Default finally done, still needs another dyno day

Finally got my car on a Dyno Monday after a long and stressful year. Its still has a ways to go to be finished but here it is. lq9 w 317s, ebay gt42, ls6 intake, 80lb injectors, 340 in tank pump, th400, 3400 stall, and a Jeff Lowry cam. Right now its tuned at 9 lbs on pump gas and waiting to dyno it again and turn it up,but first have to make sure its not hurt. little bit of metal in the first oil change has me on the rag..... BUT its my fault since I didnt wash my heads down after they came off a engine failure w a spun bearing and going to hope its from them and not a engine failure. oil pressure is still a solid 40 hot idle and 66+ up in the rpm's. I was stupid, didnt think and in a rush.... next step if after a few more oil changes the metal disapears (have been told that metal in a new engine is common during break in) its back to figure out the flat spot from 5500-7000rpm
A really big thank you to my cousin Kevin who helped out a lot

put a bigger turbo on it. I bet it has close to 4:1 back pressure. a pt88 is a bit smallish on a 364ci engine.

I will be going bigger in the spring when. Can afford the turbo and to build another hotside. I will be going s475 w the 96mm turbine 1.32 t6 housing. For now its a budget build to learn and get my feet wet.

Thank you. This started as a gt45 but a unfortunate misshapen occurred so when I went to buy another I got a good deal n the 42 and figured I would try it. It was identical to the 45 but larger compressor. I drive my car a lot so I wanted somewhat driver friendly and wasn't chasing any up numbers.
