This is my plan to build an engine for my Suburban as a replacement. The stock motor is still fine, just old, but I want a backup motor with a bit more kick in the pants.
My goal is a torque engine, good power, nothing high rev, thinking 5000 max rpm. Messing around with a couple pieces of dyno software I think I can expect something around 260hp and 350ft-lbs tq.
Block: 14010207. 80-85 350 block, cars/trucks, 2 bolt main, .030 over. Rebuilt with all new bearings, new 30 over pistons, polished crank.
Heads: 14102193, stock TBI heads. Going to be port matched and polished, and gone through pretty good. Gonna clean up the chambers, unshroud the intake valves a bit and smooth out the spark plug bosses.
Intake: Stock TBI intake, port matched and polished with ultimate modded TBI sitting on top.
Cam: Edelbrock 3702 TBI cam, installed straight up
Valves springs: Edelbrock 5802 springs, 80 lbs. Comes with the 5894 valve spring and retainer set.
Rockers: Comp cams 1417-16 Set, Magnum roller tip rockers 1.52 ratio.
Valves: Summit Racing stainless undercut, 1.94/1.50
Fuel Pump:Vortec pump EP381, running 15-16 PSI at the injectors (will adjust as needed)
Computer: Custom fuel maps using Moates.net APU1 adapter, Wideband O2, and Tuner Pro RT
Timing: Edelbrock 7800
Head gaskets: Felpro 7733PT-2. 4.125" bore, .039 installed thickness
Intake Gaskets: Edelbrock 7201, keeps all factory ports open for EGR and heat port for intake.
Ignition: Accel cap/rotor/wires/coil, CR43TS plugs gapped at .042
Exhaust: Full Hooker. Long tube headers, 2 1/4 true dual, comp mufflers, no cats
