Flathead V8 manifold question.

Other than being able to retain the stock generator position, what is the benefit of long risers, as on a Thickstun PM7 manifold?

 

Ummm....Horsepower.

 

Wow, Thats it?

 

I've run a PM 7 for about 15 yrs but I found that although it looked neat, with the real tall stacks, the carbs had a hard time heating up to operating temp and I felt the fuel didnt atomize correctly leading to a rich mixture. I think that if you live in a warm weather climate it might be less of a problem but if the temps are in the 60's it takes a long time for this intake to warm up. I recently changed engines and used the shorter offy style intake and found that my car ran much better especially around town and a traffic speeds.

 

this makes perfect sense! a true HAMBER answer!
