You've got what is probably a home built motor. The 3932388 block is a 1969 heavy duty block found only as a 302 or 350 with 4 bolt mains.I have a sbc the casting number is 3932388 and it has 882 heads. Does anyone know what this came out of? It has a performer intake, holley 600cfm, long tube headers, 4 speed saginaw. Thanks
This is a Canadian engine the K is St. Catherines, Ontario. The 0820 is the month and day August 20th. I can't find where my suffix code book went so I can't break the FR. But GM of Canada is a different horse from GM USA and I'm suspecting this may be a 327 as that what most but not all American F code engines were. This doesn't match to the casting number, but one needs to remember that GM was making large journal 327's in 1969 and there is nothing to prevent this casting which is a 4 inch bore from being made into a 327 although there are people who swear GM never built a 4 bolt main 327, I have learned not to put anything beyond GM. Then again there's nothing to say this block didn't get finished with 2 bolt mains. I cannot get that VIN to decode, does that number string match the vehicle id plate? If so what figures are ahead of those 12 numbers.It looks like it 192200056644 and then K0820FR.
The casting 3932388 is simply a 4 inch bore casting. Yes the casting 3932388 can buld an LM1 but it can also buld a large number of other engines. The books say it's used to build 302 and 350 engines which would tell you it can be used in high performance or heavy duty engines. That doesn't mean the casting isn't used for lesser stressed applications. The difference in displacement is simply the stroke 3 inches for a 302 and 3.48 for a 350 or 3.25 for a 327. I wondered aloud about what it is seeing that the casting was made into an engine in Canada. Plus the chunk of VIN you have looks Canadian. Like I said GM of Canada marches to its own drummer, you can't just take USofA codes and apply them, sometimes yes, sometimes no. I speculated on the possibility of a 327 because the vast majority of two letter F suffix coded engines are 327s. The 327 also uses the 4 inch core block so this isn't outside the realm of possibility. I cannot find where my Canadian VIN code book went so I can't definitivly help, I tried on the internet and inspite of that appearing to be a pre 1981 code it will not unwind in any decoder I've tried, I also cannot find an FR suffix code. Two letter American codes starting with an F only connect as a 1969 327 for various apps from Corvettes to cop cars. Whether that can be applied to Canadian engines I do not know at this point. The only FR suffix code I can find for 1969 is for an inline 6 which doesn't fit at all. You can always pull a head and measure the stroke. Right now this is off the map in that the available data doesn't fit the description you were given.block casting is 3932388. I was told it was a 350
I have a 4 bolt main 327 that was in a 69 Camaro. I thought that was fairly common?This doesn't match to the casting number, but one needs to remember that GM was making large journal 327's in 1969 and there is nothing to prevent this casting which is a 4 inch bore from being made into a 327 although there are people who swear GM never built a 4 bolt main 327, I have learned not to put anything beyond GM.
