My 340/420 Stroker Build

I don’t think the 260/264 is on the large side at all. Ideally, because mine sees usually a good bit of track time, something 266-268@50 would be closer. Again I ran this cam on a stock stroke 10 to 1 360 previously, and drove it everywhere.
Howards makes all the cams for Hughes. Be careful, some of those lobes, especially the 904 ones, are very aggressive.
I like the cams Howard’s sells better for what you are looking to do.
As a couple of guys have mentioned, big stroke eats up duration.
Buddy of mine who bought my old stock stroke 360 is putting I think it’s a 246/250 solid in the 360. It’s a Howard’s. Again, stock stroke. He intends to drive it 15 miles each way to work in good weather.
I like the lifters with the oil hole in the face, worth the extra, they sell them.
