I heard about your 67 gto death grip ride. Bad azz from what I heard. What ratio rockers you running. I may have missed in OP.
Dennis r built and just sold a while back some stroked ls3 with ls3 cnc ported heads and made like 650 hp at 6,500. Ck out his build sheet. Ran them in a 32 sunsation 88 mph.

Your killing me Smalls. Lol. Ordered 237/237 114.5+3.5 .621/.612. Very broad power but will loose my past peak power without exhaust split which is not a concern. I build my cam totally off of events. Not @.050 or adv numbers. Concern with this cam is planing as the daytona is very tricky to push over and low end will indeed suffer. Counting on the dual plane to do its job there. Will have great power from 3500-6200 though. We will still be utilizing the original cam on the Dominator which is a 6.0 ls3 heads.

marine motors like some split in the camshaft,even the car guys w/ good headers run split.just remember to turn up that correction factor knob on the dyno.

Keep up the good work and keep us posted regardless. Hey worse case scenario you don't achieve your goals but you certainly don't reach them by couch sitting just thinking about it. Your going after it. Would be great if you could try a couple different cams on the dyno and share your results. That's kind of the backbone of this site and much appreciated by most. Also do a search on even split cams here. There was a thread on it a fews ago if I recall. The last custom grinds I bought had only a 4 deg split and made great power once I got the valvetrain stable. The last even split cam I ran was in a 383. Never forget comp labeled it as king of the drive in cam and that it was. 292 magnum cam.
I ran that with GM worked over camel back heads (closed chamber) with a non superior exhaust port. Was a crap shoot at the time being only 18 but made excellent power.

I respectfully disagree. The events justify the cam. Mainly ivc and evo. The ivc determines peak. The evo determines where the powerband is located. The split determines how well it holds power past peak but also softens low and mid power creates unneeded overlap on in my case a rather lazy intake port. Low initial velocity creates intake reversion due to overlap. So one this particular head I do want less split which is clearly justified. Ill post a pic of the cam card when they arrive so you know my upcoming dyno sheets are not bs. Ill also post the baro. Humidity. Temp and correction factor being used. Wherever it ends up hp wise is where it is. But the numbers will be real and a good aid for future builds. Again the pount of this thread.

Dennis r built and just sold a while back some stroked ls3 with ls3 cnc ported heads and made like 650 hp at 6,500. Ck out his build sheet. Ran them in a 32 sunsation 88 mph.

I bought them from Dennis. 416CI, 651HP @6500, 563Tq @5000. They're beautiful. Going in a Sutphen 30 Ocean Pacer this summer.
