I just talked to the only two manufacturers I've had any dealings with, and wasn't in love with either suggestion.
Last year I ran a 286/297 .799/.768, 111 LSA, installed at 108. I'm sure this is way wrong and probably why I ran out of steam when I started upping the jets.
So, hoping to get a new bumpstick to allow for the second gun, the first recommendation was 285/302, .846/.820. Thinking thats too short on exhaust duration, and more lift than I wanted to run.
Second stick was called out at 287/306, .846/.820. I like these duration numbers, but still more lift than what I wanted.
Both are on a 116.
I've been running a pretty weak spring with stainless steel valves and stock size lifters and getting away with it. I was hoping to just up the duration and widen the lsa, but apparently nobody has those lobes.
SO, whats out there for a 565 thats getting hit in the 250-550 range???
