Trying to identify engine and Trans

For anyone who helped me out with my first EB purchase, I want to first say Thanks a ton.
Well, after that less-than-positive experience purchasing and ultimately returning my first EB, I already looked at another one today. Test driving it tomorrow, and I want to put together this puzzle on the engine before I consider making an offer. Also need to know how to find and interpret the stamp on what he says is an NP435

The guy says the PO installed a 351W block from a 91 crown vic. In his book of receipts the only thing I can find relating to that is one page of an ebay add for a used windsor (dated Jun '03), and installation instructions for an edelbrock intake for 351 (dated Jun '99).

However I found receipts from summit racing for JBA headers for 289 or 302 (dated Aug '05), and one for with radiator hoses for 302 (dated Jul '06). There is also an aluminum radiator installation page, which has one paragraph about how 5.0 engines require 87-93 5.0 radiator hoses for that install.

Seller has only had the truck since August. I'm thinking this means he got lied to and there is a 302 under there. I wouldn't mind having a 302, but I will offer less if I can identify it.

Found the codes for identifying an early 351 W on another thread. But I can't find the code for identifying an early 302 or a '91 351W. Any help would be greatly appreciated.

the deck of the block is taller on the 351w and the firing order is diff.the firing order for a 302 is 1-5-4-2-6-3-7-8(counter clock wise) and the 351w firing order is 1-3-7-2-6-5-4-8(counter clock wise). the block are the same size for the 302 & 351w just that the deck is taller on the 351(taller from the water pump port to the top of the deck) is like an inch taller. i tryed to upload a pic but it wont let me. btw when i got my bronco the P.O did some stuff to the motor(302)like cam,and heads and intake etc, and hes musta put a cam for a 351 one in cause that the firing order that i have but it a 302 block. oh you saked about the headers fitting a 289 & 302 well thell fit the 351w as well. good luck hope this helps you out

is it carb'd or EFI? looks like ford did offer a 351 in '91, but it was only available with a carb. on the 302 the dizzy base is even with the bottom of the intake, on a 351 the intake is about 1" higher than the dizzy base.

A 302 is about 9" across the front of the intake
A 351 is about 11" across

Thanks, guess I better bring my ruler

It's carbed. I'll check out that base too

I dont think a 351W adds more value than a 302 or 5.0. I think many folks would rather have any engine that runs well. A newer engine, with documented low miles, is worth more than an engine with an untold number of miles...thats about as much as you can say. All things being equal, identical truck with a 302/5.0 or 351W. I dont think they would price any different. Unless, of course, your willing to pay more...I wouldnt be. I would pay more for EFI...but ultimately, its how well the truck performs--as is. Many things more important than the motor when buying one of these trucks. A motor is a breeze compared to rust repair.

I pretty much agree, but if it's a 351 rebuilt from a '91 crown vic that has been swapped in as opposed to the original 302 it's most likely going to be in newer, better shape.

This one had rust, but all the floorpans have been replaced with thicker sheet metal and rhinolined over. There are a few spots i.e. inside of door jam that are kinda thin but it has all been treated with POR and Rhino Line. The underside of the truck could use a good wire wheel and POR job and I can do that.

Block ID number will be on the block up by the starter. I have a book with the block numbers but you should also be able to find them online.

I wouldn't agree with that. Newer, yes. Better shape? Maybe, maybe not.
Get the block number and you'll know exactly what motor it is, which will let you know lots of related info.

Thanks for all the help. I didn't get the block number, but I did measure the intake manifold and it's a 351. It runs really smooth, too, just needs a little carburator adjustment.

sounds nice. take some pic's!! we wana see!!

Will do! I actually ended up buying it today and got it titled and registered! Good to go and I got a pretty good deal, I think. I would post pictures now but I dont have access to a digital camera. I'll post 'em when I get back in town on Sunday or if I get a camera tomorrow. She's a beaut!
