Which Camshaft ?
Hi there ,
Looking at doing some mods in the future , currently running a 1987 350 TPI in my 1986 auto Z28 (Factory auto 305), I would like to fit an aftermarket camshaft thats going to make it a little more perky and above all that nice lumpy Idle .
I would like some info on what make / profile cams I should be looking at and if anyone would like to share there stories.
Also where does one look on both motor and trans to identify exactly what I'm running as car is not all original.
Thanks in advance

I used this utility when deciding which parts to buy for my engine.
CamQuest ? Select The Perfect Camshaft & Valve Train Components
I've got this cam, if I recall correctly.
