Ford 331 Cubic Inch Stroker Engine - Going For 400/400
The Summit Racing/MCE Engines 331 Stealth Small-Block Makes Big-Block Power - With Room for More!
Marvin goes back to basic high-school physics. Engines are air pumps, he tells us. The power made is directly affected by how much air and fuel we can huff and ignite in the combustion chambers. Induction is the all-important beginning of this process. Marvin opted for the new Edelbrock Performer RPM Air Gap intake manifold, which offers all of the same features as the Performer RPM, as well as getting the manifold runners off the engine for a cooler intake charge. Marvin has also chosen a 750-cfm Holley carburetor with vacuum secondaries fed by a Holley 110-gph fuel pump.
MCE Builds The Stealth 331
We've already addressed many of the important elements of power: the recipe that is the 331 Stealth small-block from Summit Racing and MCE. We've shown you the block, the reciprocating internals, the cam and valvetrain, the iron Ford heads, the induction package, and the oiling system. Now, we're going to address the many fundamentals of a spot-on engine build.
