It's alive!!!!!!
Cam break in, and then about 40 minutes later. Pulling good vacuum. This cam and refreshed heads have woke up this engine. It idles really smooth and pulls up past 5,000 rpms with ease, whereas, before it sounded like it struggled. It may have been starving for fuel though. The PO said it was a 283, perhaps he was told that, or he was just trying to make it sound more authentic to sell it, but he had a fuel pump for a 283 on it. I replaced it with a 350 fuel pump and that may have contributed to the increased power, along with the cam upgrade. I have a tiny fuel leak at the fuel pump to fix, small like a vapor, but since I need to fix that I'm going to replace one more fuel hose while I'm at it, the one from the tank to the steel line on the frame. Replaced the others with the multi-fuel fuel injection hose and it is much higher quality than even J30r7 hose. I need to clean the cooling system because these heads released a bunch of rust debris into the system. Will be driving it tomorrow. And I decided to take it on my upcoming trip, too. Figured why do all this work just to have it sit at home when it can enjoy some scenery with me.
