    Well after a LONG wait and numerous phone calls to get things lined out and the shop that I bought all my parts from spending hours on the phone figuring all the stuff out its finally here. I ended up with a 4.1" stroke crank cause well EVERYONE that strokes motor makes a 408 and damnit I want something different. So I ended up with a longer stroke crank JE SRP forged pistons, forged rods and of course a forged crank. I finally got another camera to take pics of my stuff with instead of my damn camera phone Its kind of dark cause the lighting sucks and I havent had time to figure out all the settings on the camera.
    my feet and the crank box

    the crank shitty pic

    side view of the crank

    the rod

    side view of it

    If there are nay other pics someone wants let me know Ill post them up tomorrow.

    Parts are at the machine shop so hopefully I will have it back by the end of next week then get my fat turd in the LOW 11s on a 250 shot. Built 80e here I come LOL.

    Allen I hope the retune you sent me works

    I think its time for me to get HPT to start laerning how tune myself especially since an 88mm turbo is its future by the end of the summer

    No, the max bore on a 5.3 block is 3.89. That will give you a 346 though. Even at 3.89, you have to have it sonic checked.

    As I see in your sig, Dart heads come with lil chambers. May want to reconsider...

    Aside from that, looks to be a good setup.

    Its designed around those small cc they will be cut for the bore. I went with a small combustion chamber head so later on I can put 72cc heads on there for the turbo this summer

    TRT my 5.3 I checked it and it can bored to 4" with plenty of meat left over so it can be bored.

    Huntin for low 11s on a 250 shot with a 3200 stall and an 80e

    More pics will come when I get the block back next week.
