Found a nice cam option for the L31
So I just noticed a nice little cam option for a L31 or even L30 Vortec. It is a GM performance parts steel billet roller cam. Comes in the newly introduced GM SPO 350 /357 HP crate engine. Basically GM took the old 330 HP 350 HO and set it up with a roller cam rather than a flat tappet cam. It is 215/223 @ .050 and .473/.473" lift. GM is using production Vortec heads on it down to the same springs, retainers and seals that the L31 used. Basically a little tamer than the LT4 Hotcam and drops into the stock engine with no head mods.
GM Part Number 12677151
Just picked one up for $287. I am going to run mine with 1.6 rockers and LS6 springs.
Power rating for the crate engine is 357 HP @ 5,500 and 407 TQ at 4,000. Running GMs low rise dual plane intake from the 330 HP 350 HO, 600cfm carb, HEI set for 32° total advance and headers. The 330 HP engine was known to make more power than it was rated and I have a feeling this 357 HP version may do the same once people start testing it.

The engine was introduced @ SEMA 2016. It is not "new" by any means.

Go farm you're old SBC BS somewhere else.
