514 build-- need some help
For those of you that have built a 514 I would like to build a streetable one for my 78 f250 and I was wondering about what cams work good, rockers, My rotating assembly is roughly 9.5:1 compression and it will be going in front of a c6 and has a 2200 stall converter. I have L&L headers, performer rpm intake, and d3 heads.
My heads are rebuilt with 2.19" intakes, ported out exhaust, and machined for stud mount rockers. My goal is strong power up to about 6500 rpm. Is this doable, I was looking at some aluminum heads as well and sell the 2 sets of D3s I would end up with. Would aluminum heads make enough difference or are they just shiny and expensive?
my engine building experience is limited so I was not sure what cam specs to look for and what rocker arms and pushrods would work well with my iron heads and what would be effected by going to aluminum heads. Thanks any help would be appreciated.

Solid or hydro cam ? roller cam ? " My rotating assembly is roughly 9.5:1 compression " was that figured with the D3's at 95cc ? How far are the pistons in the hole ? what pistons ? Push rods length has to be figured out and depending on the cam you might want to move up to 3/8" rods.

thanks for the reply I have a set of 3/8 push rods and I want to use a hyd. cam. The compression is ~ 9.5:1 with d3 heads. I am buying the rotating assembly already assembled in a block and it has a set of refurbished d3 heads with it with 2.19" intakes but no porting and no milling. I have a set of d3s that have 2.19 intakes, machined for stud mount rockers, milled 0.010 and ported out. I am not sure if the push rods will be right since I plan on a bigger cam in this build but I will play that by ear. Well, I have the ball rolling thanks for the help this far.
