Schumacher’s Big Block Mopar Tri-Y Under Chassis Headers

Everybody with a little bit of grey in their beard (or more) will know the name Schumacher Creative Services Inc. as being the go-to source for engine swap motor mounts, but to leave it as that is to discredit nearly half of Schumacher’s catalog of Mopar parts and services.

If you’re not already a subscriber to Mopar Connection Magazine’s YouTube channel, you might not have been up-to-speed on our 1970 Plymouth Fury III convertible project “Marsha”; a big ol’ cruiser that we fished out of a tabacco barn in June of 2022.

Equipped with a very injured 318 and slipping-and-sliding 904, our Fury was in pretty sorry shape. Packing several pounds of body filler covering up some pretty ugly bodywork, we quickly realized that this Plymouth was gonna need a full-blown overhaul.

Minor upgrades couldn’t reverse years of mistreatment, so we sent her off to Dave Chamberlain of All Classics Restoration to patch the floors and trunk, and straighten her acres of bodylines, while we assembled a roadworthy powertrain consisting of a bulletproof 727 TorqueFlite and warmed-over 440.

And that’s where Schumacher’s Big Block Mopar Tri-Y Under Chassis Headers came in to play. Priced at $899, Schumacher’s headers provide high-flow header performance and a precision fit for all big block engines (361, 383, 400, 413, 426 Wedge, and 440). Remarkably, these also fit great with most aftermarket aluminum heads with angled plugs. Best of all, they don’t capture the starter!

Moreover, these fit with manual or power steering and either a manual or automatic transmission; install quickly and painlessly, and are made entirely in the USA. These are short tube headers, so you’re keeping all of your low-end torque, ending in a 2.5 inch, 2 bolt, collector flange and gasket.

We haven’t installed these yet on our ’70 C-body but when we do you’ll see it at Mopar Connection Magazine’s YouTube channel with a follow-up story here at
