casting dates

[Jerry K.]

I have question about casting dates on my 300hp intake manifold, how close to the engine casting date should the intake be? My 1962 was assembled in St. Louis on June 27, casting on the block is April 3,engine assembled on June 13.
I need a new intake anyway because of crack and the repair would be visable.

My 65 250 has an H 5 4 intake on a H 8 4 block.

Re: casting dates

The major castings were in inventory at Flint and pulled rather randomly for engine jobs sent down the line. Like other dated parts, there was no specific FIFO/LIFO inventory control so there's no 'right' answer to how an intake manifold date should correspond to a block casting date...

Basically, you want the dated items to preceed the engine assy date shown on the stamp pad with all preceeding the car's final assy date by a 0-6 month interval to judge without deduction....
