will 351c headers fit a 351m? Which are better shorty or long tube? thanks

 

a definite maybe. headers intended for 351c 2v heads will bolt up, but may or may not fit the rest of your truck.

long-tube headers of smaller diameter are generally better for low end torque, while fatter shorties are prefered for higher rpms.

 

thanks do you know where to get shortys for a 351m

 

I don't know if they are considered "shorties" or not, but I bought some from Jegs last week made by Dynomax that were only $105. They don't have very long collector ends at all, I have seen much longer on Cleveland motors, but I have also seen shorter on 5.0 engines. I am sorry that I don't know about the shorty part, but if you want the part#, you can call Jegs and ask them. Also, these are for a 2WD pickup.

 

i put a set of headers in my 77 f250 4x4 and i had to be the exhaust down below the cross meber because i used a set or 2 wheel drvie headers. do for get to take that in to consideration.
