Here's my SCJ headed 521 build...
D0VE-A 4-bolt main SCJ block bored and honed to 4.397
4.300" Scat Forged crank...
Main clearances are .0027 and rod clearances are .0023
6.800" Eagle H-Beam rods...
Kaase rear sump pump...
Probe flat top pistons...
Total Seal file fit rings gapped to .028 Top, .032 2nd, and std. tension oil ring...
FRPP SCJ heads ported/flowed by someone in Michigan to 385/254... Decked to 71cc for 14.2 C/R... (according to Diamond's website calculator)
Fel-Pro 1018 Head Gaskets...
Springs unknown, but 308# seat & 805# open, with Titanium retainers and lash caps... Std. 2.20/1.76 valves...
FRPP timing set...
Solid Roller spec'd by Tom Magyar at Ford Performance .280/.288 @ .050 & 786/726 lift @ 113 lobe sep... Installed 3.5* adv... Piston/Valve clearance is "tight" (Huh Blake...? ) Ground & dbl. pinned through Scott @ RHP
Scorpion 1.73 Roller rockers...
Untouched 4500 Victor intake w/ 2" open spacer... Quick Fuel QFX 1250
No dyno #'s, but my truck weighs 3220# with me in it, and has a best ET of 6.17 @ 112 mph 1/8, and 9.73 @ 136 mph 1/4 (@ 1200') and 6.34 @ 112 mph 1/8 @ 5000' and 9.97 @ 136 mph 1/4 @ 5000' through a Glide and 4.88 gears on TOYO 32x14x15 tires...
It ain't the fastest, but it's gettin' there & it sure is fun to drive...

Very respectable times Doug.
According to Wallace calculators if you were at sea level the correction factor shows you at 9.81 ET
