a few bucks. I think if you post the crank casting part number will tell alot more about it.
