03-04 exhaust cams to replace intake cams?

[mattdohc]

how much hp/tq gain is this going to be good for? myself I like the feel of the supercharger stock heads.

I'm not sure about power increase, but the sought-after 96-99 Cobra cams have equal duration at 195/195 while the original Marauder cams are 185/195. All of them have the same .398 lift.

If you get the degreeing correct, I think around 20-30rwhp for 96-98 cobra cams. Look around svtp, they come up every so often.

Hopefully massacre noticed this thread. He's the master on this and was instrumental when I swapped 98 cobra cams into an 03-04 cobra engine.

I would just either advance/retard the stock cams or use '96-'98 Cobra intake cams. Running exhaust cams on the intake side sounds overly complicated and time consuming IMHO.

I have a stash of Cobra cams, just waiting for a future project. Luckily I got mine when they were still cheap. Todd Warren was one of the first to put the early Cobra cams into the C heads, others on the corral and modfords were early to that party as well.

Well, it looks like I was able to grab a set of 99 Cobra cams after all. Anyone know where to find the cam bolts for them?

The dealer keeps them in stock but as mentioned ARP is the way to go. Summit is normally my go to.

I believe the cam covers are different. PCV location? Oil pan and pickup tube, too.

Yep basically everything except the long block is different. I'm going to strip this one, clean it good do the intake cams, and yank my to swap everything over. I'll be selling everything I don't use. No space for 2 motors come summer.

Good move. I have a spare engine ready to go. Low miles, Cobra cams. Just have to swap over cam covers and intake. It already has the correct pan and tube. The original engine is still doing fine at 281k but one of these days I suspect I'll need to change.

Exactly. Once it's done I'm going to take a long holiday weekend and swap it all over. That ticking is driving me crazy.

I am building a 4v engine with a teksid block, 99 heads and cams, with an 03 marauder intake. Yes, the non marauder valve covers will have ports in different spots but can still be used. I am in fact using the MKVIII timing cover as opposed to the Marauder one, it will work just fine. I got lots of advice regarding cams on this site and the CVN site. New oil pan, new tensioners, new oil pump, degreed the cams (116/110), it's been a fun, if not illuminating process.

I hope you meant 110/116 intake/exhaust if they are Ford cams
