Ok. So I tweaked a few things, jetted the carb for altitude, timing basically went back to where I had it as that seemed to be the sweet spot that it liked.
Best run with 5600ft da was 12.52/106, so basically same run with a slightly worse da. Honestly I think the 750 just isn't enough. The thing launches good and dead hooks, 1.7 60fts but at the top of the run it doesn't nose over it just kinda stops pulling so hard. I also noticed a small oil leak from the front of the intake. So I pulled the intake to fix the gasket and decided to port match since I had it off, it was an easy 3/16 off in some ports, now the head and intake are much much closer. I do believe the next test n tune I'll try an open header/header muffler run and swap to the 850dp.
I really really want to try and get this as close to an 11 as I can at this altitude. Hopefully with the 3.55s, but I think the 3.91/4.10 swap is inevitable.
If you guys have any ideas to get this thing closer to the 11s without power adders, throw them at me.
I have also looked at the DA calculators and they say with these runs at my DA - sea level I would already be 11.60's. But since I haven't taken it down to cali test that, I'm going to take it with a grain of salt.
