For the typical weekend hot rodder, there are far more important things in life than sporting a flashy or rare high-tech engine under the hood of your muscle car. Groceries, rent, car payment, and utility bills eat up the household's financial margin, and just having a hot rod at all—running or otherwise—can seem like a victory by itself. (Now you ...
If you've bothered to start searching for a small-block Chevy crate engine, then you've correctly deduced that—for the foreseeable future—you're going to get the most hp per dollar with an SBC (although that appears to be shifting quickly in the LS engine's favor). Your next hurdle is to figure out if you want something turnkey, or if you enjoy com...
The 350ci L31 Vortec small-block was produced from 1996 to 2005 and was used exclusively in GM trucks and other industrial applications. With 255 hp in stock trim, it differed from previous small-block Chevys with production cylinder heads that would've been considered high-performance relative to its predecessors. This was paired with a standard h...
The L31 would be the last traditional SBC produced, and it was made in huge numbers for trucks, SUVs, marine, and industrial use (500,000 alone at just GM's Flint, Michigan, plant). As a fuel-injected, hydraulic roller-cam unit, these cores have an exceptional life span, including a low incidence of ring/bore and cam lobe wear due to the superior f...
Of critical importance here is that a Vortec crate engine may be rebuilt with a flat-tappet cam—that's going backwards just to save dollars. In order to hit a "bargain" price point, many rebuilders opt for pre-L31 cores or converting L31 cores (the most prevalent) to flat-tappet cam and lifters because that's so much cheaper.
When looking at price points in the budget realm like we are here, the cost of new roller lifters and high-performance hydraulic roller cam can raise the cost of a Vortec-based crate engine by $500, but such a downgrade to save cash is bad math. That extra cost for roller lifters and a hydraulic-roller camshaft at the rebuilding stage are worth a m...
If the crate engine in question is a Vortec core and was refurbished with a flat-tappet cam and/or non-Vortec factory heads, the rebuilder has left lots of cheap power on the table just to bring you a lower price. How will you know if what's offered is an L31 Vortec SBC? You won't have to—just verify that a hydraulic roller cam and center-bolt Vort...
