Does anybody know how much power to expect out of a 72 413? I was told when I bought it I was told it was a 440, but i discovered it was a 413. It has 31,xxx mi. and came out of a motorhome, and I plan to put it in a 1979 volare. Thank you.

I am a fan of the 413 .. but will be the first to admit that it is a Lo-Po motor. Weak compression is the main problem. It CAN be made usable for your application BUT you will need a set of VERY small chambered heads AND a cam change.

Dont expect much, about the same as a stock 360 4 bl..
The 413 Industrial engine is a top notch engine, with plenty of low end power,and ability to last forever.
but it is really heavy, the heads are totally wrong for any car and the waterpump wont work..etc..
Did I mention Volares are pretty heavy already with transverse suspension?

They are rated at something like 220 hp and 400 tq. Likely pretty flat tq. Good car heads, better cam, and headers might get it up to 300 with increased torque.

A set of 383 low compression pistons would up it to 426 ci,and likely raise the compression a fair amount. You might even have to mill the top of the piston some, or use a very thick head gasket/open chamber head. Could be pushing 400 plus hp with ease.

Thanks for the replys, this is my first BB. Are the heads for a 413 different than a 440? I thought they were tbe same.

Some 413s from the early 60-63 C-Bodies were rated at 340 horse; weren't they?

So can I expect any decent performance outta this in stock form? I was hoping for a street car with a small amout off giggle factor. Or are we talkin boat anchor here?

STOCK FORM ? ... using the heads that are on it now ? ... not so much.

PLUS ...I don't think that the exh mans will work in a car application.

Correction ... the truck/motorhome 413 was rated at 265 hp. 7.5 to one compression ratio ? ... was a VERY optomistic #. In most cases - with a fat-deck - it was sometimes in the 6.5/6.8 area.

The REV possibilites of this 413 ? ... these dished pistons were NO lite-weights.

So, in stock form, this isn't much better than the orig. 318. Is it?

lol no way you can compare a 318 to a 413
drop it down in the 79 duster drive the crap out of it and when you decide you want some more power and put a 8 3/4 rearend in it we will fig something out and besides your not even sure yet if the motor is a 440 or a 413 lol mine came out of a motor home and is a 440 you just need to bring it home lol

Thanks for the advice everybody, I guess if i have to change a few things, it will be worth it since i only gave 150 for the car body and 300 for the engine, tranny, radiator and driveshaft. I was lookin to make a fun street car on a budget, and I think I still can with this setup.

the manifolds on it will be changed as i and buddy from work have differnt manifolds for it from what i seen of it so far the water pump dont look any differnt then any other big block water pump/housing the motor came factory with a holley carb (still on it) did 413,s come with a holley or was that a 440 thing?
the motor he bought is still in a motor home (100+ miles away) that a guy started gutting for the alum. it dont have the big drum on the back of the tranny he (bryan)was spossed to get it out today and bring it home and as stated before still not 100% sure its a 413 or a 440 (yes its a raised block) he is looking to have some fun on the cheap and he really likes F bodys and so far his investment is $450 with lots of room to grow and plenty of options now go round up all the tools for tomarrow and bring it home lol
