i looked for the same thing approximately 2 years ago. no luck. could not find anything that interchanges with the 351c. if i was told correctly and i could find no info otherwise, the 351c is the only one that does not run coolant through the intake manifold. you will have to fab one to suit you.
good luck with it ,clevelands rock!
