Product Details

The Holley EFI 300-660 throttle body adapter plate enables the use of GM 95mm LS throttle bodies on Chrysler Hemi intake manifolds with 80mm flanges. This precision-machined adapter provides a reliable solution for upgrading throttle body size on Hemi applications.

Key Features:

  • Precision CNC-machined from billet aluminum for superior strength and durability
  • 0.669-inch plate thickness provides proper spacing and alignment
  • Adapts GM 95mm LS throttle body to 80mm Hemi intake flange
  • Complete hardware kit and gaskets included for straightforward installation
  • Engineered for proper air flow transition between different bore sizes

This adapter plate is ideal for Hemi engine builds requiring increased airflow capacity through a larger GM-style throttle body while maintaining compatibility with factory or aftermarket Hemi intake manifolds.

I usually have trouble with this, but it was easy

easy, best price

Great and fast service!!

You had the parts in stock on

Ordered on a Monday morning at 10 and on my porch at 11 AM on Tuesday

So I was skeptical due to a lot of negative reviews online, but I seen they had a great price for Toyo extensa II tires about half the price of everywhere else. So I bought all 4 with the free shipping option, and they were shipped to me in 3-4 days each tire had a different tracking number but they all showed up at the same time. So I will definitely use the site again.
