TPIS MiniRam (383cid) intake vs Holley StealthRam (350cid)

This test compares my 383cid motor with a TPIS MiniRam intake, with a  Holley StealthRam (HSR) when it was on my ZZ4 (350cid) motor.

The old engine was a ZZ4 crate motor, AFR190 heads,  LT4 HOT cam, and SLP 1-3/4" SS headers.  Trans is a 700r4 with a Vigilante 3400 stall converter.  The Engine Control Module (ECM) was a '92 TPI stock ECM (MAP/speed-density) with a modified EPROM.

The current engine is a budget build 383 short block, with my old top-end. (AFR190 heads,  LT4 HOT cam, and SLP 1-3/4" SS headers).  The Vigilante has been reflashed to a 2800 stall after being rebuilt with a Kevlar 5-disc lockup clutch.

*The 383/MR run had a road-racing (rich!) chip with a 95mph forced TCC lock.  This should have caused the ET to slow and the MPH to increase.
