Thread: big block in a 61 2 dr falcon

Tweet

any one know where i can get info on this .

Well, as you probably know, the early Mustangs use the same chassie components as the Falcons, except a few small peices. There may be a kit to change it, with templates for spreading the shock towers which needs to be done, there just too close without it done. Also, what Big block, FE big blocks or 429/460 BBF's? More than likely, there is only a kit for the 429/460. I have seen MII front x members grafted to the old unibody's so the old front can be removed, allowing all clearences needed as the MII dose not have 2 giant shock towers in the engine compartment. My oppinion, get a 260/289/302 and drop in, much easier and with a built up engine, you can make a nice stout motor.

I doubt if anyone is gonna have info, it isn't something that's done every day.

I think if I were gonna tackle it, I'd strip all the suspension off the unibody and use the front (that would accept a big block) and rear clip off a later car, connecting them with 2" x 3" rectangular tubing. I'd cut 2 channels into the floorpan of the car and weld the tubing to the floorpan the full length of the car between the clips. Of course, I'd have the body well supported and leveled so that it would not tweak during all this. It is doubtful you'll find clips that are as narrow as the Falcon, so plan on some fender well massaging and maybe some fabricated flares. Choose your wheels carefully for maximum backset.

Using clips from a mid-70's or later donor car would give you front disc brakes. I'd also get the brake pedal assembly, master, booster and valving from the donor.

Tech, I was on the Falcon registry a few days ago, and most of them talk about using the Maverick 9" on Falcons, those are available new from currie for $1,052 less 3rd member in Summit Racing. I was just glancing through my summit, and happed to see the listing. Granite, 1,000 dollars is a lot of money for that it seems but, he's gonna need a lot of money to do this anyway.

"- he's gonna need a lot of money to do this anyway."

Im not going to bore you with detail but this is my plans so far:
2x3 tubing for the frame, with ifs I will use alot of parts for the frnt from a small metric gm car all the rest Ican make as far as the chassis goes also I have a 502 bbc sitting here with out a home so I decided to put it in my 61 falcon. I can shorten any rear end with a jig I made so thats not a problem either. It will also be tubed and think I will fab inner fenders my self just needed to know if anyone nows if there is any kits I do plan on running a mid-plate.

cost has nothing to do with it .

Sounds like a nice project 61 falcon. Tech & Matt are on target. I done all of that to my 67 couger, I cut the shock towers out, and install a mustange II from Rod & Custom, Art morrison has some nice front end and rears also. I install subframe connectors from ddautospec/stroker.html, They have a lot of suff for the BBFs, but good luck with the chebby anyway. Went with a new ford 9" locker for the rear narrow just a few inches didnot want to do any tubing. I'm in the mock up stage now making everything fit, from the steering to the radiator. I went with the electric fuel pump because I'm hard headed, Which means I had to go with a big rad with two 13" pusher fans to keep everthing cool. If you go with a mechanical pump you may not have that problem. Sounds like you are petty handy with the tig, mig, and stick welding and plasma and grinder cause you are going to need them.

Morrison has some great stuff.....he does quality work....been thru his shop.........cool.

I'm sure I've seen a "how to" in a magazine... a few decades ago unfortunately, cuase there were some big block Falcoons done back then.
