I,m just curious, how many guys print out a "WISH LIST" of parts, and then do the research and arrange the list to make all the parts compatible,
so all the parts match the intended goal, then once they are sure of the parts list, they proceed in acquiring the parts?
buying an engine stand to work with and assembling the engine the way you want it, and putting the headers and exhaust on the car,swapping to the rear differential and transmission stall speed you'll need having done the math well before you were forced to upgrade the parts simply because you found you can hardly drive the car with mis- matched components, if you tried to drive it that way, before you drop in the new engine!
that's the (AT LEAST TO MY WAY OF THINKING) the more logical way you proceed as constantly pulling an existing engine to make mods, like changing the cam, swapping to roller rockers and maybe new pushrods, swapping to new heads, higher compression pistons , adding the better new heads, swapping to a higher capacity baffled oil pan, adding an oil cooler to that oil pan,upgrading the timing chain, swapping to a better oil pan, water pump, adding a windage screen, swapping to a new ignition, in random steps as you locate the parts and your wallet allows the upgrads seems like a whole lot more work,
honestly I have talked with dozens of guys over 5 decades and the majority bought a BBC powered car, maybe it was O.E.M. stock or someones previously modified car, but very few have built the engine and assembled it prior or completed the engine the way they wanted it to be before pulling the original engine out and installing the engine they built!
trust me when I strongly suggest that after doing it both ways, the simple swap to a pre-prepared engine in a car with a match drive train and exhaust system is MUCH EASIER and more fun to drive and has FAR FEWER POTENTIAL PROBLEMS
the link and sub links will be helpful

I recently had a long conversation with a guy who had started to collect the parts he thought he would require,
to build the engine he wanted to build for his "DREAM ENGINE PROJECT "
yet against the odds the more persistent members seem to get the pet project done at least to some extent over time!
now lets look at facts! yeah I know 99.9% of us don't have the bank balance required to build our "DREAM ENGINE BUILD"
but that's no reason you can't at least get out a large legal pad and write down what you would like to build, an get a better mental grip on the time and potential cost...

for many years Ive used an engine crane in the shop to pull engines, and it became very obvious that some mods to the system were darn near MANDATORY, ID start by pointing out the 2 ton rated engine cranes tend to be FAR more solidly built and have significantly longer reach and more stable bases , than some of the low priced import crap.
heres an area you really do tend to get what you pay for to some extent.
ID strongly suggest you rent or purchase a high quality engine crane and a engine tilter, as at some point your going to be at risk if the cheap crane tips or fails...

I recently had a discussion with one of the local guys concerning what heads and rotating assembly he should buy now that he recently purchased a tall deck (10.2") big block chevy block.
he has a perfectly good 427 forged crank (3.76" stroke) but hes seriously thinking of buying a (4.25" stroke) forged crank.
the DART blocks available have got a 4.6" bore.
ok simple math, displacement= bore diam. x bore diam. x 8(cylinders)x stroke x .7854
lets assume these are max effort race engines built with 13:1 compression requiring E85 or race octane fuel, and yeah if your...

has anyone seen actual plans for fabricating this particular work bench?
obviously you can make reasonable guesses at the dimensions and build something very similar
I think you can assume the (I-beams and rectangular leg dimensions will be standard materials)
maybe the tops 48" x 96" and the bench is about 36" tall floor to surface?
or it might be a bit smaller?...

HOW FAR CAN YOU BORE A BLOCK?
before you begin to have a engine block bored more than about .030 over size its a good idea to have the blocks bore walls sonic tested
Have your machinist sonic check the block before you bore it.
calculate the remaining bore wall thickness, and if its not thick enough for safe use don,t bother
, bore walls are rarely if ever uniform in thickness from top to bottom or side to side, or concentric with the bore center line. and the STOCK O.E.M. production sbc block is well known to be fairly weak...

This guide is intended to help you sort out the more major differences among Big Block Chevrolet engines produced since 1958. Chevrolet has designed and produced several different "big block" engine families. Within each family, there can be evolutionary changes, and special parts designed for competition use which may not be directly interchangeable with the regular production items.

I finished grinding my block for 383 stroker assembly a couple of weeks ago. I found a tip to help cut down on metal dust particles. Take a magnet any type, and put it in a zip lock bag, then place the bag as close as you can to the area your grinding. I put mine in the direction of the flow from the grinder. When you get thru grinding remove the bag from area and then slip the magnet out, this will catch most of dust and leave you with a clean magnet afterwords.
Ok youve just installed your crankshaft in the engine block, with new main bearings and everything's well coated with assembly lube,and oil, and youve torqued down the main caps to spec. in at least three stages, and then gone back and rechecked the studs or bolts per the manufacturers instructions, but you have yet to install the pistons and rods, OK, its time to check the rotational resistance at the first stage, while your assembling the engine on the engine stand.

look closely at the connecting rods one edge of the main bearing are is beveled noticeably more than the other that beveled side faces away from the rod its paired with because it matches the slight radiased bevel of the crank journal
many builder class pistons are designed to go in, in either orientation ,and have both the valve notches and piston pin offset that are identical but most performance pistons have a dot or an F stamped on the crown indicating the side facing the front of the engine, naturally the rod big end bevels face the crank counter weights on each pair and the...

always think every step you take in any performance engine build through,

without asking detailed questions , and documenting as much as you can in writing,
and having a well thought through plan, parts list and time frame,
and yes get receipts with detailed explanations due dates and prices,
and yes you'll need a skilled and trust worthy machinist!
