i have read alot about 4-7 swap...
is it really worth the effort?
some of the BESt engine builders in the country dont seem to think so. no matter the order you have 2 side by side firing. some say it changes the deflection on a weaker crank adding a few ponies , but a good crank, no help.. im interested in what you experience




The 4-7 swap gives you the old Ford flat head firing order. The 4-7, 2-3 swap makes it the same as a Ford 351W firing order.
