yeah I always liked the 35R but the guy who will be doing the install said to go with the 63 with the "S" housing so that's what I bought. As far as the rods go I have no Idea if I have the 900hp or the 600hp rods I just told him how much power I wanted and he said he can get eagle rods for 500 so I just gave him the money. I have never seen a part number for anything for the block I just give the money and say get it done. so all in all the pistons and rods ran me 1200 and the sleeves cost me another 500 and the labor was a G. It's not a street car It will just see the street when I see trailer queens out on the prowl. Anyway am having a real hard time finding a manifold for the h22 I mean I can find manifolds but none supports the 48mm pro gate that I have and that sucks. Where should I look and what quality parts do you recomend I get that i dont have already?Thanks for the info guys/gals.
