The pics in this thread describe what I was trying to tell you.

blackss, so what was your decision for a rebuild, did you go stroker kit, or forged bottom end, or just stock rebuild?. anyone know off hane what a stock crank kit costs? then i'd get good bearings. or is that just a waste of my time and i should just get a forged kit and do it right the first time and only once. thats how i am with my stuff, i dont want to take this motor out again next year.

i thought for sure the 10 bolt was going to explode before this happened, now ill build the motor and the first time i drive it, the rear will probably go kaboom, just my luck. might as well sell the drag wheels to fix the motor.

Machine shop had an LQ4 shortblock that the machine shop owner was gonna use for a project, but that project never got started. He sold it to me for $300. It was disassembled, so I bought new bearings and piston rings from him, and had him hone the rod ends for my ARP bolts. Was out the door for like $530 and assembled it myself.

Here's the thread to my whole debacle, from when I blew the stock engine to the bad shortblock i bought to the lq4 build.

so financially I don't think i will be able to build a 383 right now, so it looks like the engine will come out and all new bearings installed. new main caps, and arp bolts. I will get clevite bearings and then the car should be back on the road and good to go for a long time seeing it only makes it to the track 2-3 times a year and only driven about 2500-3000 miles a year.

I love the tusnami cam, sounds awesome and drives very well. now that the motor is coming out, I may have to do a custom cam to get the most out of my heads now. so all the followers of this thread, someone may be able to own a 1000 mile next to new tsunami.
