Description
 
Heater boxes that will not only perform, but actually heat your car!

These High Performance 1 5/8" Heater Boxes have a full-length cast aluminum heat sink to maximize heat transfer just like OE style. Now you can run ported big valve heads without choking down the air flow at the heater boxes.

The High Performance 1 5/8" Heater Boxes feature a grey powder-coated heavy duty stamped outer shell and an extra pair of laser cut 2-bolt flanges to weld on and match-up to your 1 5/8" high performance header system. Mounts up to the original levers, bellows and factory lower cooling tin.

Choose wisely - Other 'Performance' Heater Boxes on the market lack the OE style aluminum heat sinks and therefore may provide insufficient heat for your needs.



Cable lever arms and hardware kit CB# 3687, sold separately.

5 of 5 1 5/8" Heater Boxes, best made heater box availabl August 6, 2019
Reviewer: Westy Restorations from Utah  
If you are building a bigger engine and want heat with proper flow, these are the heater boxes to get! The quality on these heater boxes are incredible, thick steel, quality paint, and professional looking assembly make them the best on the market. They look and feel better than the Dansk stock boxes and way higher quality than the lightweight 1 1/2 boxes without the aluminum heat sink. Was hesitant at the price but after receiving a set we would get them for all big engines, definitely worth every penny and will last a lifetime.
