1951 Chevy Pickup Big block swap

I'm getting into a new project. I'm planning on putting an early seventies 454 into my 51' chevy pickup. I know parts for a small block swap are easy to find, but i'm not having much luck finding swap parts for a big block (mainly the mounting crossmember). I'm wondering if anyone has any advise on the swap or leads on parts? Thanks!  

Call up Brothers Trucks or LMC Trucks, they should sell the mounts you need.  

Classic Industries and The Truck Shop both have a V8 conversion crossmember. This should be universal with small blocks and big blocks considering you can swap a SB and BB in and out of 60's and later trucks all day long. Just buy the correct mounts for a big block and it should all bolt up  

Any updates NicholasG on finding those mounts?  

Thanks a lot for the info.  

I found a lot of good parts at classicperform.com. I also found out I have a street rod shop across town who I will be contacting soon.
If you all have any advise on what can be done with the front end. That would be awesome. The rear end should be simple with and axle conversion kit, yes? I'm wondering if anyone has done something other than a control arm swap in or a mustang front end swap. I don't really want this truck to be lowered. Maybe something cheaper. Like a front strait axle from a 4X4? My goal is to put disk brakes up front, at least, while still being able to pay for schooling. I plan on this truck being capable of being a daily driver, and performing on a track... at least as well as a truck like this ever could without tens of thousands of dollars.


Thanks for any advice you may have or tricks you may know. It's very helpfull.  

If you want the front end low, you DO NOT want a 4x4 axle.  Either an IFS swap, or a drop straight axle will get you in the weeds.  There are coversion kits available, to put disc brakes on your spindles.  Tossing a drop beam in the middle will be easier than IFS, but very few shops know how to align a straight axle.

Be sure to keep math & physics in mind, either way. Scrub line is something you need to study on. For safety's sake.

I'm thinking I will go with the hub disk conversion on my current spindles. I guess I had it in my mind that may not be the sturdiest rout? I'm also not familiar with the term "scrub line", and am not finding it in my search engine.  

Lets see if I can help define:

Scrub line.. how low can the axle go with out becoming a plow..  right Pack?

'scrub line' is an imaginary line running from the edge of one tire, to the opposite wheel.  Basically, anything below this line will 'scrub' the ground, if you blow a tire.  This can make it difficult or immpossible to safely stop after a tire/wheel failure.  Not to mention damage to other suspension components.

Some people, ableit extremely conservative, use the opposite drum/disc, to be safe, in the event of a lost wheel.


And a cookie to olblue, for the nice simple explanation of a complicated geometric equation.
