i personally would like to get a few extra horses and some more torque, im runnung an ** 306 engine and 456 gears, im up for as much "free" power as i can get, i say free power meaning the few things i have done, like headers and exhaust, electric fan swap, k&n intake system, all the stuff that only makes power and improves gas mileage, iwas thinking some roller rockers and maybe some lighter pushrods? id really love and upp,lower, and throttle body intake system but all i have seen is around 800-1000 bills for a freakin intake, thats just insane if u ask me, im always open to any fuel saving or power gaining tips
89,
Sounds good and you have most of the basics in that 306 already, and since it is a ** variant, it should have da roller rockers in it.
custom push rods go for about $180. a set aftermarket or
$125. from Ford Racing; have to check valve spring rates, etc w/lighter wt rods....maybe a complete kit?

excellent info Links Source for SBF's and esp following:
Power Combinations- a good overview oftorque vs hp needs, dd vs drag racer, etc. w/specs on lift, etc.
Ron Morris Performance is a good info source too
esp.: "...The Explorer engines have the best intake manifold, it is great for a stock or modified engine. When run in a dyno test against the Cobra Intake manifold and many after market intake manifolds, it performed just as well as if not better than the other intake manifolds. Explorers come from the factory with 65mm throttle bodies, but require a linkage modification when installing them into Mustangs or Broncos. When using this engine, it is best to convert to the 89-93 Mustang wiring and computer system.
The Explorer uses a distributorless ignition system and EEC V fuel injection system. This EEC V system has a great deal of emission control devices and is difficult to work with in an EFI conversion.
I recommend changing this to a 89-93 Mustang ignition and EEC IV fuel injection system. The EEC IV system is easier to install and has a lot less emissions equipment.
Early Explorer engines (1995 to 19971/4) came with GT-40 Heads, easily indentified by the 3 vertical ribs on the front and rear of the heads or the "GT" cast into the corner of the head just outside the valve cover. These heads have stock spark plug angles, location and will work in Early Mustangs with all common exhaust systems.
The Late Explorer engines(19971/4 to 2001) have GT-40P cylinder heads, easily identified by 4 vertical ribs on the front and rear of the heads or the "P" cast into the corner of the head just outside the valve cover. These heads do require special headers, they have a different spark plug angle & location and may interfere with your exhaust manifolds or headers. Check spark plug clearance before installing these heads or an Explorer engine.
Both of these heads are great heads, they will out flow and out perform stock late model Mustang heads..."
If you can reduce weight...I believe justshootme has a wt red. effort underway...ask him.
ch out some HP to WT figures and see what 100lbs of junk in da trunk + to HP (think it is = 5 HP)
gl! have to work for food/gas $ now
