Not surprising that much cam split did well, when you look at the flow numbers from a stock LS3 head.

I believe my Lunati cam for my 575sci is 240/[email protected] .642/.642 114ls 110icl, I havnt even fired the motor yet but I wish I would have went a little bigger and did the 4/7 swap. Also not sure about the 5* split. At this point I dont think it would be worth the investment as I dont have anything to put it in. So, with AFR325 cnc chambered, stripped 871 with whipple chiller, stock 502 bore, 8.25:1 CMI ETops...what is my safe estimated HP on 93? The problem I see is supplying enough fuel with the dump truck injection system.

4/7 swap makes the firing order the same as the LS and 8.1, it makes a few more horsepower, about 15? cant exactly remember, but I was told it has to do with crank shaft flex. All that needs to be done is swap the wires on the cap. NASCAR uses that firing order as well.
Yes, mine is standard bore 502, I would have went to a 540 if I knew my injection could supply it.

single swap, 4/7......C swap......4/7 3/2 ( double ) minimal gain maybe less than 10hp @ over 6000 revs from what I've read, I ran C-swap in my 540's, you can really hear a difference through the headers. I think the Pro stock guys started this way back in the day, it is suppose to be easier on the crank and bearing's tho.

Stock ls3 flow numbers
0.617/0.595-inch lift split, a 231/248-
if the numbers inked below are confimed correct then it does make sense with what I would consider to be a funky cam. The exhaust flows like 2/3 the intake vs more common heads 3/4 especially aftermarket. Ratio varies lift depending but in a nutshell I can see how they came up with that grind after looking at the flow numbers.

i didn't know you did that. Gotta be easier on inners but not as big of a grin on your face heading out grand haven channel. Lol... I knew the 4/7 swap tamed down and definately have a sound of their own so I can only imagine 2/3-4/7.
