318 draw through build

Hi all, Correct, all the cylinders feed the turbo. Both exhaust pipes from cylinders 3 and 5 have been opened up internally and are , when joined this way, larger than the turbo exhaust feed pipe. Notice how the turbo feed pipe is right above the collector?? That means all the gasses from the RH bank cross under the engine, run up through the LH collector , straight into the turbo pipe. The only cylinder gasses which will have to make a 90 degree turn will be cylinders 1 and 7, and that's no problem. The turbo is the biggest restriction in the exhaust system, on this project.I will be updating this project soon. I'm just a little busy with the body work that this engine is going in to.
