Hey guys, noob here, possibly pickin up a 67 convertible GTO clone tomorrow w/ the 400, curious to know what oil weight would be recommended. I read over at the BITOG (bob is the oil guy) forums that a 10w-40 or 15w-40 would be ideal for this engine. Sound about right? Thanks in advance for your help. :cool

those are probably fine. I have been using Castrol GTX 10w-30 for 2 years. I change the oil every spring. Cars get driven in March - November.

Awesome, thank you for your replies! I ended up not gettin the one with the 400, way too many problems for the money they were asking. gonna check out another one today with the 326.
