Hey guys
This is the engine me and my son built for his 71K10, 373 gears 33" tires.
Tell me what you think.
We have started it and broke in the cam but not driven yet.
'83 4 bolt 350 from 2500 truck
bored .040 over, decked.
line honed, Eagle cast crank
Scat forged rods 5.7"
KB -18cc D cup, .040 quench, moley rings.
New Stock oil pump.
SFI flywheel and stock 6.5 balancer
Whole rotating assbly balanced
GM Perf parts #8060 vortec heads decked .010-.020 ?, port matched to intake, combustion bowl left stock, intake and exhaust passages ported, , area around valve guide smoothed/ported, including short and long radius.
Restricted area under valve anlge enlarged. Mistake here? should I have left that alone?
Pocket cut for LT4 springs/retainers, viton seals, screw in studs, guides plates.
CAT alum 1.5 roller rockers, new std lenght push rods.
Comp Extreme 4x4 Flat Tappet cam X4262H .218/.226 @ .050 LCA 111 .462/.480 107 ICL Degreed out straight up.
Comp flat tappet lifters
ZZ4 water pump, take off from crate.
Edlebrock RPM air gap Vortec Manifold
Barry Grant Speed Demon 575 Mechanical with annular boosters and electric choke kit.
Cheap ebay red top ProComp? Billet HEI dist, for now.
Hedman Elite coated Headers, Cherry Bomb Vortex , 2.5 ss all the way.
Fel-Pro gaskets, all.
I think compression came in around 9:1-9.25:1 after cutting the block/heads.
I think I got everything
PS I forgot to check the rocker geo for push rod length. Probably need shorter? because of block and head surfacing?
I know I know, heres the question How about Opinions on TQ/HP and general build suitability.
Thanks fellas
Happy Thanksgiving
Chas
