Small Block Cam

[Wbulk]

I built my 302 when I thought I was going to have to pass emissions. They have since changed the law for classic cars so it is no longer an issue. I am now reevaluating my cam choice (Comp HE 260H) as to conservative without needing to pass emissions test. I have a 71 302 , 9:1 CR, stock heads with mild porting with exhaust smog hump removed, Edelbrock dual plane, T-5 Trans, 3.50 rear gears. I don’t want to change the heads.

This is a street car, not a race car. I am looking for a cam that will give me a little over 5,000 rpms and 270 to 290 hp. I plan on setting the rev limiter at about 5,300 rpms. Most of the driving will be between 1800- 4,000 rpms. I have read a few articles where this is doable. I have been evaluating the following cams and am asking if anyone has experience with these.

Comp HE 268H @ .050 218-218 dur., Lift is .456/456, LC is 110

Comp XE 256 H @ .050 212-218 dur., Lift is .477 and .484, LC is 110

Edelbrock 2122 @ .050 204-214 dur., Lift is .448 and .472, LC is 112
This cam is advertised to rev to 5,500 and seems to be a very popular street cam, as many other brands have copied it exactly.

Opinions and advice would be appreciated.
