I have a 505 with a little over 10.8:1 compression in my 64, MW Victor heads with 1.6 T&D rockers, and a Bullet 640 roller. The intake is a MW Rick Allison cross ram with (2) 835 Holley carbs done by Ken Jones.
Don’t recall exact number but I believe it was around 720/730 ish hp and the same for the torque. The max hp was made at 5500 rpm on pump gas and I shift at 6k. The 64 is 3650lbs+ and runs low 10.50’s depending on traction. The 60 foots are poor and the RacePak shows a lot of wheel spin. I know it has more in it but I haven’t figured it out yet.
Just make sure you have hood clearance…… I needed to use the 5”max wedge scoop because of the raised ports.
