I was in high school in the early 60s and the 427 side oiler was king. once you hear and smell this monster you'll know what I mean...Many ended up in racing boats..

Yeah, a high compression side oiler with a nasty cam will make the hair stand up on the back of your neck when it fires off.

The great thing about the 1960's 427 was it made 616hp with a single 4 barrel setup and 650+hp with 2 4's. The bad thing was the fact it had mirrored cams (in the SOHC setup) and an ultra long timing chain that tended to stretch under the duress of the massive power the engine generated, so keeping the cams in time over long periods was a major PITA. An old friend called them the 45-minute engines..lol
The 428 Cobra Jet was better than the Super Cobra Jet simply because the SCJ version had solid lifters and tended to blow up before the CJ version which used hydraulic lifters.
The bad thing about the FE family (427 & 428) of 7-Liter engines is that they wouldn't interchange fixed bellhousing transmissions with the 351M, 400, 429 and 460's,
Ford's engine "families" restricted interchangeability which made them more expensive to buy aftermarket parts for.

I love the 429 in all it's many versions. I have a 360hp/480ft/lb. 429 from a Mercury Marquis in my 1969 F-100 shortbed which is begging for restoration.
I went on memory from many years back and also shared my own opinion at times.. so if my info is a shade off, my old-timers mighta kicked in
I hope that helped some of you young bucks!!
