318 with 360-587 1.88 heads

Well money is getting really tight and I have a fresh 30 over 318 with 360-587 1.88 heads. It has a smallish 450 lift RV cam in it. The heads are fresh with a port match job for the RPM intake. I think they may be milled a bit. I am not sure about the compression. I know this is not alot of info but I am thinking a quick cheap running 318 with a bit of power. I think the pistons are speed pro. I have all the parts to make a complete motor and I know this 318 is a good runner.

What do you think HP wise I could get out of it with a small cam upgrade maybe a 484 cam or what cam would you recommend? and a Eddy RPM intake and PRW rockers with Dougs headers and I have a 750 speed demon carb.

I am thinking about selling my 402 stroker with RHS heads to fund Mortage and bills and build this 318 for a temp motor. I know I am going to regret it but I may have to do what I have to do.

Advise? Sell the wife? Sell The dog? Sell my Dirt bike? I have to keep the kid.
