Horsepower guesstimation?

I have a 318 that's .030 over with similar spec's and my dyno (the dragstrip) says about 210hp.
First if that's a small block 727 I would sell it and use the money to buy an eight and a quarter rear end. Reason being is because any small block you put together your 904 transmission will be able to be built to handle it at much less weight. No real funs going to happen until you change those gears with that 318. I like the 355 for what you're talking about and definitely an 8 and a quarter if you just staying with the 318 for a while much more budget-minded. I do believe I had about $300 in my 8 1/4 with a 355 trac-lok. Like I did this will be easily sold one day when you decide to go crazy and start getting big huge horsepower. And at that point just skip right by the eight and three quarter and go to the Dana 60.
