i knew someone would ask the specs on the motor k here goes
performer RPM Air gap(nothing like a performer and also arguably the best intake ever derived (all around) its a dual plane that can breath up top
Bored Throttle body that flows 850cff(stock tb flow is like 400cfm)
Racing head services pro torker vortec heads with fast burn 58cc(vortec 305) combustion chambers, improved ports(over factory vortecs which are already better than any other factory port) and cut for 2.02 intake and 1.6 exhaust valves(stock vortecs use 1.94/1.50 valves
Volant cold air intake
Eagle 3.75 stroke forged crank
JE 4.040 forged pistons(dished)

File to fit rings, clevite 77 bearings, 1 5/8 inch hedman headers(getting them jet hot coated), huge inline fuel pump, adjustable fuel pressure regulator, msd blaster coil, 3000 stall B&M convertor, B&M Shift kit for the 4l60(non E) and also a shift improver that plugs inline with the factory harness and has two stages. Oh yeah and im using 1.6 ratio full roller rockers to get more lift off the cam (stock is 1.5 as you may know) Copper head gaskets reusable intake gaskets .
just getting started
ATI procharger running at 10psi(reason for the dished pistons) intercooled
80lb/hr injectors(factory 454) running at way higher than stock fuel pressure(stock pressure is like 13psi my regulator adjusts up to 40psi, the injectors are the same type as a higher pressure system so they can safely handle the extra pressure.) I have acquired an eprom burner and am getting familiar with tts datamaster analyzing software and will be using my wideband to get a really good tune. the datamaster program records a run and you can just sit and analyze till its just right. burn the eprom and put it in the adapter i have and BOOM dead on tune.
If anyone is wondering why the volant if im supercharging its because im going to put a few break in miles on it be4 flogging.
THINGS I FORGOT
every bolt is ARP head bolts main bolts(4 bolt BTW) Intake bolts oil pan bolts timing cover bolts etc
Those valve covers are cast aluminum and also all 1986+ small blocks had "centerbolt" valve covers.
Summit aluminum timing cover, summit water neck, high volume oil pump....etc.......etc......etc.....
also summit has the powerband wrong on that cam its more like 2000-6500rpm from my experiences in the past with a similar cam
omg im tired i didnt realize how much i had done
BTW its a 388 i believe(never even figured it up) 4.040x3.75X3.14x8=???
