  1. I purchased a spare front engine harness from Jim Finn and I have mentioned it before but I finally got it threaded through the front of the engine yesterday and I did need to take the large accessory bracket off the front of the engine to do so. I also installed a new dipstick tube and stick, also from Jim, so it is pretty much ready to drop in place now. In the mean time, an observation: I copied the supercharged timing table into a chip for use in turbocharged form. Everything else on the chip is exactly the same as I had been using in turbo form. I never got around to optimizing it as I should have so before I swapped engines, I thought I would see how it performs with a stock timing table designed for a boosted engine, albeit a supercharged rather than turbocharged one. This was just for observational purposes but I quickly found it is clearly not correct for an old school turbocharged engine. The low speed performance was so soggy it feels like two cylinders are asleep. It wakes up a little bit when the manifold pressure gauge swings into positive territory, but there is definitely a difference in the needs of the two different engine styles. I know the S/C engines generally have good bottom end response vs an old school single turbocharger which needs to spool up, but this timing change cut the legs out from under the turbo response. I guess it is time to stop procrastinating and get the engine swap on my dance card.
