need the opinions of a few 340 guys

long story short, I have one heck of a nice duster sitting in the shop without an engine. I started the 340 build and quit on it to finish up my Dart race car about 2 years ago.

well, now that its done I am going back to the duster. I have kinda changed plans for the car, so a change in direction may be needed on the engine. heres what it has so far.

1968 340 thats bored .030 over
rotating assembly is balanced
Speed Pro forged flat top pistons (coated)
Hughs Whiplash cam
stock rods and stock forged crank
Comp double row timing set
Melling HV oil pump
mopar performance windage tray

thats where its at at the moment.

now the kicker. I told the machine shop that I wanted it at zero deck height. when I went to pick it all up the guy told me that the block was so far out that he really had to cut it to get the deck square. he said the pistons may be out of the hole a little. no big deal, I thought. I will just make it up on the head gasket, and I have open chamber J heads anyway. If I have to mix a little race fuel in then its fine.

I put it together and find that this baby is rocking with a set of pistons that are .021'' out of the hole!!!!!!!

I would like to keep this thing around 10.5-1 compression. I can have the pistons fly cut if I need to or use head gasket thickness.

on with the questions

I now would like to do more of a street strip build that will see 70% street. I know I need to change to a different cam. I have a set of J heads with 1.88 intake valves that I have not taken to the shop yet. I would like for the car to be streetable and run low 8's to high 7's in the eighth mile. I'm having my 727 built, and the car has a Powertrax locker with 3.91 gears.

from where the engine is at now where would you guys go with it from here and what parts/work do you think it will take for my power goals. I have a lot of experience with big block combos and stroked small blocks. not so much with stock stroke smallys.

thanks to all in advance.
