Hi Looking for correct L48 code MS for 67 RS/SS Conv 4 speed. date code for car is 11D
Be careful giving out your full VIN, scam artitsts will read these posts and restamp an engine block with your VIN and then contact you saying they have your original motor.
If you're just looking to get close, there's an MS block 7N151033 in the 67 Orphans section. I feel your pain, finally settled for one about 700 cars / two days before mine. Never will stop looking though. Seems those MS and MU blocks are pretty scare.
