383 / 432 Mopar stroker short block cost & build

Crane Gold roller rocker arms
I checked cam lobe lift vs valve lift with checking spring, measuring lift at the valve spring retainer with a Blue Point magnetic dial indicator.
The 1.5 Gold rocker ratio came out to 1.59, and the 1.6 Gold rocker ratio was 1.69.

The Gold rockers fit correctly on OEM replacement rocker shafts (Sealed Power) with slight deburring of the rocker shaft drilled holes, both oil and bolt holes. With the shafts held upside down I used a large drill bit to add a slight chamfer to the holes. Cylinder heads are Mopar 906 iron with 8.1 inch long ball cup oil thru pushrods from Smith Brothers; With this length there were 2 threads showing on the rocker arm adjuster between the adjuster ball and rocker arm body, and the hydraulic lifter piston was depressed .05 inch (1/2 turn on the rocker arm adjuster).
Valve springs are Comp 911-16 with 120 lb seat pressure at 1.90 installed height, and 323 lb at .540 lift. Coil bind clearance is .16 at .540 lift so no issue there.

I'm going to install the 1.6 ratio on the intake and 1.5 ratio on the exhaust. The lift at the valves will be .540 int/.508 exh. The valve spring retainer to the intake valve positive oil seal clearance is .538, so I'll pull the heads and trim the intake guides shorter by another .04 inch max so the spring retainers wont contact the oil seals. I had previously trimmed the guides 0.10 inch shorter, so just trim a little more.
The Crower cam is low rpm friendly with 267/271 seat duration and 220/223 duration at .05 lift, that with the added rocker ratio will be 226/226 at .05 lift; and .540/.508 lift at the valves. The extra valve lift is said to be good for 20+ HP on a big block. The ported heads should be able to make good use of the extra valve lift. The valve spring rate fits in the middle of Crowers mild vs race specs for .540 lift BBC cams.
If the valve action is too fast for the hydraulic lifters then I'll switch over to a solid lifter cam.
I'm not saying this is the ultimate answer, Its just an experiment...my old Ford work truck has a 428, and the RV cam thats in it has .520 lift with only 256 degrees seat duration. Its been working fine with no issues for years. Big block chevys and Fords came with 1.7/1.76 rocker arm ratios from the factory, so why not try it.
