Ya that seemed to hold good in that video. Your max rpm is the low 5's?

On 91 i spin 4900-5000 with this impeller. On the race fuel i was seeing 5200  for some reason.

i keep one tank filled with 91, the other with 110 for the bottle.

im in the low 6's on the bottle

FordLover,

Do you have any blueprints of the Ford 385 series engine, showing bolt hole locations front and rear, you could share?

Thanks in advance,

Joe

I dont believe I have that in my paperwork. Have the build sheet with the details of the parts then a balancing sheet with the weights and clearances of everything.
