Pictures of the engine pad will help a lot.
TO3497BB doesn't make any sense.
The block casting number and head casting numbers work for 1969 vintage parts.
The intake manifold looks like if could be a 1968 / 1969 vintage part.
Please post a picture of the front engine pad.

It seems the BB is the concern. I have tried to research the internet and can not fine this code. The block is for sure a 69 HP block according to all the numbers and the heads and intake is correct for a L88 but the front is a problem
thanks for your help.

I suspect that you engine code stamp is 7BB. A number of marine engines used a engine suffix code that started with a digit.
Another possibility is a rebuilder's stamp.
Seeing the stamp will help make that determination.

What the picture will tell us is the font and style of the stamping. Once we see the stamp, we can pretty quickly determine if this is a factory stamping or an aftermarket stamping.

The problem with the engine stamp, goes beyond the "BB". There's to many numbers in the stamp.
The "163" intake you have, was not used on the L-88. 68-69 L-88's used the "198" intake, and 67's used the "069". The "163" intake was used on 68-69 396/375's in Camaro's, Chevelle's and Nova's, as well as the 69 427 COPO Camaro's.

Big blocks made for marine applications, had a 3 digit suffix code, made up of a number followed by 2 letters. Unfortunately, I can't find any listing for a "7BB" marine suffix code. The vast majority of marine big block suffix codes had an "X" as the second digit, with "F" and "H" as the other most common second digits. There were no marine big blocks that had a "B" as the second digit in the suffix code.

Let dissect what we have here:
TO3497BB
T = Tonowanda (possibly)
O = is this a letter 'O' or a digit zero. let's assume digit zero
3 = March (month of assembly)
49 = oops, there are not 49 days in a month, any month
7BB = suffix code ???
Look at it another way
T = Tonowanda (possibly)
O = is this a letter 'O' or a digit zero. let's assume letter 'O' = ???
34 = oops, no month of 34
97 = oops, there are not 97 days in a month, any month
BB = suffix code ???
Seriously, a picture of this engine pad will help a lot.
