Hey guys, quick question: What's yall's opinons as far as cams go for a 289 w/ following mods: port/polish heads, .030 over, forged pistons, roller tip rockers, 2200 or 2500 stall in near future, performer rpm intake, around 10:1 comp. I dont want too much lope, but enough where it makes me smile when im sittin at the light next to some ricer. Any help would be appreciated as i know nothing about choosing a cam. Thanks -Ryan

lift 474 intake-494 exhaust and duration in the 280-290 range. Keep duartion at .050 to about 220 degrees.

Dual pattern, under .500" gross lift and under 215 degrees @ .050" lifter rise.

See a comprehensive list here

Look at the SVO A312 down the page a bit...that's what I'd recommend..

I guess another question i might ask is what exactly does each number mean and what effect does it have? Thanks guys

Ryan,

The "lift" refers to the distance off the valve seat that the valve opened at the full open position.

"Duration" is the amount of cam rotation in degrees that the valve is open. The industry standard is to consider "open" as .050" of lift or more.

Install the 3.55 gear with the converter and the cam everyone is talking about and you will have some fun. I love mine.

By the way, Edelbrock recommends #5722 valve springs (110# seat pressure) and screwed in rocker studs.

The .472/.496 cam is part of their Torker II package, but it works great with either a Performer or Performer RPM intake

Great cam comparison chart.

Great cam comparison chart.

hehehe...amazing what a minute on Google can turn up...I typed in SVO A312 for that one and Cam Theory for the link further down this thread.

Now, how to teach net newbies to search on their own?? *G*

Give Comp Cams a call. Tell them what you want and what you have. They can tell you the best cam to run.
