Help me pick a cam

This cam works really well in a 318.

Speed Pro CS-1019R
adv. 288/298
at .050 214/224
lift .443/.465
LC 107/117
LSA 112

I have one in a 340 and the idle has a nice rumble, but not smooth. A little chop, sounds good. Idles as low as 600 RPM. It runs good in 318's too.

Comp 901 springs are about $60, retainers another $50 locks are about $10

Don't go too crazy on duration at .050. Advertised duration can be misleading. A good limit on a real streetable 318 would be around 220-225 at .050 on the intake. I'd think a XE262H would be about the limit. I tend to go a little bigger than smaller when in doubt. Any more than that and vacuum will start to suffer.
