HP#'s??
In every test that I have made with the 561's they performed worse than the other castings. Every set of 561's that I have flowed were not as good as the earlier heads by a large margin. Maybe there are some good 561's out there. I've just never seen a set!
thats interesting. i wonder were the other thread got its info. is it possible the non 561's you tested were ported and 561's were unported?
(I run Stock Eliminator which requires unported heads)
i hope it didn't come across as i was argueing with you i just ask questions so i could learn from you guys im only 20 so i have very limited knowledge when it comes to these cars.
I didn't take it that way at all. I had read the same thing about the 561's, fixed a set for my Stocker, and slowed it down. That is really what got me flowing the virgin castings. Maybe there are some good 561's out there. If so, I would love to hear about them.
