I just aquired a 1972 351 block and i know those early years were "better" than late model blocks...what is the general consensus of HP limits for that year...Im sure the knowledge is here. The search feature is like a needle in a hay stack.

What do you guys think??

 

I think there are some people that easily have done 600 hp out of them

 

I guess 1969-1974 are the money years...for those of us who cant afford SVO technology...lol Was looking at 427 N/A...FTW

 

50-60hp more IF your luck and if you are building a run of the mill 400-450hp engine and plan on using stock hyd roller lifters, the early block is way more hassle then warranted

 

Actually woodsy im getting ready to order my 427 kit from you maybe tomorrow i just got my block today and havent measured the bore to see what ill need. It is a solid roller Huge cam and TFS "R" heads...should be WAY more than 450....fingers crossed. Basically everything in my Sig except 427...

 

Wow, I was watching the cowboys get wasted, I thought you were inquiring about a 302, ANY year windsor block will go 700-800 with the right builder. In your case the block is irrelevant as you are running a solid

 

SWEET any chance ill be in that neighbor hood???
