Re: 289 with 351w firing order
If you can get a flathead firing order camshaft, that's the best. 2/8 swap. 15486372.
Kaase uses it on a lot of big blocks, but I don't know of anyone using it on SBF. IIRC, it's the similar to an LS-1 firing order just numbered differently.
I asked Scott about it when I had my last cam ground, but he said its a waste. Looks to me like that particular order would work very well, however I am not THAT deep into firing order changes and their affect on crankshaft harmonics, intake pulse tuning and exhaust pulse tuning. I wish I knew a way to try it without having to spend $750 on a custom core camshaft for my 438".
