318 build need ideas first build

Trying to edit a post on my phone sucks so I'll just add it here.

You are going to also want to determine how comfortable you are with what RPM range, that will help you pick your gearing. Here is a useful tool.

I managed to kill a 2.76 7 1/4 pegleg in about one year with the following minor things.
68 318 stock bore, (I have not checked compression due to general laziness)
Lunati Voodoo 10200701 cam.
Edelbrock performer.
600cfm cheapie summit carb.
New timing chain.
New spark plugs.
Original exhaust manifolds and single pipe.
Original 675 heads.
Crappy old points that I have been too lazy to replace but need it.

I did not beat on the car, and that 'wimpy little 318' still killed that rear end.

Would I go with that cam again? No, I would probably get the 703, but that is because I am getting 4.10 gears on my new diff, and have plans for an Offenhauser dual intake/carbs setup. Will it work as good as an RPM AirGap? I dunno, but I want to try it. I have a set of 302 heads in my closet sitting next to some Doug's D453 headers. Will I hit 300-350 rwhp? I do not know, but this is fun, and a hobby that lets me spend time with my 5 year old son. Will my 318 be the fastest car around? Not by a long shot, it will be quick though once I get the suspension tuned.
