Sp2p Intake which cam to use?

I've just won a Sp2p Edelbrock intake and would like to know if a Dual energy 255 style cam would work great with a stock 400

Sure will...a lot of guys around here will recommend that cam for a basically stock 400, along with an XE256.

Do you have to worry about guide plates with this cam?

not guide plates, but springs, although I suggest changing your springs to ones that match your cam, stock springs will maybe hold.... and if your engine has exhaust rotators you should change them to guide plates...

I hope that cam is small enough not to have a lope. Those intakes were designed for stock engines. Do NOT raise compression with a SP2P intake above stock, The dynamic compression can get very high. It the only thing thats worse than useing a large cam with it.

the intake has nothing to do with your dcr, that itake works grate with rv cams, the down side to it its that it aint worth for alot of rpm....

You don't think the intake can have a tuning effect of cylinder pressure?
Intake manifolds have almost as much influnce as camshafts do over what RPM the engine will work best in.

Not realy in cylinder preasure, but it will affect in port velocity, cyllinder preasure is only afected by the event of openning and closing valves, the charge or mixture will be afected by port velocity thus afecting power at low rpm, this itake has small intake runners which will increase port velocity, thus will increase low end torque and throttle response... I know for a fact that it has nothing to do with dcr....

S - small, P - port, 2 - dual, P - plane. Small port dual plane manifold for low and mid range
