Re: Cooling down a 350: heads/cam, just for kicks
I don't believe the 461's have accessory holes. However, I googled around a bit more and found some other discussion of small-valve heads potentially allowing equal or better low-end than the "benchmark" 1.94's. Also, the 461's are going to net no less than 10.5:1 compression with the pistons present, and I need it to be a mid-grade friendly engine. Supposedly the 68cc chambers of my 327 heads would put compression at 9.5 which which shouldn't require premium.
So duration is what causes rough idle? I thought it was lift... but that's why I'm asking.
