Re: 425 Buick Nailhead Wildcat
Anything is possible with a little fabrication.

Re: 425 Buick Nailhead Wildcat
I think it would be an awesome swap. You would most likely have to do some firewall recess work and manufacture a transmission hump, but well worth it for the "different" factor.

Re: 425 Buick Nailhead Wildcat
Hells ya, go for it. I mean, if you don't mind fabricating, and hunting down parts.
I wanted to do an early 70's pontiac 400, but the only one I found was in horrible shape. |

Re: 425 Buick Nailhead Wildcat
That's the exact swap I was considering for my '52. It's different, nailheads make oodles of torque and they are narrower than big blocks due to head design. Find a 200R4 and you have an easy overdrive trans swap. Go for it!

Re: 425 Buick Nailhead Wildcat
It would make a good swap. with the right rear end the truck would be able to show the big dogs the way home.
I'd have to want it to be in great shape for that price though. If it needs to be rebuilt you will learn real quickly while the "belly button" 350 Chev is the most popular engine to swap. I'd figure out what gear ratio was in the donor vehicle and stay pretty close to that ratio. The overdrive transmissions are nice but it is hard to beat a 400 for reliability and they are easy to have fixed if the need comes up. Plus with that being a Buick/Olds/Pontiac/ Cadillac bell housing transmissions are easy to find used in good shape. Last edited by mr48chev; 09-14-2009 at 07:20 PM. |

Re: 425 Buick Nailhead Wildcat
I am going to go with the Nailhead instead of the Caddy 390.. It's going to cost me more to get running and looking good but I think it would be more of an eye catcher when I open the hood.

Re: 425 Buick Nailhead Wildcat
Had a nail head 364 in a 50 f1. Very quick. A 425 will be a blast.
I would do it again in my 59 3100 if I already didn't have my 0 mile 327. Last edited by Number 9; 09-26-2009 at 04:44 PM. |

Re: 425 Buick Nailhead Wildcat
Pick up the latest issue of "Hot Rod Deluxe". Terrific article on rebuilding/hot rodding a nail head. Cool motor. I'm thinking dual quads!!
