5.3L to 383 stroker

[baclay9]

My block is at the machine shop getting sonic tested now. Barring anything crazy I will be punching is out to 3.905 and installing a 4" crank soon. the bottom end will all be forged. 10.8:1 compression is what the compression calculators are telling me.

I am pretty new to all this, been reading a lot over the last couple of months. Several of these have been done but it seems most step up to a 6.0 and build a 408 stroker. I am not going that route. I want something a little different and am curious just how far I can push a NA "5.3". For anyone interested here is the parts list

K1 technologies crank
Callies H-beam rods
JE 10cc dish pistons
Ported 243 heads (milled.035)
Cam will be a custom grind
TBSS intake with 54 lb injectors
92mm TB

I will eventually put a 150 shot or so on it but just going to get it running for now.

I have no idea what to expect power wise. I decided to go with the stroker to up the torque for hauling the truck around. I wil update as I go.
