Engine Ideas? (sorry for posting in the wrong section)

[my72vette454]

I posted this in the engine section a while back but got no replys so sorry for posting in the wrong section but I am ready to spend money and would like some suggestions. I am building off an 83 454 block and want to come up with a nice forged reciprocating assembly that will handle 1000 hp. I am thinking about an eagle 4340 crank and rod setup with arp rod bolts and 9310 wrist pins, je forged flattop pistons with hellfire rings. I will be using open chamber oval port heads for now. Should I stay with the stock stroke or go with a stroker kit? What head gaskets are good to use and should I o ring the block? It will be turboed and will be seeing 15 lbs of boost on occasion. It will have a 4L80E trans behind it with 3.08 gears and I would like to get 20 mpg out of it cruising if possible. Will going with a stoker kit make any difference on fuel economy? I am taking the block to the machine shop monday so I need to get my parts list finalized asap.



Thanks in advance,
Mike
