Good job on those valve covers, they turned out real nice.

JB Weld is amazing stuff, I have fixed a number of dirt bike cases in the past with it and they always held up very well.

Re: My turbo 4.8l 87 IROC build

keep it aluminum. and look to see if you can find an ls6 cam or something man, those 4.8's don't like to go over about 5500rpm before they fall flat, and that turbo is going to want to live around 6800 or higher.

Install the engine/trans without shifter and tape covering the hole. Mark the 4 corners with a sharpie. Drill and use cutoff wheel to connect the 4 corners
