Admittedly, we at Mopar Connection Magazine have a nasty habit of overlooking the LA/Magnum motors – and we know that’s not fair. The venerable 360 small block carried Mopar performance for 20-plus-years and deserves it’s due, and that’s why we’re excited to help share the news that Proform is offering a rock solid OE replacement for these engines.
For those looking for a factory-style replacement harmonic balancer, Proform’s new dampers fit all 1971-1995 & 1994-2003 engines. These new (not refurbished) nodular iron balancers offer precision fitment and reliable performance (with clear, legible timing markings) that won’t break your budget. Just visit Proform and look for part numbers 66506 and 66507.
Here’s the original press release:
