SB Street Krate

Muscle Motors Small Block Street Krate

This is the small block version of our tried and true Street Krate.  This 440 HP, 500 ft/lb torque small block is well mannered enough to drive across country yet can be obnoxious enough to get the attention of the local Sherriff if you want to misbehave!  We start with a 360 block and do our usual race preparation of the block.  This includes a sonic check of the cylinders, align honing the crankshaft journals, parallel decking, and cylinder boring and honing with deck plates to ensure a precision machined, durable short block.  We then install one of our pump gas, street 4 inch stroker rotating assemblies.  This cast crank kit is cost effective and is practically bulletproof under 5500 RPM.  The forged I beam is light weight and helps these engines rev faster than a 340! Since this is a “Street” engine we design the cam to reach top power and torque by 5500 RPM so it works great with 3.23 gears.  With the 4 inch stroke and more than 440 HP, these engines make AWESOME torque yet fit where are 318 might have been.  Can you say sleeper?  We then finish filling the short block with a Comp Cams timing chain, camshaft and lifters.  A Melling oil pump keeps everything lubricated and a Mopar Performance distributor drive and timing chain tensioner keeps everything timed properly.  A new oil pan and pick up complete the bottom end.  All assembly information is recorded on a build sheet by one of our experienced engine assemblers.  Anyone who assembles an engine here @ Muscle Motors has over 20 years of experience!!
