400 stroker build....for a boat

A thread that may be of interest......
Chrysler crank pump drive drawings 318 to 440

Thanks for the link! I am a member over there as well, and have scoured the pages looking for info that would help me. The person that originated that thead was actually the one to suggest to me to use a 400 block instead of a 440. He is also the one that suggested using the SB chevy manifolds in place of the old Chrysler ones.

Sadly I have not been able to get a hold of him recently to bounce ideas off of.
