I have been away from actually working on the cars for the last few years.
Stating to gathering up parts for another 440 4.250" stroker build.
What I already have sitting in the garage:
440 Block, I think 1966 casting? And I hope the bores clean up at 4.375" (0.055 over.)
B-1 B/S heads off my old 451 stroker, rebuilt with new valves, but needing valve springs.
I have the rocker arms (1.6:1 ratio), so that will save $$$. I think I have the head studs too, or at leas a partial kit if I didn't steel some parts for other engines?
Have a Holley street dominator intake (need for hood clearance), and a bunch of carbs on the shelf, along with a new engine damper and some new Clevite coated 2.200" rod bearings (742-HNK)
What I bought so far:
A lightweight 4340 4.25" stroker crank, and 4340 7.1" I-Beam rods with arp200 bolts, and the Icon 842 (26.7 cc dish) pistons, Piston rings, and an oil filter. Compression should be around 11:1 (need to cc the heads to know for sure.).
Spent about $2,000 on the parts so far.
I didn't but a balanced kit, so will need to have the rotating assembly balanced (more $$$.)
Next to procure are main cap studs, crank and cam bearings, core plugs, oil pump, and parts not valve train related.
Haven't decided on the cam yet. This is a street engine, so something mild, maybe a solid roller around 250 duration @ 0.050, and 0.620" lift. This will decide which valve springs I get.
Recommend some valve springs. Been looking at the lighter (around 500 rate) K-1100, K-1150 springs?
I have some used PAC-1325 springs, but I think they would be overkill and stronger than needed with the cam I'm thinking of (Voodoo solid roller SKU 40230733)
