My question is which ones will give me more power the Vortecs or the Sportsman II's both being 64cc.

Im comparing these two, summitracing part no.
NAL-12558060
WRL-011250-2

Thanks in advance!
I would'nt even look at a 200 cc intake volume until you think you will hit 7,500 rpm's in a 383 or 7,800 in a 350.
