Here's a link to an article I recently did for Auto Enthusiast Magazine where we tested a genuine Holman/Moody 427 Tunnelport that was about as virgin as you can get.

Not that I did anything special...I just think it was really cool to get a chance to be involved with an engine that has this pedigree and history behind it.

It's owned by a member here...Victor Cotto. From the start it was determined to put it back together just as it had been run "way back when" using all the original parts possible and not doing anything at all to change HP. We wanted to see what it really did. Somewhere along the line (probably early 70's) the cam became the Ford 242* flat tappet instead of the 260* one that had been in it..but it still turned out cool and now we can see what they really did *back in the day*.


The headflow numbers and dyno sheets aren't showing up in the on-line version...but they do in the paper one.

my landlord started collecting 427 engines back in the 60's. he has several tunnel ports and a cammer. i'm trying to talk him into putting the cammer in a 65-66 mustang fb. he wants to put it in a 66 4 door custom ! the 427 fe is a cool engine.
