Interested to see what a simulation would show.
Rick as requested.
Dynomation 6 Input Variables
Bore & Stroke: 4.00 X 3.622 (LQ4)
Displacement: cubic inches: 364
Rod Length: 6.098
Heads Make/Model with flow numbers: Flow (CFM) at several lift points.
Combustion Chamber Size in CC’s: 62
Dome Volume: For a domed piston use a (-) negative number. +6.7 (dished)
Valve Relief Volume: For a piston with valve reliefs or dish, use a (+) positive number. see above
Deck Clearance: (Piston to Block Surface) - not measured... assume 0.00"??

Header Tube Diameter: 1-5/8", 1-3/4", 1-7/8", 2.0" - 1 -7/8"
Cam Part Number: Elgin E-1840-P
Cam Specs: Need all 8 valve timing events at seat-to-seat and at 0.050” plus lobe lift or valve lift OR post Cam Card OR give me what you have.
0.006" and 0.050"
Rocker Ratio - Intake/Exhaust: 1.7
Cam Installed per Cam Card, or Retarded or Advanced: as per above, installed as per card with ground in 4 degree advance
