427 from a C-60

Are the 427's in big dump trucks diffrent from regular 427's? A friend of mine found one and wants to build it for his 77 4x4 but a couple people told him it wont bolt up to the tranny....Anybody know?
Thanks,
Mike

It will bolt to the tranny, but it is different than other big blocks. It is a tall deck engine, and there are no commonly available performance parts, like intakes. The heads are so called peanut port design, good for torque, and not much else. Of course if you where building an all out performance engine with many custom parts, it would probably be a good engine to go with. Would also make a pretty good low RPM towing engine.

Tall deck big blocks make great tork motors but have no hi rpm potential as to no hot rod stuff.They do last a long time because tall decks are heavy duty and have an extra ring on each piston

Re: 427 from a C-60

First make sure it is a 427, the 366 is much more common. If it is a 366 walk away, small bore and can't be bored out enough to be worth anything.
Use a 454 crank and you get a tall deck 454 and you can use long rods. The engine in stock form is a good truck engine. Like stated the heads are small ported for economy and low end torque. Pass car heads do bolt right on. After market intakes are available, and many allow the use of a normal v8 distributer. Spacer plates are out there too, this will allow you to use a standard deck intake.
Use a 4.25 stroke crank and get up around 496 cubes.
That engine will have a steel crank and four bolt block in it's stock form. A lighter set of pistons will help it rev better.

I do know intakes are available, but they are single plane race type manifolds, not something you would want to use on a 4X4. Spacers are an option, but you are still looking at a lot of custom parts for a mild performance buildup. You would be better off finding a lowdeck engine.

So even the block itself is diffrent, cant swap on heads and intake from a normal 427?

Yes, the block is .400 taller. Heads will interchange, but not the intake without spacers. Intake, distributer, pushrods differ between engines.

And the distributer is longer, but you can get an adjustable mount MSD distributer.
