as my son and I close in on his gtx clone, we have had his motor running, but will be improving his upper valve train with roller rockers. also gonna swap out his ignition with msd 6al box, and a 8546 dist. wondering which springs and spacers to start with. I think his specs are as follows. 477 stroker, iron heads 11.5 to 1 ross flat top pistons, comp cam .545 lift, dur 241 247. dual quad with 2 750 afbs on a stock cast iron manifold. hemi 4 speed, mini tub, 410 dana. thanks....bob and kevin
