Hello, I picked up a custom set of cams. Valve lift is .45 and INT is 272 and EXH is 288. Should I get springs with these or are these ok with stock springs? Mine has 52k original miles. I did buy new phaser bolts.

 

I Would Visit Various Cam Manufactures Sites and Find A Comparable Spec Cam and See What they Advise as Far as Valve Springs & Etc. Not Too Heavy Not too Light But Just Right! Lean Just a Tad Heavier If Possible! Just a Tad! I Would Not Stop at the First One You Find But Find 2 or 3 With Similar Grinds & See if They Have Same Opinion.

That was good advice, thanks! I did confirm my cams are fine on stock springs and actually had them installed yesterday evening. The sound is incredible and the whole car just vibrates at idle. Drivability is good too. My tuner, Lito, sent me an idle tune based on my cam specs as well as the other mods and it fired right up, idled great and drove pretty good. I sent my first two driving data logs and he said they looked good and asked for a third gear pull, which I'll do tomorrow. I also had a wideband installed for the datalogging. Looking froward to the next revision.
