contact shaun @ crowler
I do not think I ever cam doc'd the 267 or 271 crowler
Crowler may use .005 so would be longer than comp but shorter than crane for the same lobe- ask shaun
Crower / Engle are proven designs and not as fast as the comp HL grinds (or howard?)
the fat cams with the lift rolled over wear very eell
The heads they were dsigned for did not flow more wth higher lift so why push it into pointy nose territory
they work well with stock manifolds
for Krooser's car i'll have to look
I do ot know if he bought springs yet
he recommended one beehive but Krooser has long valves so needs a different sprng
