Cam lope

You won't ever be able to get the "lope" out of twin cam that you did from an evo or shovel.. Idle needs to be 950+ to get proper oil flow.. The SE211 cam has a very distinct lope even at the 950+ idle but it's not a torque monster cam.. Still it's a lot of fun but needs a CR of 10.25 or better to realize it's performance potential..

I think Darktrak is looking for a performance cam with a choppy hot rod lope, not a potato-potato idle; somthing like this:

The factory recommended rpm settings is also to keep charging the battery at idle.

By a shovel. You'll never get it out of a twinkie. The oil flow prob can be solved w/a new oil pump. Then you can decrease engine speed at idle w/ whatever the hell you computer nerds are talking about. Also for a radical cam you'll need new springs and valve reliefed pistons. THat will get you close. Also a carb conversion will help, give her just enough fuel to spark it.

I dont really want that "old shovel plopping along at 500rpm" sound. Just some more staggered exhaust notes...It's do-able, i have faith in that for sure. Just gotta find the right cam. On a seperate note, you dont have a video of your train idling with your flappers do you?

I know; the other vids are duals and you won't get that sharp snap pulse from duals that you will get from a 2:1 pipe. Vid #3 is a stock 96" with SE204 cams. The 204 cams have an intake close at 34* with an 8* ground in advance which increases corrected compression and gives the exhaust note that sharp bite. You won't find many other cams that will idle like the 204.
