Hi All,

I have a GM Goodwrench 350 crate motor (195HP) running an ACES Killshot2, and am planning on upgrading to Vortec L31 cylinder heads. Camshaft is fairly mild, for the time being.

anybody have a VE table for the L31 I can adapt for the ACES? Curious how much it differs from the table I’ve generated for the current configuration.

 

Here is the stock GM VE table out of a 2005 Silverado 3500 L31 350 P59 calibration. Stock Rev Limit Fuel Shut-Off is at 5,600 rpm so the VE table is not calibrated for anything beyond 5,600 rpm.

This VE table is from the OE calibration for VIN# 3GBJC34R95M100001

 

Just found this one as well in my OE calibrations. This one from a stock 2002 Express 3500 P01 calibration. The vans had much better flowing 3" dual pipes to the muffler and the larger cats shared with the 454/8.1L. The GMT800 L31 above had the smaller, more restrictive close coupled LS cats near the manifold exits, a Y-pipe and single exhaust to the muffler.

This VE table is from the OE Calibration for VIN# 1GBJG31R021138833

 

Thank you! Greatly appreciate your help!
