Hello, I have a 66 ss and have a few question about the engine numbers, the casting # is 3855961 on the engine pad is T0607EDHG133212 the 133212 matches the vin. and the block casting is E-10-6 the intake manifold #'s are 3866948 and is a holly carb. is this a 325 hp or the 360 hp? and do you think this is the original engine for this car?. also on the trans. its a muncie with the vin #'s (133212) stamped into it is that normal? thank you.

Yes, they are original to your car..All of the Numbers match the VIN!! E-10-6= casted May 10th 1966. Engine suffix code ED is 325hp 4speed holley. Sounds like a great find!

thanks, I thought it was legit, but its nice to here it from someone else. this car has been sitting in a barn since 1975 shows 14,509 miles (trying to get that verifed) it still had bias plys on it when i bought it. thanks again.
