I may have messed up here.....

I’m new on here but would value some advice from you guys.

I am in the process of gathering together parts for my 440 but I think I may have goofed in my parts choices in so far as the compression may be through the roof, and I hope you can put me right.

I have so far, a Crane 689521 cam, grind number HR-222/339, Trickflow 240 heads (78cc chambers), a set of SRP 231521 pistons that are -6cc with 1.865 compression height, bore 4.350 & stroke 4.150. Crank and rods are all Molnar items (440-4150MC6F & DH6760VTB8A respectively).

The block has not been machined yet so I dont know what effect decking etc will have on things.

How well do you think the above will work together? Someone advised that I need to ‘bleed off some compression’ with a hairier cam, but I don’t really know what that even means! I was going to use 1:5 rockers, but perhaps 1:6 would accomplish this bleed effect?

If relevant, I am going to run the 600hp Fitech on a Performer manifold (No room for anything taller).

All advice gratefully received!
