I wonder if you're not allowed to post more than 5 times consecutively?

Or upload a word document?

Hey Ryan, can you get the specs on the cams as well?

I don't have much on the cams. However, I do know that the 96-98 cams are the more aggressive of the stock cams and Mach 1 guys have reported gains of 15-20hp from a swap.

 

[01yellerCobra]

Hmmm....I didn't think the cams for B heads would work in the C heads. Learn something new every day.

 

[68Stang]

Yeah, the asymmetrical lobe profiles help with swirl.

Hey, I forgot I had posted this:

03/04 Cobras, Navigators, Mach 1s, Aviators and Marauders all use the same intake cam and it is less aggressive than the 99/01 Cobra cams (which btw are identical). Additionally, the 96-98 Cobra intake cams are even more aggressive than the 99/01 Cobra cams.

The 96-98 cam specs are:

intake primary lobe 196@.050/.397 lift
secondary lobe 206@.050/.397 lift

exhaust 196@.050/.3937 lift

99/01 cams specs are:
intake 196@.050/.397 lift
exhaust 196@.050/.397 lift

2003-2004 cams specs are:
intake - 186 deg@.050" - .397" lift (Navi intake cam)
exhaust - 196 deg@.050" - .397" lift

All are on a 114 LSA

Would I be a retard to try and take the early "swirl port" heads from a Mark 8, plop them on a 5.4 truck block, tig weld the stock mark 8 intake to be wider, and run it N/A.

Any comments. There is a junk yard around here that has about four of those early mark 8 engines in it right now. $150 complete w/o accesories.

If you want to throw on a set of 4V's, I think you would be better off with the Navi or Mach heads. Which are the same as the 03/04 Cobra obviously. But they're designed to build torque in a N/A form. This is just my opinion of course.

 

[68Stang]

Even 03 Cobra heads are a good N/A head, you'll need the C intake thought. If you are going for all out N/A power, go with C heads or newer. If you are going for boosted power, the B heads will work great.
