A few questions about a build I want to start soon
I've been thinking this out for a while and I want to start a build on a 351w based motor with a 5 spd behind it. I've currently got a built 5.0 with a centrifugal supercharger and an AOD behind it. I'll be selling the current motor and tranny most likely to get this project rolling. I'm looking to build something with 450-500 hp, carbureted, it's most likely going to be stroked. It will be a street car and I want it to run on pump gas. But I need to start at square 1 with finding a block. I don't want to build this thing with cheap ****ty parts either, I've seen where that has gotten me before and I want to do it right the first time. So I need to start at square 1 and find me a block. Which of the 351Ws are the good, bad or the ugly. I'm not going to spend the money on a Dart block because I don't believe that I will need one. I'll be hitting the junkyards and craigslist pretty hard though. Things such as what years or what vehicles and what kind of horsepower they will handle would be helpful. Next question, I've been an AOD guy for a while and know them pretty well but I would like help on trying to figure out what 5 spd I would like to put behind this beast. I know this is going to be a costly and probably a time consuming build because I don't have money flowing out of my ass but I think it would be fun in the end none the less. Any help and useful suggestions would be great!

the preffered 351w blocks are 69-70 (c9-d0, which have a 9.48" deck height)
They are by far the strongest available OEM 351w blocks.
Next you have the D1-D4 (71-74) blocks. These too have a high nickel content and are quite strong.
anything D5-F3 (75-93) you should just avoid. they arent the greatest of blocks, if you cant find something 69-74, start looking for a 94+ as its the same as a 75-93 block... except its a roller ready motor.. which is a money saver!

I would look for a 1994 or newer block so you can run a roller cam. I started mine with a 94 lightning motor (that actually has a flat tappet cam in a roller block) I am saving all the parts I tore out of it for a project that has yet to be determined.
I picked up a 408 stroker kit and off I went.
I am not a fan of any 5 speed for racing but its up to you. I have a C-4 that I had built to 600 HP with a 10 inch converter stalled at 3500 that has been tore down and furnace brazed. It also has a transbrake with a full manual reverse valve body.
let us know what you come with.

a faceplated TKO600 wouldnt be all that bad of a choice
I am sure a faceplated TKO 600 would easily be the best choice for a 5 speed. I guess the bottom line is how much money do you want to spend. That tranny is going to run you around $2500 with the faceplated gears.
My C-4 and converter were professionally built, are guaranteed to over 600 HP and are actually warrantied by the builder. I have $750 in my tranny and adding the transbrake put me up to around $1000.
As long as you get / build a tranny that can hold the power you will be making it is all personnel preference. Just don't be that guy that tosses a T-5 behind a 408 and then starts a thread "I don't know what happened to my tranny" when it blow up

Okay, so i went cruising the junkyard today and stumbled upon a 67 cougar with a 351 and a 4 spd toploader in it. I know it's not the stock motor. I couldn't find any numbers on the block except for 351 wcp 9 stamped in the lifter valley. Anyone know anything about that? They said i could take it all for 75 bucks so i figured what the hell i'll take it. I'm going to pull it all out tomorrow. And see what's up.
So the motor is sitting in the bed of my truck. Well it wasn't a block that I was hoping for... cast no. on the block is E9AE-6015-AA-9 . How much power will this block hold? I know the 1989 was not the strongest or the most desirable blocks but can I make a reliable 400-450 hp motor with this?
