That Crower 60916 ([email protected] 221/229 [email protected] 455/470 LC 112) is a lot of cam for an 8:1 compression 350 engine as "QUICK-SILVER" pointed out, it probably wouldn't perform all that great in an 8:1 400 either.

A cam swap would wake it up, something like the Crower 60240 ([email protected] 210/221 [email protected] 422/446 LC 112) should be a pretty good match for a low-compression 350.

Ok so let me see if I got this right? As throttle in creases manifold vaccuum should decrease and so should the vaccuum advance right? Well if I have that right there something going on with my motor because manifold vaccuum does not decrease when throttle is applied it only goes higher! Upwards of 20"! Does this sound unusual or did I misunderstand

You're fine, and the vacuum is behaving normally. The highest vacuum will occur at higher RPM and no load.

You could install a set of Rhoads lifters to help the torque curve, but they're about the same price as a new cam. Even though I really like my Rhoads lifters, I'd opt for the cam in this case.

One thing that does get over looked when making a cam choice is how cubic inches affects the idle characteristics. What is an almost imperceptible lope in a 455, turns into a nice lopey idle in a 400, and turns into a low vacuum, finicky beast in a 350.

and the crappy thing is is this was the cam that came with the long block when i bought it! and to be honest i dont know **** about cams so i had no idea!! but live and learn ya know!
