A-65-8 75 hp what is it?

[tophand]

That engine I'm selling this question came up and I don't know the answer.
I have an A-65-8 with the 75 hp mod. It has a log entry that reads.

" Installed 1A90 prop. ser # 3498 making engine C-75- , 75 hp conversion kit previously installed" then signed by the A&P.

so....What is this engine? A-65,A-75, C-75, or none of the above.
I don't believe you can change an A model to a C model
I did post this on the RB (first time in over a year)

thanks.......Mike
