I have had many 350 Chevy engines and they are great. Are they 5.3 liter, 5.7 liter, do they even make a motor with the same displacement and design? The 454 was trash. 327 was excellent but to small.

Asked by Jun 27, 2015 at 04:00 PM about the Chevrolet Silverado 1500

Question type: General

I have had many of the old 350 Chevy engines. Love them. Do they make an engine that
has the same spec's as that old engine? The 327 is a good engine but lacks pull power
for towing. The 454 was just junk. The specs on the old 350 were a perfect match of
stroke length, displacement, cylinder size, etc. Do they make that motor anymore?

Sorry to say but the old 350 or later called the 5.7 is dead. The replacement 5.3 seems underpowered even compaired to it's closest engine the 327, it acts like just a standard old 305. But I have to disagree with you on the 454, if you matched it up with the right gearing it would pull like mad, you just had to watch the RPM's.

The new 5.3 is way more powerful than even the last 350 (vortec). 310hp isn't enough for you? It is part of the ls family, not the conventional small block. Comes out to be a 323 ci
