Hi from Germany again,

Now my rebuild is coming sooner and sooner...

I want to put a new camshaft in my 1971 Cutlass Supreme 350 / 350
with 600 cfm Holley Edelbrock performer rpm, Full length Headers, with 2 1/2 costum dual exhaust, and a 2,56 rear - limited slip tag???!!!!

Parts i have already are Comp Cams Roller Tip Rocker Kit 1441 Kit
Melling HV OIL pump with a Moroso 7qrt. oil pan, and a hv waterpump
I want to build a street engine with a broad power between low - midrange (lets say a power band from about 1000 - 5500)

Now i want to put the right camshaft in it; My favorites are the CompCams
Xtreme Energy 262h with 218/224 - 262/274 - 475/480

or

Dual Energy 265 deh with 211/223 - 265/273 - 472/486

Please help me out !!!
Tell me why this not or what is better with that one =??!?
Excuse my English by the way (ill do my best:-))

Thank you very much and greetings from Germany

The dual energy will be better from 1000-2500 than the XE. The XE will be better from 2500-5000 rpm.
