motor blew, help with decision i have a 01 ta 6 speed. i recently blew it up i think?? smokes like crazy at high rpms and scan tool says cylinder 7 missfire, i put new plugs in to have them fool out with oil all over them. i have been looking for a replacement, everything from a used one on ebay?? ( hard to trust that thought) to sending mine off for a rebuild. i also have been looking at the zl-402 short block. also my local machine shop tells me that they can bore it out, so i can rebuild it from there. But like everyone else i am looking for the most bang for my buck. hey its the american way lol. so any suggestions would be very helpfull. also i have some rods nocking so would it be a good idea to get them ported to ls6 specs. and rebuild them or buy a set? i was looking at the patriot heads they seem to be affordible, i have a budget of $4000.00 and under. help please i want to get all i can with the little cash i have to spend. thanks....... oh yea one last question if i get my local machine shop to bore and hone it can i make it a 383 with the stock crank?? also if the sleeves are not in to bad of shape can they reuse them or will i have to get it resleeved to? i dont wont to get ripped of>>>>> thanks

i pulled the v. cover ans checked the push rods, they are in goood shape. A couple of things i did notice though. the driver side back exhaust port, there is oil comeing and leaking out of my headers ( loose header bolt .... fixed). also, my oil pressure has droped, holding around 40, and a little below.
sounds like the shortblock is done.. I bet you pull the heads and #7 has big area of missing ringland.. ask me how I know LOL.
if the cylinders aren't too scored up and you don't need teh car immediately, I'd think about pulling the motor and having it rebuilt, maybe go to a 383 stroker setup. If you rebuild it and reuse your stock crank, just put in all new bearings, new pistons and rods, that would be your cheapest bet. A new oil pump, that sort of stuff shoudl be done at the same time while it is apart too... stud the whole motor, maybe make a cam change, check the lifters,etc.etc.
If you pull the motor and bring it somewhere to be rebuilt, then reinstall it yourself you might be able to pull that off for 4000... but this type of thign can get expensive in ways you can't imagine... again ask me how I know.
