Here's what I have, from the PV I could only tell that it's an HL block built in Tonawanda in '69. Has a 2 barrel and 2 bolt main. Is this the run of the mill passenger 350 or a motor out of a CK? wondering how many ponies this motor would have come with. TIA
69 HL shows to be a 250HP 350 out of a passenger car. http://www.nastyz28.com/gm-chevy-codes/chevy-engine-codes-suffix-5.php Larry T
