Alek's NA 355 LT1 Z28

Mike Harvey's 1995 Z28

Aleks asked for a topend to transform his over-bore rebuild into a weapon and the numbers speak for themselves.  With a much fatter torque curve than most strokers this is one hot 355.  His setup consists of the same 200 cc CNC LT1's and the Street/Strip Ported LT1 Manifold Rick Abare uses to break records.  With a very driveable solid roller setup this car is sure to get some attention prowling the streets and at the track.  On its initial outing, inlet restricted to 450 rwhp, this full weight M6 car with full accessories (A/C, Power steering, stereo, subs, etc.) went 11.3X's @ 123.5 in street trim.  Updates soon as Aleks dials in the tune and replaces the 12-bolt he mangled (image below).  Expect extremely low 11's at worst and over 400 rwtq by 3500 rpm.

Here's a video of Alek's car on the dyno
