I am working on a 1928-31 frame. I will be placing my 239 flathead w C-4 trans, on my chassis. I want to keep the integrity of the motor with the original fan. Does anyone know where I need to mount the flathead motor mounts on this frame? I am using a vega box and I am thinking that the motor mounts will have be placed behind it due to the front end that I will be using. I am thinking that I need to keep the fan distance of at least 2-1/2" to 3" from the radiator which would place my motor mounts about 9" to 10" from the front cross member. I know that some one with experience has done this. But?..... Thanks, you guys.
9-10" from the crossmember??? Mine are a few inches at most from the front stock crossmember. Get the motor and a 39 style trans together and use a stock a rear end and torque tube to set your motor mounts. then pull it apart and mount your C4 to figure out your crossmember. The motor should just clear the firewall.
Search for my build thread, there are some pics. You will only be a few inches behind the front crossmember. You honestly need all of the pieces together though. Frame, engine, trans, body on frame, radiator and grill shell mounted and tied to body, fan on engine. Mine has about 3/4" space between the intake/rear of engine and firewall and about 1/2" space between the fan and radiator. I am using a 47 flatty though and a generator mounted fan. You will need all the pieces together like I said.
Also, I have the Tardell book. It has a different engine than yours that is used, and a different fan setup. Do not go off of a book or what someone says, those are good for ideas only. Mock it up entirely.
I've got that same book and it's great if you have a 48 or earlier Flathead but just nice reading if you have a later Flathead as far as engine placement goes. I don't think you want the fan that far from the radiator though. I've been saving everyone's 49/53 flathead in a Model A photos I can find that show engine mounts and placement and the mounts are less than 4 inches from the crossmember and maybe closer than that. I'm going full fendered so I can't fudge on radiator placement. Check this thread http://www.jalopyjournal.com/forum/threads/mods-in-a-model-a-if-using-a-53-flathead.575712/ Pay close attention to post #29 and the photo in it.
Meyer is correct. Your going at this destined for trouble. Do a complete mock up with the actual parts your going to use. Screw the book, make things fit as needed. This is how mine turned out and even if I told you where to put things it wouldn't be exact and might cause you issues I didn't have. Even the guys that follow Tardels book to the T have issues. It's only a motor swap, think about it and just do it. Remember,, there are No rules, just some basic guide lines. One Inch is enough clearance for a manual fan. The Wizzard
I planned on a mock up before the final weld on the mounts and trans mount. Right now I have the mounts tacked on 3" from the cross member. It just didn't look right but I guess it is. I was over thinking the with the fan distance and everything else. I'm guessing that the motor mount needs to flush with the top of the frame? It sounds logical to me.
Pist n Broke, on post #7, what are the brackets/crossmembers that the water pumps are connected to? F1?
A said it depends on your waterpumps and they are all different locations and heights. I installed a 53 merc in a 1932 and using truck pumps to run a single wide belt. I also am running a early standard edelbrock intake with a 3 brush generator.. plus the 49-53 motor is a bit longer so mock-up is the best idea
Ben, you are correct. It took just a little trim work but works fine. Once done I will rivet them in. My end goal is for things to Not look hand carved or out of a Box Kit parts.
