What would you do? Slant performance

Ok,.. here is some real math;

My car in 1992; "72 swinger loaded iron a/c comp. etc,plus 8 3/4,plus wooden console I
fabbed, plus nice short cut pile carpet on console sides& over the ugly "cardboard" headliner
and package shelf that matched the Olds radiant green stripes on my car. Wt. w/me 3200#
w/a full tank as raced FACT.
Trans; bone stock 904, no shift kit, no stall converter, dexronII,no bullshit, FACT.
Engine; '69 slant from my 1st car, .060" over,9.37:1 comp.,lite 2 pc. alum. Supersix int.,
OE 2245 holley [email protected]"Hg depression modified/rejetted, stock fuel
pump,purpleshaft 276/.490 solid- actual net lift .450" and [email protected],6 into1
Mopar header,2.5" all the way out back,1.74/1.41 valves w/only the port entry&
bowls opened,red 340 hp springs/dampner,shortened crane crmoly pushrods.
Rear; '71 8.75 from duster w/4.10's
It should be obvious this car is under carb'd,over geared,needed a stall TC,
a shift kit etc etc etc etc, yet ran 16.0@88mph anyway,so your math doesn't
jive. My math is Mopars bracket racing math,and it has been accurate for any project
I've done,Olds.Chebby.Furd,whatever. and my car did 3/10's better than the "stock"
drivetrain math, but far short of the optimized number of 14.8 for that mph.
Captproblems ride is definitely not "in the 16's" that is all :glasses7: P.S. rear skins were 235/60HR14 Delta Road Max
