That may work with your heads, but i suggest upgrading your springs.

Go a cheaper route like the stage 1 tfs cam! You dont need that much lift with a stock head and the durations are small plus it is a single pattern camshaft!

What are your current mods?

With the tfs stage 1 and the right springs you wont be over what you will pay alone for that camshaft you posted.

plus a 302 low c/r wont like a 110* lobe sep most likely..... you want no less than 112-116* lobe sep.

The stage 1 is 112 i believe, if you are bent on comp cams which i also use, something like this would be more suitable pending your other mods....CCA-35-349-8

There are many things needed to make a close to spot on selection, anyone can say this one or that one, for the most part the tfs stage 1 is an all around good camshaft for mostly stock applications!

Good luck with the choice!

just a small note lobe seperation determines a number of things mostly concerning dynamic compression and on low compression engines you want a wider lobe sep to retain as much of your static compression as possible. Having a lobe sep to close on a low compression engine will cause it to be a dog down in the low rpm ranges!

These are my current mods. Edelbrock Air Gap intake (ported) with Edelbrock manual choke 600 cfm carb, ported to max e7te heads, MAC unequal shorty headers, adjuster fp, 1.7 cran cam rockers, 3:73 rear-end, full H-pipe 2.5in flowmaster, stock 5 speed.

I don't know much or at all on cams. i'm trying to learn about cams but damn its alot of factors that come into play when choosing the right one for your application. i'll stick to anything comp cams or trick flow. i don't want any b303, e303, x303 or z303 or f cams.

my next upgrade by the end of the year would be tf twisted edge heads, adj 1.6 rockers, Holley 0-76750RD 750 CFM Ultra Double Pumper Four Barrel Street/Strip Carburetor and long tubes.

Unless a letter cam just falls into your hands free dont bother! If you are pending further upgrades then save for the heads and cam at the same time! you DO NOT need a 750 on a 302 no more than a 670 at the most unless you get into a higher compression ratio etc...

a 670 street avenger works well with a dual plane intake on a 302 with 9:1 c/r.....

I don't think you have enough compression for that cam to work good.
If you do use that cam, find out from Comps what springs they want you to use if you are using a 1.7 rocker and what insta;;ed hieght they are supposed to be......
