Hi
I am new to this forum and recently purchased a 1971 Mustang convertible with
"M 351C-4V" which I found online has:
"The 1970-1971 M-code version (300 HP/1970, 285 HP/1971) was a high compression 4V configuration employing closed-chamber head design and hydraulic lifters."
The car is great and runs well, but has its original manifold.
I am thinking about putting long tube ceramic headers on to increase horsepower and improve the exhaust sound.
Do you recommend it? Is it worth the money?
Thanks
