Two of the cylinders fire so close together that one of them is prone to run lean. Not a good thing for blower motors. The mechanic that rebuilt my engines recommened that I let him do this.

[QUOTE=Quiet Storm;2334853]I had mine rebuilt and loved the outcome. Bored them out to 509 blocks. Went with a hydraulic cam and Morel hydraulic lifters. Changed the fireing order. Reworked the heads. Went with MSD ignition. Arizona Speed reprogramed the ECM's. The Blower Shop rebuilt the blowers. They can make the blowers stronger but I wouldn't run them for much more than 200 hours before rebuilding, depending on how you drive it. I picked up 150 hp without intercoolers. I could have got more hp out of them with the intercoolers but wanted reliability.
If you look up 10X he can tell you more about them. He helped rebuild them.[/
What was the firing order and what did you change it too. ?

1-8-4-3-6-5-7-2 is a standard Chevy firing order.
