BlueHemi,

Thanks sharing the info!  So what's the conclusion (if any)?

  1) 69 & 70 blocks are both the same?
  2) Both have a special code cast on the front (driver's) side of the block that reads: HP 429
  3) Both had VIN stamped on rear (driver's) side of block (partial VIN of 8 #)
  4) Both have a vert. C9AE casting number along the passenger side of block somewhat near the rear.
  5) Both have 4-bolt mains on journals 1, 2, 3 & 4

*) We have one 70 block that has a the letter "A" cast in place of the HP 429 cast.

**) Replacement Ford Blocks have 460 (reversed/upsidedown) in place of the HP 429 cast. - I would think their date stamp would also be later than the build date of the car..

***) There seems to always be exceptions to the rules...



I have seen several 70 cars (original engine) with the letter "A" cast where the HP 429 would be on a 69 car.  Only a someone like Steve Strange would know where the cut in point is.

Wow!  you guys really go to the extreme to get good/reliable info out!

Thank you!

Can the VIN # on the engine be read while the engine is in the car? Say maybe using a mirror(like a dentists mirror on an extention or something)
...or is it impossible to see the VIN once the engine is in the car?



It isn't easy but you can read the vin lying under the car on the drivers side with your head under the tranny shift linkage
