Hereof, are 454 engines reliable?

Re: Reliability of 454 I have found them to be very reliable although I haven't had one with more than 45000 miles on it. They do tend to run a bit warm but once you find the "normal" for your unit and keep the coolant clean and properly serviced you should have no trouble.

Additionally, how much does a 454 engine cost? Around here typical bare engines are in the $1000-$1500 range. Just the block is worth $500. A complete running engine (old and tired) can fetch at least $2500 with all the brackets etc.

Similarly, you may ask, how much horsepower is a 454?
