Well, first my income. Up to now, i'm not married and living with my parents, and I have no major expenses, so let's suppose, money isn't the most important problem.

What it seems to be the major problem is to find parts to build a rod. I've been searching this week and found there are 4 or 5 Chevys 350, and less Ford ones.
Unfortunately, thay are sold with a car! :-) But all of them are for restoring. So, may be I press de saler to sell me only the engine.
What I have no luck up to now is with transmission. I'll try to search at neighbor country. I'll also look for completely new transmission. I've read at project33.com (really great site for newbies, do you know another one?) he's using a 700R4, and a new differential. I guess they are too big for and almost stock engine, but may be there are smaller.

What is plenty available are those inline 6 cyl. I told you above. In fact I found some 40's chevys and ford coupes hot rodded with those engines. No idea about torque and hp specs, and although I 'd like to get a V8 (BIGGER torque and hp), they are plenty available and it's easy to get spare parts (and racing ones) for them. We have a racing category called "TC" which uses those engines, and get 350+ hp!

Next, the body. I could only find 2 ford A coupe (both 1930, both complete), several ford a pickup and sedan, but just 1 or 2 Chevys from that age, all sedan 4dr. I think that those age chevys were no popular at all. At least not in south america.
So i'll have to stick whit the A model. I'd have liked my rod be all chevy, but it doesn't matter, while it "heart" be a Chevy one. ;-) (big fan, isn't it?)
I found there are many '38-'46 coupes. Nice ones too, but I prefer the squared ones.

I could found no company (here, of course) which builds bodys or frames. It seems hot-rods aren't a big bussiness here.

My plan (up to now :-) ) is to work on an original frame and body. I have to adapt it to the new engine and transmission, then suspension and wheels, then work on the body. I can manage to "rebuild" original body parts with fiberglass, like doors or not too big ones. Then painting, and bolting all together.
Interior isn't a major problem. I have a completely interior from a Renault Clio and it won't be a problem to adapt it, with some changes.

That's all. Please ask me wathever thing I forgot to mention.
