Rocker ratio is 1.6. You can get all that stuff here: http://www.3800performance.com
You can get springs almost anywhere. I am using compcam LS1 springs. The rocker arms you will have to find some that are offset. So they will be more expensive. Do you plan on changing the ratio? -
Thanks for the link. I am looking for something to give me more intake and exhaust lift.Other than a cam, with a cam you sould have computer programming right?2000 Navy Blue Firebird <br />3.8 A4 Y87<br />Member of the MTFBA (Middle Tennessee F-Body Association)<br />Factory dual exhaust,Pontiac Decal on w/s Cutout,A/F Ratio & FP guages<br />K&N Filter Taylor Spiro-Pro plug wires and NGK TR6\'s<br />Whisper lid,NX Wet 50 shot<br />Hotchkis LCA\'s & Panhard,Michelin Pilot XGT Z4 245/50ZR16<br />SLP Strut Tower Brace<br />NA 1/4-15.132@89.29 2.194 60\'<br />N20 1/4-14.174@98.04 2.228 60\'<br />F-Body Gathering 5 Trophy WinnerComment

Not always. Sometimes you can get away with it. If its a mild cam I think you would be ok. We are still experimenting with different cams. Yea check that link they will have rockers that will work on our cars with 1.9 Ratio.Comment

Just got off the phone with compcams again. They said right now the cores are on backorder. He said the cores were supposed to be in on the 27th. Today is the 30th and they are not in yet. So it is possible these cores could be in any day. But you might be waiting a while.Comment
