Where to Find Specs on Old Integral Recips?

Where to Find Specs on Old Integral Recips?

Hi guys. I am doing a project involving some ancient Clark RA-32's. I am in need of performance data on the power end and the available cylinders. Where does a guy look for data on these old recips?

Thanks guys! Pete

i "believe" i have some old documentation for various clark, cb, worthington, etc. engine data, but it is at home. i get home tonight - hopefully, i remember to look.

some info in above link, but i think not what you need.

good luck!

RE: Where to Find Specs on Old Integral Recips?

sorry, i cannot find the documentation. probably lost it when hard drive failed.

try contacting one of the gas transmission companies as someone knows someone whom will have the engine data.

It may be worth giving Dresser-Rand Painted Post, NY tech services a call. They still maintain many records and information on the Clark Brothers engine lineup. If you have serial numbers available, they should be able to help you out. The information I have access to is limited.. Feel free to email me: and I can put you in touch directly with our integral engine team.

That was a nice response. Site management prefers that we don't include linkable e-mail addresses in posts because it encourages some bad behavior by the bots. If KernOily has gotten the word, you might want to edit your post and pull out your e-mail.
