I have a 351m motor and was thinkin about makin it a 400 im my auto class this year. i was just wondering if it was worth my time or not. The 351 only has 90k miles on it. i have been told that all i would need would be a crank and new pistons is that correct?

 

Go to the 351C-M/400 thread there is all kinds of info there. But to give you a quick answer, yes, that is all you will need. John

 

why not just put a 400 in it they are out there i got one sitting on the garage floor that a jasper motor used and just junked one make an offer i would sell mine jpierce2004@comcast.net

 

yes it is worth it if you're looking for more power out of it
