Re: 1969 L-72 For sale
Sounds like a 454 block to me.

Re: 1969 L-72 For sale
That was my first assumption as well. Late model 512 blocks were used as early LS-6 blocks. The crank shows 427 stroke. Everything on this motor is built to L-72 specs. 11:1 compression NOS pistons, crank, dimpled rods. I did not check to see if the jugs were notched for the 454 throw when the motor was assembled or I could give you a difinitive answer on this. Engine was originally built for a COPO in SLC, Utah, then the owner found a genuine COPO motor and put this up for sale. I bought it, did my homework and believe it to be a late model replacement 427 or CE motor.

Re: 1969 L-72 For sale
That makes since. What was the number on the crank?
Thanks, Jason

Re: 1969 L-72 For sale
I am not sure of that. I should have looked when the engine was going together but I did'nt. I was there when the short block was assembled, I wanted to make sure the guy didn't cut any corners, which he did't. I have a lot of respect for the builder at this point and believe him to be honest. He informed me that this was the 427 crank and I don't have any reason to doubt him. In all of our other dealings, he has been very staight up.

SSNOVA guy: CE blocks were used for L88 replacement shortblocks at that time! I have one with all the original std GM parts still in it! 512's were both at the time
