Info

This is garage sale priced because it was damaged and repaired/sealed by Speedway's engine shop. This includes the carb, distributor and fuel pump shown in the photos.

This engine has dyno time only.  Upon initial dyno run, it incurred a piston issue to where one piston required replacement.  The piston was replaced and then dynoed again with the components included/listed with this sale.  The engine has been repaired and resealed in accordance with IMCA therefore this engine no longer has any GM seal bolts.  The carburetor included wit this engine is a gas carb.

No Warranty, No Returns on Garage Sale Items    

 

Run up front with the 400-horsepower CT400 crate engine (often referred to as the "604 crate") featuring Fast Burn heads from GM Performance Parts. Now, Speedway Motors Racing Engines is offering this 604 crate engine as a dyno-verified package that is ready to race! 
 
These IMCA-sealed 604 crate racing engines are based on the popular Fast Burn 385 street crate engine, but include a racing-only 8-quart circle track oil pan with dual kick-out design, along with a valve cover breather kit and special "kool nut" rocker arm design. The assembly also includes an open-plenum high-rise intake manifold and 1.5:1-ratio aluminum roller rockers.
 
The 604 crate engine includes a bulletproof bottom end, anchored by a forged steel crankshaft and hypereutectic pistons. The 23-degree, Fast Burn aluminum heads enable tremendous power in the small-block V-8 because of a unique chamber design that quickly and completely burns all of the air/fuel mixture – giving you maximum power. With the CT400 racing engine under the hood of your Modified or Late Model, you'll put a "fast burn" on the competition.
