I wish, but no.

They had the bolt pattern of the R5 block on file. But the starter and flywheel is different.

This bell uses the standard size 130 tooth flex plate. The starter position is in the exact place they are on a 340. Just something to not have to buy when making the. Change to R5. The depth of the bell is also important. No starter spacing or flywheel spacing issues. Bolt it to a Reid ultimate case with a standard powerglide converter, use your existing mopar starter and everything fits the first time.

This was important to be this way. I have raced mopars for well over 20 years. Every time I buy something there is a surprise. You have to alter something or buy other parts to make it work. I am doing everything imaginable to make sure this does not happen. And later want to come up with plates for use with the NASCAR motor plate. A single stage off the shelf kit to convert to wet sump oiling if some one desires. Some day headers.
