Cheap 318 build questions

fyi here are some specs on stock HR cams available from Elgin Industries and Melling on the lift IDK 1.5 or 1.6 rockers are assumed
lift@cam duration @.004 .050 part# year
387in 253/266 184/193 MC 1309 HR 94-- (Melling)
.403ex

.398 270/259 205/196 MC1262 HR 92-93 (melling)
timing overlap
.270 276/271 197/195 15 32 32 17 62 113/113 114LCA E 1722-S HR (go figure on the lca) Elgin
(.405 with 1.5 rocker)
obviously the .398 lift 270 duration cam would be easier to regrind
take a look at slantsix64's thread for a cam card for a regrind to RT specs
318 budget build (near the bottom)
Oregon cams gives .002 and .006 data and not .004 and with the big spread between 2 and 6 lift .004 could be anywhere in between
