Just to add to the list of things to do, I went and picked up an 04 LQ4 today :rofl: 37,xxx for $400. One piston is bad, so I'm debating to either just replace the one piston or go with .030 pistons and make it a 370.
Plans are almost a full rebuild, cam, TBSS intake, bigger tb, long tubes, port the 317s and maybe have them milled a tiny amount, springs, pushrods, lifters, rockers, trays, oil pump, water pump, and all the other little misc goodies that add up to a shit ton of money.
You can see the bad piston here and some slight scoring on the wall of the cylinder.
Probably shoot to have it done by next summer if funds allow. I've been looking up stuff on Texas speed and summit, it adds up quick that's for sure!
