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.
