hey... first post, so hey everybody, i'm johnny.

i recently had a 350 fall into my hands and i don't have very much information about it. what i do have is

350 block, bored .40+
305 hi-performance heads / 2.02 valves (exh)
flat tops
.58cc chamber

need intake, carb and cam.

right now i'm looking for the cam and i'm having a bit of trouble figuring out the right one.. i don't want anything too radical, but i want it radical enough for good street rod performance without blowing it every 6 blocks..

any suggestions?

thanks,
johnny

 

The heads will have alot to do with the cam choice - if it has 1.94/1.5" valves, then probably stick with a cam in the low 220s for duration (@.050"), around .480 lift.

If your heads have larger valves (2.02/1.6") then you can go for something around 230 deg duration, .520" lift, 110 LSA (something like the Comp Cams XE274H 230/236 cam). Check out the Comp Cams website - they seem to be pretty popular with Chev engines. I wouldn't go too far over 230 deg for a street car as it will be pretty cranky on the street.

Either way, you will get more power, and a nice choppy idle without being overly cranky on the street.

Before you choose a cam, intake and carb, I would recommend having a good look at your heads - check out the valve size and maybe have them flow tested.

A small cam with big heads won't work (lose low down power) and neither will a big cam with small heads (lose top end power).

Depending on your heads and the cam you go for an Edelbrock Performer dual plane or Performer RPM Air Gap manifold with 650 carb should do the trick.
