I have an early production 67 mustang with 200 in it . It is stock as far as i know except i have a weber 32/36 2 bbl carb and headers on it . As it was restored i put 8 inch rear end that has 2.79 ratio . On hwy it does ok but has no low end get up . Any suggestions for some low end get up ? What RPM does the 200 like for cruising down road ? Usually run around 60 -65 on road . Thanks for any help!!
