I heard that the 374 has bigger intake valves than the 320 and 352, how big are the 374 valves?

Thank you very much, MrPushbutton.

Just an FYI on this subject, I'm going to see if I can use my NOS 374 valves I bought from Joel a while back on my 327. I think the difference between the lengths can be made up rather easily with solid lifters and some sort of button or "cap" on the top of the lifter, hardened, of course. I'll keep you all updated on my blog.

Hi, Eric,

I would have thought 327" valves would be more common and less expensive than V8 valves. Let me know off list how much you want for the V8 valves. PackardV8@comcast.net

I don't want to sell the 374 valves, as they're larger than the 327 valves, and the engine I'm building is going to need them.
