stock L67 3800 SC out of a 2000 buick regal. Xp cam, ported heads, ported LIM, Gen V SC, 2.7 pulley (stock pulley is a 3.8), Northstar TB, headers, 2" ZZP intercooler, E85, stock 4t65 non HD trans, 2500 stall, 60 lb injectors, walbro 255 fuel pump. I think that's about it.
Nothing really power wise. I'm pretty much maxed out at what I have now without spending a shit ton of money on other junk. May go turbo in a few years if I get bored with it but then the trans will grenade on the first pass so I'll pass on that.
Next big step is to add A/C back to it and eventually cruise and just make it a fun cruising car.
