I have been to hell and back over the fuel rail and distributor fit. The fella that fit the 8 stack had to cut and weld the fuel rails, I had a fuel leak and did not like the extra fuel lines ness to feed the rails without the cross over. I'm new to dual sync and hall effect signal and had to learn fast.
Dist. # 1 was a holly 565 101, a dual sync, but to tall. # 2, Ed at Borla told me to use MSD # 8578, nice fit but had the old signal to work with MSD box but not with Holly HP system. # 3, a holly part # 565 111 I was happy to find out that Holly just came out with this new low profile, dual sync dist. a couple of months ago but it hit the manifold half way down. I am now building my own using parts from Holly and MSD
My install is on a 427W
