230/230 is the same thing as an old school comp 280H Magnum cam, but your cam looks like it is on a 108 LSA instead of the 280H's 106 LSA. Comp's website says

"Hydraulic-Great for Street Machines. Needs stall, headers & gears. Rough idle."

Now my thinking on this is that you're sticking it in a 307. Cams act bigger in smaller engines, right? That means it will be choppier and have less "manners" in a 307.

I'm saying that the cam isn't optimally matched to your setup. When most people talk sbc cams, they refer to them by the advertised duration numbers. Yours is a 292. When I thought of a small cam for a 307, I was thinking 252. There are about 10 cam sizes in between those two.

You can put together a small inch smallblock with a biggish cam, but you need enough static compression to make power with it. You may be around 8.5:1. The more duration, generally the more CR you need. It is a 292 cam, this is what Isky says about their 292 cam...in a 350

"292 Mega Hyd.
Compression Ratio: 10-11:1
Rough Idle
RPM range:3000-7000
recomended gear ratio: 4.11/4.56
Carburetor rating: 650-780
Combination Hi-Performance Use/Bracket"

A stock cam for a 307 probably has specs something like this:

Duration @ .050" = 190°/190°
Lift @ .050" = .390"/.400"
LSA: 114


Look at this page, it calls out the specs on your erson cam...

All the sbc cams above it are smaller. I'm not telling you not to put it in, I'm saying that it isn't small.
