400 truck engine any good?

[javakmcharger68]

Two questions on the 400. Wondering if there are any difference with the car 400 heads & the heads off of 400 truck engine? Plus, will a 400 oil pan fit a 383?

the 400 pick up engines have the same heads , motorhome engines sometimes use different heads
the 400 & 383 pans are interchangable

So what is the big difference from a 400 car engine, comparing it to a 400 truck engine???

nothing as far as i am concerned.  maybe a different cam grind (thats a guess).  well of course different oil pans hehe.

Some Hp 400's with standard transmission had a forged crank, otherwise they were cast crank engines.
