I also finished setting my valves today. My cam has the 4/7 swap. But I thought when the 4/7 swap is made generally the 5/3 is swapped too. I started following the LS1 firing order but the second half of the order did not follow the LS1 order. Unless I'm crazy or I did something wrong, the cam was cut with only the 4 and 7 cylinders swapped. The 3/5 is the same as the regular Pontiac firing order??? The cam was a special custom ordered cam combination. So I sent an e-mail to the gentleman that built my motor to call the designer/grinder to get the proper firing order. We'll see what happens ther. But I'm very sure that I got the firing order figured out and all is set, ready for start up.
Update. After talking to Paul Carter, the cam was desigined with only the 7/4 swap. So I was right after going thru all the valve setting.
