[QUOTE="Bad Company, post: 15898013, member: 141815"] LOL....If I would have realized you were comparing Mark's engine to mine I would have been able to give you a better idea of the differences. Yes, my current cylinder heads flow numbers exceed that engine combo by a good margin. At this point I don't know how high the boost would go with a smaller pulley. Because of the mods done the combo may not build boost as quickly with what would be a standard pulley change for an engine without those mods. Meaning a 1/8" smaller upper pulley may only give me a 1/2 psi boost increase, whereas in a different engine that same pulley size change may increase boost by 1 1/2 psi. If I remember correctly at that time Mark was running the same piston CR as I am now. The short blocks I believe are almost identical in your comparison, whereas my heads and intake manifold have quite a bit more work invested in them by Tony. I also have more mods in the exhaust system to lower restrictions then that car had at that time. Bill felt with more RPM and boost that I'd smash through 1300 on his dyno very quickly. Before each pull he's give me an estimate of Hp output that he felt the car would produce with the tune he wrote. And each time the car responded by going quite a bit higher then he expected the results to be. When it laid down the 1100+ he said if Tony says it can do 7500 with no issues that Tony could get in the seat himself to mash the loud pedal. He said he was done and that he felt that there was no need to change pulleys or increase RPM for a number .......I agreed, because it exceeded what I was looking for with ease. [/QUOTE]
