After roughly a year of rebuilding both my 440 and 727, the day finally arrived to break-in the engine yesterday. The machining was done by Dougan's Machine Shop, well regarded locally here in SOCAL/Inland Empire.
440: 68 drilled .030 over, steel crank (from 68 Imperial donor), stealth heads, SRP 10:1 pistons, SCAT rods, stock manifolds, MP HD rockers, Lunati 60303 cam/lifters, hemi pan, 71 repro carbs, rejetted center to 65, TTI 2.5 exhaust. Calculated static CR: 10:2; dynamic CR: 8.4.
727: 4 pinion planets, Transgo street shift kit, deep pan.
Test stand: engine/trans sitting on K sitting on rolling dolly (will install from underneath). Using recored 856 radiator, repro Mopar AGM red cap battery, and 60/40 mix of 91 octane pump and 110 leaded race gas. Attached slip yoke and wired tight. Plugged dizzy vacuum advance and all open vacuum ports. Box fan attached to front radiator frame.
Pre-start: Castrol 20W-50 oil with half quart of GM EOS additive, 6qts Dexron in 727. Set dizzy at points just open on #1 at approx 14BTDC. Water only for cooling. Primed oil pump while slowly rotating crank 2 revs. Filled float bowl through vent tube.
1st startup attempt: starter engaged just briefly, then nothing
Suspected power supply issue
. Relocated battery to eliminate a jumper between engine and battery ground.
2nd attempt: fired right up
Set to 2500rpms and ran for 30min with occasional bumps in rpm. Filled trans. No leaks. Set timing to 36deg at 2500. Shut down and let cool, then drained oil. Video of the breakin below on youtube.
