Hey Bill,
Many of the 390s (Especially the 390 GT) got a bad rap. The GT version fell into two different categories with no in-between. Either they ran like a scalded ape or like they were towing a load of bricks behind them. They suffered from intake, heads, and exhaust manifolds better suited hooked to a chain hanging from a boat. The 428 CJ received a better intake (still cast iron), 427 L/R heads, freer flowing exhaust manifolds, and many other improvements. This was all done using the same camshaft as the 390 GT, so you can see how carefully selected pieces to a puzzle can come together and make one formidable engine on the street and track.
A shout-out and a "Thank You" to Bob Tasca Ford, who, on their own, assembled race-proven already existing Ford parts to create a high-performance Mustang they named the KR-8. The Tasca-built prototype was enough to wake Ford up, and the 428 Cobra Jet was born. And as they say, the rest is history.
Since you mentioned the engine was already built when you acquired your Galaxie, it appears to have the cam, aluminum intake, headers, etc., and most of the bolt on's most often installed first. I would take Chuck's (c9zx) suggestion and try a more aggressive gear. If used mainly for cruising duties, a rear gear change would be very noticeable and make cruising nights much more enjoyable.
I would avoid heavy truck FE (FT) engine parts. Granted, they are more robust, durable parts, but they were engineered for medium/heavy truck, industrial, and power production use. The blocks, rotating internal parts, and other cast iron components are very heavy and were not meant for any high RPM use. Most of these engines were carburetor/distributor governed not to run over 4,000 RPMs. Way too heavy and slow for automotive use. The 389/391 engine did use a Steel crankshaft that some have tried in automotive applications, but the front snout had to be turned down since it was larger on the trucks. There was a problem with some of these steel cranks breaking in the area where the cranks extend from the front cover.
The "Lemans " rod was not used in any truck engines. This unique cap screw rod was initially released in '62 for the high-performance 390 and 406 with special crankshafts. It saw continued use in the 427 and was the production-installed rod used in the SCJ 428.
Appreciate you and Idaho Chris posting pictures of your Galaxies, as I am a big fan of the Galaxies from the 60s! And.....If more pictures of them were to show up, I certainly would not be offended!
