Engine upgrade for my 40

I recently procured a new motor for my 1940 P/u. I anwsered an add on CL for a 302 w/C4 trans. I called the guy and he had it still so I went an dlooked at it. Now I am mechanically inclined but can't ID a motor on sight. We turned it over and it had compression so I decided to take it. It was only $200. He helped me get it on a stand and I got it to the house. My engine stand was not that great and bent from the motor being in the trailer so I couldn't tun it over to check the block number. Long story short, I replaced the bent part this weekend and onec I got the motor turned over and looked at the block number I found it to be a 351W out of a 69 Mustang. Pretty sweet!

Sounds great.... I'm pulling the flathead out of my '41 and building a 5.0 H.O. roller moter (same block as the 351W). Keeping the C-4 I have backing my Flathead etc.

Good deal! I'm replacing the flathead in my '46 this summer with a small block Ford and rebuilt C-4. I love the looks of the flathead, but the demands of daily driving in SoCal call for something a bit better. Gonna wrap up the flatty and hopefully use it in a traditional type rod sometime.

Thanks, I was attempting to convert the "302" to a rear sump and when I was putting on the new pick up, it wouldn't fit quite right, As I was sitting there staring at it, I noticed the block numbers. That's when I looked them up. Unfortunately I now have two oil.pans that won't work and don't need along with an oil pick up.
Now I have to decide on an electric fuel pump and water pump versus mechanical. Any thoughts?

I'm going with an electric fuel pump, mechanical water pump, electric fan, in my 302/C4.

I'm thinking of the same thing. I like the idea of an electric water pump as well. My fuse block can support it. What would be a draw back?

I run electric fuel pump electric fan and am installing the vintage air front runner pulley system with water pump a/c and alternator all included.

I'm only the 2nd owner of my '47 so I plan to keep it bone stock right down to the dark green paint and sick yellow trim. The flathead might have its limits but it took me a lot of miles before I decided to do a full resto. I do intend to balance and blueprint the engine and maybe run dual exhaust but that's going to be my limit.
