Cam suggestions???

[Mr. Land Yacht]

I could get high 14's?
AWESOME!

BTW, if I bore out my block to 306, does that give me any hp increase at all? like 2-3 hp?
and...if I had to put in 24lb injectors, how much would it cost me to get a MAF ECM tuned for them? just wondering

1500, thats an explorer motor

There will be some slight increase, but it would not be much. By the time it is cooked/cleaned, bored and then new cam bearings installed, you could be looking at $175 or so.
You should just buy a new MAF sensor which is calibrated for 24# injectors. Nothing has to be done to your HO Mustang ECM.

do you guys think it's possible for my car to run high 14's if it's got about 300 hp, 2400 stall converter and a shift kit? or am I over shooting it?

Been there done that with 100hp LESS.

And I was wrong about my old stall converter...I ran a torquemaster 2000, not a 2400..

With a stock 250K mile lopo shortblock I ran 14.86 with 3.73's, 2000 stall and a stock ho cam & intake. Heads were mildly ported. Car was on a slight diet though. Not too much removed.

[Mr. Land Yacht]

Wow...that's cool!

say, are these the right rings for the Kieth Black hyperuetectic pistons with 4.030" bore?

Those should be the correct Moly rings. If you go with that, it is critical that the bores are finished very fine for the Moly top rings. 400 is a common Moly finish grit.

[Mr. Land Yacht]

ok..thanks.

[Mr. Land Yacht]

Does anyone know the RPM powerbands of the E303, F303 and X303 cams?
and...
are roller rockers better than the stock rockers?(1.6 ratio)

[88MercWagon]

The powerbands of the cams are posted on the Ford Racing website. If I remember correctly, the E303 is the mildest, making power idle-5500, the F-303 is midrange, about 1500-6000, and the X-303, is a street/strip cam with power between about 2500-6500. Hope this helps, and that my facts are straight.

[Mr. Land Yacht]

I just found it
here's the site...http://www.fordracingparts.com/parts...tKeyField=1329
it says that the F303 powerband is 2800-6000 or am I reading it wrong?
is the beginning of the powerband the peak torque?
oh, and do I have to put on roller rockers if I get a hydraulic roller cam?

[turbo2256b]

The F cam is only good for a gain of 5HP at peak and losses at low end. X puts the power way up massive loss at low end F annd X would also require that expensive torq converter. Your cork with the E camm annd ported heads is going to be the intake not the cam. Next is your fuel system. My engine flows 210 through the intake thats over 430 HP at 6000 RPM. When I figured innjector size to keep stock system pressure it needed 40# injectors. Bigger fuel lines bigger fuel rails bigger fuel pump. I went carbs for that reason or aftermarket TB injection. RPM rangess are listed for factory heads stock air flow your going to have killer flow andd air speed let it do the work stick with the E cam. It will have the broadest RPM power band.

[Mr. Land Yacht]

ok...so...E303 cam is teh best for my application...
if I put on 1.7 roller rockers, would that change the powerband?

[turbo2256b]

IT will but not all that much they increase lift and duration a bit.

[Grand Marquis GT]

The E303 is your best bet... but I would still consider maybe even a custom grind comp cams stick..

[Mr. Land Yacht]

ok, I'll go with the E303...
