can you build your custom engine as cheaply as you can have a crate engine built for you?

this is a question I have been asked so many times I can't even remember how often I've heard it asked and of course as with most things, the answer is
IT DEPENDS ON... :facepalm:



a great many factors ,
(1) like do you have a decent clean, well lighted and adequate place to work?

(2)do you have a wide assortment of the required tools?

(3)do you have the skills & knowledge and experience,

required to even assemble the engine if you have the parts in front of you!

(4) do you even have the knowledge to list the parts and required machine work?

(5) do you have a local machine shop that can do the work correctly?

(6) can you afford to take the time and effort to collect the required tools and components you'll need?

(7) can you buy a readily available commercial or perhaps a custom made short block,
and just add the required components to reach your goal?

(8) are you willing to do the required research to list the best parts,
or at least the most easily available parts that match your
intended goal?
(and that will fit and function correctly if assembled correctly?

(9) be realistic, your wallet and your skill level DO matter,
you probably don't realistically need to build an 800 hp engine in your daily driver transportation

(10) be aware there are people that KNOW a whole lot more about ,
correctly selecting and correctly
machining engine components than you OR I do,even if I've been doing it for 60 years ,
or damn near anyone else ,
(everyone's got some knowledge and skills, but no one knows everything)

so do the required research and ask questions, CROSS CHECK AND VERIFY
and take the time and effort to find a good skilled machine shop to work with,

never NEVER ASSUME ! ASK FOR REFERENCES, TALK TO SEVERAL KNOWLEDGEABLE PEOPLE!
just open your wallet and bend over , as there is always someone willing empty your checking account,
without doing what they promist in the time frame they promised!



now you have to start some place,

and that generally will be in doing the research into what engine components match your goal,
and time spent in research and the purchase of several manuals and books and video's etc.
and talking to a decent machine shop,
can save you a great deal of otherwise wasted money!
what the cost of those
components are and if they are available, and I can assure you that most of the articles in magazines or info on engine builds posted on the internet skip over and ignore a great many components and much of the machine work, time and accurate measurements that will be required.

you'll need to start with the basics, a long list of components, and a check list to list the components you'll need, and
you'll obviously need at least a decent engine stand to do the assembly process,
and you'll want to buy or borrow an engine crane, or have several husky friends handy,
to put the basic block up on and lift the finished engine off that engine stand,

as usually Ill post a bunch of related links and yeah, skipping reading the sub links will as
usual be a big mistake!
yeah as usually its going to seem like and endless bottomless rabbit hole :facepalm: :like: :giggle:

and yeah it helps a great deal if you have
reference material (books videos and spread sheets)

You'll need a few basic tools if your going to proceed

so down the bottomless rabbit hole you go... kicking and screaming in terror...
or is that just your wallet and bank balance I hear? :like: :giggle:
links...and yes you do need to read through the links AND SUB LINKS:swearing:

IN MOST CASES IF YOU TAKE THE TIME AND EFFORT TO START A SPREADSHEET, LISTING EVERY PART,
YOULL NEED DOWN TO EVERY BOLT AND GASKET, AND ALL THE MACHINE WORK COSTS,
AND THE TOOLS YOU'LL NEED,

A CRATE ENGINES AN AMAZING VALUE
SIMPLY BECAUSE THE MAJOR CRATE ENGINE SUPPLIERS BUY ENOUGH PARTS,

TO GET A SIGNIFICANT DISCOUNT THAT YOU CAN'T GET WHEN YOU PURCHASE PARTS,
AND IN MANY CASES THEY HAVE THE EXPERTISE TO MAKE LESS MISTAKES THAN YOU MIGHT
(OBVIOUSLY DO NOT BUY THE CHEAPEST ENGINE YOU FIND LISTED ON EBAY)
THAT'S JUST ASKING TO BE FINANCIALLY CHEATED, :swearing: :facepalm:

AND you'll, surely WIND UP WITH A MIS-MATCHED COLLECTION OF CHEAP JUNK PARTS
the truth here is that most people buy and assemble mis-matched parts over a long period of time and don't build the best engine they might have eventually built, given the acquired knowledge they eventually gain through trial and error,

nor do they assemble the best collection of components the money spent could have purchased.
remember technology advances at a rapid rate and what was cutting edge technology a couple years ago,

is rarely the best potential combo of components or most effective list of parts per dollar spent now!







for most guys you might be better off buying a crate engine from a nationally known and respected engine builder
but most of us don't have thousands of dollars we can piss away on THE PURCHASE OF A DREAM ENGINE, ALL AT ONE TIME!
