Zac_F71's 71 Demon
ok back up - I inspected everything over good - 75% sure both stock heads have stock springs in them as they look identical on each of the heads, (single spring with a damper spring inside)
SO I ordered a pair of stealth heads and will just run them for now.. anyone know the part number for the correct plugs for them? I'm not a fan of Champion plugs, and want to get NGK's.. honestly to me they look like typical GM style plugs that most aluminum heads use..
So here is the FINAL build-
Holley 3310 750 carb
1/2" divided spacer (may switch to open)
Edelbrock Performer RPM intake
440 source stealth heads OOTB (ordered - no going back)
MP shim .020" head gaskets (should be 9:1 static with the flat tops - measured .050"-.055" in the hole)
stock pushrods/ rockers - may buy hardened pushords not sure yet
Comp 280/.480" 110* cam dot to dot
Summit timing chain
stock oil pump from 71
MP windage tray
Milodon 7qt oil pan
stock 71 rotating assembly
440 source crank under drive pulley (5.25" diameter)
440 source aluminum water pump setup w/ HF pump
Proform electronic kit (may just get a dizzy as I already have the harness/box)
Mancini lightweight alternator kit w/ 120amp Toyota alt to run electric fan
80gph mechanical fuel pump w/ reg/filter
Hedman 1 3/4" B body headers, Summit 3" X pipe, 3" Dynomax Ultraflow's dumped at axle
stock 727 w/ hard spring shift kit, 4.2 band lever (factory super stock part)
Hughes 3,000-3,500 stall
Hurst Pro-matic 2 shifter (can get for $120 brand new)
stock drive shaft
B body 8 3/4 w/ 3.23 gears (a gear set isn't in the budget as the chassis needs a lot of work)
^ new green bearing kit for axles - leaving center section as it has lower miles on it..
What do we think it will make? I'm guessing 400hp-425hp at the crank.. but would be happy with 380 crank..
PICS of the $1,000 motor torn down!!
torn down and inspected all good - waiting for parts to tear into the rest!
