Hello.

Been browsing through the forums and noticed some guys running higher timing on Vortec headed engines than I thought was normal. My setup feels kind of flat. I’m currently at 15 degrees base with 28 degrees at WOT all in by 3000rpm and 32 degrees at cruise. Before I had WOT at 32 and cruise at 36. Either way, it feels a bit flat. I tried clicking links to a few tables, but they were dead.

My my setup is as follows:

I own a K30 square body. I recently installed a new L31-R Vortec 350. It has a Weiand street warrior intake with a Holley sniper. The sniper controls my timing with a Holley dual sync distributor, msd blaster ss coil and msd 6efi cdi box. Exhaust is a pair of hedman black maxx ceramic truck headers, 2-1/2” pipes, h-pipe and dual borla proXS mufflers. Trans is a th400 with a Hughes xtm converter and 3.73 gears with metric 33” tires.

i have a steady idle, pulls decent vacuum (~30kpa at 750 rpm idle) and it starts easily. Throttle stabs in neutral are without hesitation and it revs freely.

What would y’all recommend?

Thanks in advance!
