454 bbc swap
Anyone know of mounts to use or anything I should know about for a putting a 454bbc in my 66? I know I need to change out my drive line and rear axle comin down the line soon maybe a dually rear?
But if there is anything I should know about the swap (such as a rumour I heard that I would have to cut the fire wall out for it. Please let me know before I invest the money in the budget rebuild?

Re: 454 bbc swap
I used the mounts out of an 84 Chevrolet Suburban 3/4 ton. Had to knock the firewall back a bit to have enough clearance.
Here's mine http://youtu.be/qxMTLCRuEa0 By the way it's hooked up to a 400 tranny and i had to find a drive shaft and cut it down to the right length. Got rid of the carrier bearing. Last edited by Newold65; 04-18-2014 at 01:34 AM. Reason: More info |

Re: 454 bbc swap

Re: 454 bbc swap
To be honest literally beat it back with a hammer at first. Lol. then went back in after I pulled the engine to do a crossmember swap and cut and then rewelded. I've seen some guys move the motormounts forward and avoid all of that but I can't seem to recall who it was.

Re: 454 bbc swap
Mine went in without firewall clearance issues, but, I also have short valve covers on it.

Re: 454 bbc swap
No problem....actually working on two big block swaps. Other 63 is a short fleet and will be getting a 1st gen 348 installed. Stay tuned to the build threads for updates on the conversions and let me know if I can help any.

Re: 454 bbc swap
I just set mine on my frame today to look at it. It's frame only but I'll be moving mine forward to the other bolt holes. Worse case scenario I'll have to drill a bolt hole in my Zk member. Which I have to switch out first anyways to convert to 5 lug.
