My combo now is a 499 CI with 75 cc chambers is 12.52 to 1 compresson. The cam I am running now is a 272/275 @ .50 with .620 lift solid roller. 1050 Dominator with 5000 8" converter.
Any idea how these trick flow 270 compare to a heavily worked over stage VI?
0.620 lift is holding you back a bunch. Put some more lift in it and you might be surprised. The duration is probably roughly correct but it depends on the lobes being used. Best to have a chat with Dwayne before you start spending money. Could be as simple as picking up 50 hp by switching to a more serious camshaft.
