Educate me on building my block....

the title says it all. well after doing some research on the fate of my engine, if I'm going to build my motor, I'm gonna go the rotating assembly way, rather than the short block, due to $$$, plus what am I gonna do with an stock engine block in my garage??

I've looked at all the rotating assemblys on the market; BBR, MMR, Livernois, JDM and Stage 3 Motorsports. all within the same price range of each other, stage 3 having to be 400 bucks cheaper. from doing extensive research, everyone gives Kudos to Livernois Motorsports due to the quality of the parts. based upon that, I'd def be going with Livernois. I'm just going with the basic forged roating assembly, no stroker kit or the different machined pistons.

now for the questions. someone mentioned that my engine block needs to be machined for the rotating assembly to fit? is this true? also they said I want to invest in the GT500 oil pump, for the stock oil pump doesn't like forged internals. I will also need a new crank pulley to balance out the new forged crank??

any other info is greatly appreciated!

I run the stock oil pump and I'm pushing nearly 600 rwhp. Not sure on the need to swap harmonic balancers.
If you aren't increasing the displacement (i.e. stroker), you can get away with just upgrading the rods & pistons; the stock crank is good to around 600-700hp. Plus, you can save a few bucks if that is an issue. Otherwise, just get the entire assembly.

It won't hurt anything to have a machine shop look at the block.

The oil pump has nothing to do with what internals you are running. Improper balancing will ruin it.

You don't NEED a new balancer, but it won't hurt anything.

Don't forget bearings, studs, bolts, tensioners, chains, heads, oil pan, water pump, gaskets, yada yada ya. Price it all out and you aren't going to be far from the cost of an already assembled block. You can always sell the existing shortblock; someone will take it.
In this day and age it’s completely insane to put your own shortblock together when taking into account how inexpensive it is to just order one up. The price difference between the parts and machining and a built shortblock is so small it’s not worth the time, effort, aggravation, potential problems, need for specialty tools, etc. I can build motors in my sleep and there is no way I would put my own shortblock together. I am much better off spending that time doing what I do for a living and getting paid for it.
Why does everyone always skip the part about what happened to their engine lol ?

+1... I could have purchased a forged and balanced short block for what I paid for the new guts and labor to tear mine open.
I guess it depends on how and where you shop. Strictly speaking in terms of estimates, I'm looking at being at least 2K in the black by gathering all the parts over time. Some are used, some are new, but that's why they call it a budget build. I wish I knew how to put this darn thing together properly though. I'd have enough left over for a blower too! :happydance:

Plus I don't have 5K right now for a block. :so

New and used parts!:happyhapp Pay now or pay later there is no such thing as a budget build. $.02

New parts fail too, but used is such a dirty word. I should have said, "certified pre-owned". :gringreen

Maybe they should rename it to a "small" budget build because that's certainly what I have.
