LB 65 396 Impala 325 L-35 Power Glide 4-Brl Holley
LB 69 427 Impala 335 LS-1 3 Spd 4-Brl
but neither corresponds with the 1 in the VIN (1971)
Get the block casting number and casting date.

Just noticed the 0 in the code you posted -TO8250 LB
Take another look at that code and see what that 0 really is -a C maby?

Its really hard to tell. What if it was?

Tom
1971 engines had a three letter suffix code. CLB could be a 71 LS3 engine from a Chevelle w/TH400. Like the difference between the letter 'O' and the number '0', big difference between the two.

{Edit}The partial VIN of 11k111445 would indicate a 1971 Chevelle from KC with sequence number 111445.

Took the hood off to read the number on the back of the block. Here's what I came up with.

Totally confused now.
