Default EPS 236/248 questions

Hey guys,

I have a few questions regarding this particular cam...
BTW i have searched and come up with a few threads but not many..

First, how is the driveability / street manners on this? I know that tuning will make the biggest difference here, but with it being tuned how does it act?

Second, will i need to check valve springs every 10k miles and change them at 20k (not factual numbers but just some i pulled out of thin air). I do remember the EPS lobes were at one point, and i assume they still are, advertised to be nicer to springs than the typical lobes.

Also, with the setup i currently have, 4.10s, P/P throttle body, full suspension, long tubes and an M6 what sort of power could be made with that setup. Guesstimates welcome.

Long story short i have a buddy with an 03 cobra that has been pullied, had a solid rear axle swapped in for the IRS and a couple other mods done (bolt-ons) and i want it to be a drivers race between the two of us. Preferably with me winning. Anyway im going to be doing heads and an intake later on down the line and i figured a cam will get me competitive much sooner.

Anyway thanks for the help

-Jon

Pretty hefty size came for stock heads there. You will choke that cams desire to breathe up top. You will probably need at least 7000 rpm shifts, where those heads will be choked, and you will be stressing your rod bolts.

The biggest cam in the books isn't needed to make good Cobra-whoopin power.

I agree the top end that i currently have is not ideal for the cam, but with doing heads and intake coming in the future i was thinking of doing this as a phase one mod so to speak.

Get it on a 234/242 111+3 if you're worried about drviability, since it'll drive slightly nicer and still make plenty of power. Not as much, mind you, but close.

And it's not a 7000RPM cam. It doesn't have a late IVC with a 234 intake lobe and 108 ICL. It just has a ton of overlap - so it'll make power and torque everywhere.

And the EPS lobes will be nice on the valvetrain. Highly recommended.

Thanks Jake, driveability is a bit of a concern, not too much of one to be honest, i was mainly looking for one Like the one you described.. power and torque everywhere nice lope in the idle fairly good street manners and good to the valvetrain so spring life wont be an issue.

What sort of fueling requirements will this cam demand?

Stock heads? Your 02 injectors will be fine.

So if i understand correctly you will start running out of injectors once you add heads and intake right?

That's right. You won't see over 430 with LS1 heads with that cam. Stock injectors are pretty much maxed out around there...
