If you have skimmed through the rules, you may or may not have noticed this new rule for Vortec motors...

§607.3 Vortec Heads. Vortec is a trademarked name for a line of piston engines for General Motors trucks. The name first appeared in 1988 on a 4.3 L V6 that used "vortex technology" to create a vortex inside the combustion chamber, creating a better air/fuel mix. These head have been paired with a “Marine” style intake in the past.

§607.3.1 Legality. The only intake manufactured by GM that will be considered legal is the following:

GM Part#: 12496820

This is a low rise dual plane with EGR provision and dual carburetor bolt pattern.

We've been receiving lots of phone calls about new motors coming into the series with Vortec heads.....MAKE SURE THE PART IS LEGAL!!!

Any questions, contact Rick Collins, 484-368-6801, or myself, 267-767-4923.

Thanks!
