I had my mind set on the hughes solid flat 268/272@50-.650 cam for my new 511 build, which will look something like this. 511,victor heads cnc'd by hughes flow 359@.600 and up, 332 port window, 11.5:1, 3350# weight, 8" vert, 727, 28" tire, currently a 4.30 but i have a 4.10 i can throw back in. This will use a 1100 dom as well.
Now i'm also looking at a solid roller of 276/281@50-.680/.660 on 108.
Performance wise what are the pros and cons of these two cams in this 511? Hughes used to advertise there solid flat cams as equal performance to a solid roller if using a 1.6 rocker arm on their solid flat cams. Not sure i can believe that, but i'm just looking for some input on this subject. This combo will be a street/strip deal or a street car i can race. Might see the track once per season. I guess what i'm asking is would this be a good pick if i go roller? Thanks
