413 q
« on: November 21, 2006, 01:59:03 AM »
so a fellow tells me i can buy a good running 413 from a 74 ish 's 3  or 5 tonn not to sure wich.  i looked at it and it is a big block, but i'm unsure if it is a 413, for $250 canadian i can get the eng and 5 speed  manual from this truck. 
what kind of power would this engine have?
if i put in a cam that was a step up and headers(already have) think it would be allot of fun in a 4x4?

That would be a 413 industrial engine more then likely.  Industrial engines are suppose to have 2 oil filters and a 8 bolt flywheel.  If thats the case your pretty much stuck with using that 5 speed also.  The 413 is a low rev torque monster.  Headers would just give it more torque.  It might be fun, but dont' expect it to rev like a 383.

I know a guy who did a swap like you are considering.  He told me a few things about it.  His transmission was not an overdrive.  First gear and high gear had about the same ratios as a 435 tranny.  The extra gear just made the engine drop less rpm's per shift. 

He also said the crank on his engine was drilled different than the cars and pick-ups, so he had to use the truck flywheel.  The truck flywheel required the heavy truck clutch, which only fit the 5 speed transmission.  So a little fabrication on the clutch linkage or the transmission mount is going to be required.

I'd also check to verify it's a 413, some of those trucks used 361's as well.

My friend was very happy with his truck after the swap.  He ran it for several years.

the interior of the cab and the cab itself looked just like a pickup,   i dont recall the big block looking goofy at all, but i wasnt to interested in it at the time.  ive got no idea when i'll be out that way again, ive got a truck to pick up from the guy but i cant do that untill spring.  i know it isnt going anywhere so i think i'll snap it up next time i'm out that way.

Are the blocks the same or similar enough to the light truck/pass car blocks?
So could a guy use aftermarket RB heads and other parts on the industrial 413 block?

Some of those trucks had 413s without the industrial heads and some of the industrial head motors had 6 bolt       flanges.  Either way, a 70s casting date 413 block was cast with 440 water jackets, meaning that you can bore them to standard bore 426 or 440 and still have plenty of cylinder wall thickness.  Those ind. 413 blocks also have the extra "cold weather" webbing on the outside of the cylinders.  And if it has the 6 bolt flange      , it'll be forged and can be used with whatever trans you want.  You never know what you're going to get with one of those industrial 413s until you pull it.

that is exactly what i wanted to hear.  i need this engine...   no replacement for displacement

now that ive thought about it for a while, that big block looked normal, there was nothing funky about the heads or exhaust manifolds or water pump.  i'm definatly going to get it when i pick up the other truck i bought from the guy.i think i'll be taking my bbd 727 to the tranny shop and have em go through it and swap in a tailshaft so i can run a 208 or 241 tcase behind it....


i think this will be a great motor to have in a mild 4x4
