Thread: Have heads (kind of) now what?

Tweet

I'm a little confused.

Dart claims the 200's are "ideal for 383-400 where excellent torque is desired without loosing the ability to wind it out occationally" The 1.437 double springs are 130#@1.800"/.620 max (Comp cams 987) They also have 1.250 single and 1.55 double available. If the 1.437's are wimpy why do they even offer 1.250's?

I really apprieciate all the input Im getting on this as I'm just learning.

Thanks again,
Sean
