the mad scientist at work.... transforming a sluggish slowpoke into something to be recon'd with....
Engine teardown begins, Pistons and cylinder walls after 12k miles:
GT11 Boost friendly camshaft for a LS3 conversion.
Lingenfelter LS3 CNC ported complete cylinder heads with light-weight hollow stem intake valves and heavy duty inconel exhaust valves that are designed to be durable even under extreme high temperature conditions seen with supercharged or turbocharged applications.
LS3 cylinder heads are precision CNC machined on a 5 axis CNC machine to ensure that tight tolerances are maintained. The Lingenfelter CNC porting procedure is a computer controlled machining operation that duplicates details from a finished Lingenfelter hand ported cylinder head. The port and chambers are carefully designed to provide the best combination of high flow capabilities across the entire valve lift range. The Lingenfelter quality control procedures include sectioning sample cylinder heads to confirm minimum wall thicknesses.
Following porting each head receives: Precision 3 angle valve job to maximize flow & provide extended life, CC checking chamber size for correct compression, surfacing to insure deck flatness, deburring, pressure testing, professional assembly, setting spring height & checking all tolerances, and serial number:
