You know the answer.... I vote for just put it together. It will make 400+ hp if you tried not to.  How much more do you need for your streeter?

I agree , maybe not the 400 HP part , just putthe 915's on it and run it as is , nice thing is it will run on 87 octane ...

Yea I knew the answer but it was a question in my head so I had to ask. I need to get this thing off the stand and in the car before I think it to death. The bottom end will stay original I'll put a whiplash cam in it with an edelbroch torker 440 intake ( that i already have ) a Holley 800 dp carb ( that I already have ) MSD 6 AL ( that I already have ) 1-7/8 headers and swap the mechanical fan for a Taurus fan. I have a 2000 stall converter in a new trans and a 9-1/4 with 3:55 gears. Any thought on what HP the motor will make ?
What did Hughes have to say about your intake and header choice with their cam ?

When I told Hughes about the set up I planned they said it should work great, Be quick from light to light and be able to do burnouts all day long. That may have been just their sales pitch but I think I'll be happy with it. I think it's worth a shot anyway if it runs like crap I'm not out much. I really only have to buy the cam, lifters and gaskets everything else is just parts I have laying around.
Well if they said that then I guess you are good to go.

i was thinking not too fond of the intake/carb choice,but,you got the parts lying around,use 'em. it would be happier,and a broader power range with a 750 VS holley and a perfprmer RPM intake........
you are preaching to the choir , that intake is a bad choice for that engine combo but he doesn't care , so run it .

Besides I'm not going to be drag racing it
Which is why it's a poor intake choice, you can still use the carb , a dual plane would be better. If it were a street dominator then I would be all for trying it .
When you pose questions and ask for peoples opinions ... you are getting what you asked for ... if you were just looking for people to agree with what you are going to build, using what you have, then you should state that.

 Nothing wrong with the carb.It would like a dual plane a lot more though.Heck,even a used performer or CH4B would be fine for less coin than an rpm. With the torker intake it would like a vacuum secondary carb best for your application IMO.It would'nt mind the low stall as much with the vacuum carb either. But hey you have it so put it together,tune it,and get a baseline.Then see how much you can pickup by trying an intake or what ever else comes along. I built my 496 with used/leftover parts except for the pistons and I chose the wrong ones for the compression I now want.It still runs pretty well.

okie dokie. after careful inspection,making sure there is absolutely no ridge of any kind at the top of the bores, new pistons/old bore should work fine. as for running and how much HP, if your actual compression ratio comes in anywhere near 9.5 to 1, with all the parts you have stated,and sticking with only your original questions, 350 or so on a good day. should have decent torque down low,lumber/slobber it's way through the mid range,actually start moving up about 4000 rpm when it starts running out of steam,and absolutely eating gas,and spark plugs. balance won't be affected,since it won't pull hard enough on either end to have to worry about it. you asked.....................slap it together and enjoy

. Use what you have/get it running/tune/enjoy it then swap for better stuff later. Down time is 
EDIT read the OP & on balancing I would get a $10 dollar Harbor Freight gram scale & weigh the new piston/pin/ring assy & compare that # to what you get weighing a decarboned piston/pin;/ring assy you remove. It's reciprocating weight which is cut in half in the bobweight formula so it's less critical but you'll have the facts in hand & can make an informed decision and if the new is heavier you can grind the "square" on the rod small end to even it back out as the rod small end is included in the recip weight part of the formula but you'll need to rig up a fixture to hold the rod C to C horizontle while weighing the small end on the ten dollar scale. Just something to consider depending on how far you want to get into it, so much for getting up & running ASAP!
