351w vs 351m

[goinbroke2]

Thanks for the replies guys.
Yes '75 was the first year of small valves. Just happen to know where a 77 Torino with a 351m is and it got me thinking. Both have the 1.21 carb, I just thought maybe the bigger valves and ports would be better. My biggest concern with the m would be the crappy oiling system and having to run stock cast Pistons.
As far as the factor I thought I saw both at 230 and the 400 at 240.

Anyway, after reading the thread about reducing hp 20 percent it sent me looking through the guide and kijiji! Lol! A 351 at 184hp might actually be able to hit the index with enough work, 230? Not a chance.
