i picked up an ultradyne cam for my 350 chevy build-up. specs: 217deg/454lift/112lda (basically comp cams 268h). ultradyne claims its powerband is idle-5500. isky has a slightly smaller grind (214/450/108) and claim a 2000-5800 rpm range. so, first off, what would y'all say the rpm range is?

secondly, which intake best suits this cam? basically, would an intake which pulls higher than 5500 or so be of any benefit? will a Street Dominator pull any harder down low than a Performer? also, can anybody tell me anything about holley #300-28z?
thanks

rpm range is where the cam is intended to make its power-your cam is made to make power from ide to 5000rpm thus you need a dual plane intack(usually)(which also makes power in that rpm range)the key is to get your parts to match at the same rpm-thus it will be fruitless to set up your intack and the rest of your motor for over 5000rpm if your cam is made to only work from idle untill 5grand. warning-mix matching parts to hep other parts, power drop offs, is a bad idea.and for questions on witch intack to use start buy calling jegs or summit-they will lead you in he right direction "if it ant fast it aint good"

As for cam rpm range I think from company to company they rate um differant.I think some rate um by redline some by peak power.I have a cam thats rated for 2000-4800 yet edelbrock sell the next step down claiming idle-5500.Also could depend on what heads they used on there test engine.
As for intake a Performer would be best for your set up,an RPM would make more peak power at the expence of a little low end.
