I am considering putting a 460 in my 54 f100. Currently it has been mocked up with a 302 with aod. This would be a good general driver, but have moments that the big block sounds better. I think I would need to recess the firewall. I'm sure this is a common setup. How much setback has everyone used?

 

I put a 460 in my 55 and didn't touch the firewall.Fits fine.

 

several of the guys on here have got 'em in there's and i dont recall seeing a recessed firewall in any of them . i was gonna put an fe in my 55 and i wasnt gonna have to recess it either after i got it all fingered out . theres all kinds of room in these girls for anything . hades when i work on my flatty in the 53 i just crawl in and stand next to it ............ one of 'em wiil bealong shortly and there was another thread about the same thing here not to long ago so maybe do a thread search on the 460 .

 

I also don’t think you have to, hope not, as I am going to be putting a 460 in a 51 f1. Here are some dimensions off the net, not guaranteed of course.

Length from fan pulley to rear of oil pan;

Flathead - 30 inches; .......302 – 29in;.......... 460 - 34in

 

Here's to another big block....
