any negatives to running a 4" crank? i am puting in an order for an eagle crank, rods and some boost pistons soon.
other than the $900 and reduction in miliage are there any other reasons against a 4" stroke? i know the question of more stroke in a FI set up has been thru here before and from that i got that more cubes is always better, just want to see if there are any negatives that i am not aware of yet.

As you devise your setup I would make sure all the parts you are getting make sense to go together.
A 4.000 crank will give more cubes, more torque so you could in my opinion run lower compression like 8:1 and get away with a lot more power on pump gas.
That's pretty much the only reason I would do that except to run a forged crank.

thats prety much where i am headed, i like the 8-1 idea but almost everyone i talk to says that is too low. sounds like the best reason to go with very low compresion is more power with pump gas.
