Check out the flf part real good because I dont have anything like that. I have a ton that are one letter off of it in many combinations. What year do you think it might be? Don |
Re: Please help decode my motor
the FLF part is correct. Just the numbers and letters below I can barely read. No idea what year it is,thanks for the help

Re: Please help decode my motor
V=Flint Engine Plant
04= April 17=17th As far as the FLF goes there is no such code . It may be a TLF or a BLF TLF= 1978 400c.i. BLF= 1990 305c.i. Oter possibilities are: FLH FLJ FLK FLL FLK FLM FLR FLS FLW These are all 85' 350 codes You might want to go by the casting number on the rear of the block. |
Re: Please help decode my motor
which side on the block,pass or dr side,near bellhousing??? I will get it,is it hard to read or get at???
|
Re: Please help decode my motor
I would check the driverside first then the passengerside. It is difficult to access. A mirror helps. If you can clean the area off, a piece of clay to make an impressoin helps too.

Re: Please help decode my motor
ok I will check, let u know tonight what and if i find anything, thanks...i am :confused: and :crazy:
|
Re: Please help decode my motor
Dont get your hopes up. It's not a 400 most likely not a 350 either, it's a moslt likely a BLF 305. is your harmonic damper (ballancer) 8in or 6in?
|
Re: Please help decode my motor
ok this is what I got from the drivers rear. "4010207"
The only nuber that is questionable is 401?207, maybe an 8,2< Not sure,best guess was a 0. Very hard to see back there............Maybe I was misled when I bought this truck. Was told it was a 350 |
Re: Please help decode my motor
which side is your dipstick on?
almost always the 305's were on the pass side with the exhaust manifolds that came up even with the valve covers instead of below the spark plugs |
Re: Please help decode my motor
My '86 305 actually has a big "305" cast into the block near the front in numbers about 3/4 in tall. You can see it from underneath, I think on the driver's side. You might see if yours has that.

Re: Please help decode my motor
GM Engine decoding list...hope this helps anyone else out
Engine Block Casting Numbers Notes (for below): "High Power" is the maximum rate HP this block was used for, "Low Power" is the lowest rated horsepower RPO engine the block was used in. "Main Caps" is the number of bolts holding the cap. A "two-bolt" main, or a four-bolt main. Four bolt main blocks are desirable in high performance applications because the extra strength of the additional bolts keeps the bottom end rigid and less prone to failure. However, a properly prepared 2 bolt main engine will work just fine (often times you'll lose a rod bolt before you break a crank because it's "only" a 2 bolt main).

Re: Please help decode my motor
weird thing is....dipstick on pass side, and I double checld the numbers 3 times, its a 350, 4 bolt main. truck motor, it may actually be the orig motor. I was told its 60 over,roller rockers,400hp. I believe it cause this truck is fast.

Re: Please help decode my motor
my motor has a 5.7 raised numbers on the passenger side behind the head facing up just before the tranny and block join together maybe that will help also b/c you still sound doughtfull sp?
