So I have a 96 explorer 5.0 I'm looking for a bit more tq, should I go with 1.7 roller rockers or a cam?
96ex5.0,
Here's a brake down for you
Roller Rocker Positives:
Easy to install the rockers arms
Some gains in TQ and HP
Roller Rocker Negatives if EFI:
Have to install taller valve covers to clear rocker arms
Have to install phenolic intake spacer to clear valve covers
Hope you have enough clearance between the intake manifold and hood
Camshaft Positives:
Noticable gains in TQ and HP
Friends with be impressed you changed the camshaft
Camshaft Negatives:
Pain in the ass to do
Alot of parts to remove
May need special tools (to remove fan clutch and broken bolts and studs)
May need new water pump (depend on mileage)
May need new water pump bolts and studs (depend on condition)
May need new timing cover (stuck on due to mileage)
May need new timing cover bolts and studs (depend on condition)
May need new timing chain and gears
(might as well replace it since you're in there)
If you went to crazy on the camshaft you may need to reprogram your ECU
Enjoy your project which ever way you go.
