how to asemble an engine basics on video


heres three of the less expensive CDs that are well worth getting, ESPECIALLY the last two!
they can easily save a new guy to the hobby a great deal of time and money and screw ups matching parts
the top one is a cam sellection program, I have got to say that its a good starting point and seldom makes bad suggestions, take the durration and lift and LCA info and buy the cam for your combo from YOUR FAVORITE MANUFACTURER AFTER TALKING TO THEM ABOUT YOUR COMBO...but the software prediction gets you into the ballpark, and if yout thinking youll be useing a siggnificantly wilder cam your probably looking to screw up!

for the more advanced guys

while its very complete and a really good source of instruction especially for guys how have built a limited number of engines it doesn,t get into alot of the finer points like how to hone,the cylinders correctly, what grits to use,how to gap rings correctly for varied applications, how to check most of the clearances, how to set up the oil returns and windage screen, how to dial in a cam, and dozens of other important factors, that make the differance between a good or a great engine

the assembly check list

--------------------------------------------------------------------------------

be sure you check clearances carefully, a mistake can and will damage the engine, DON,T GUESS<KNOW WHAT THE CLEARANCES ARE, ESPECIALLY SPRING BIND,VALVE TO PISTON,ROCKER TO ROCKER STUD, and retainer to valve guide clearances I still use the strips of modeling clay about 1" square and .2" (two tenths thick) but one thing everyone forgot to mention so far is that you need to spray the piston and valve and clay strips with WD-40 to ensure the clay does not stick to any parts, otherwise the clay will tend to stick to the valve and piston allowing them to push the clay between them durring the compression of its surface by the valve (exactly what its there for) and PULL ON THE SURFACE of the clay as the valve moves away durring seperation (because the clay tends to stick ever so slightly as the parts pull away from each other if you don,t)which tends to give a false slightly greater than correct clearance measurement
most people tend to tell me Im wrong about that untill they try it both ways yeah the differance is usually minor but five to 10 thousands differance is not rare if the parts are clean and dry versus sprayed with an oil mist first check to make sure that you are measureing correctly, many times the valve actual has more clearance in the flycut clearance notches,or only the very edge of the valves head and the edge of the notch are close and very minor cutting with a tool fitted in a valve guide will clear the problem and the valve has more clearance than measurements taken from the pistons upper surfaces, and that the head gasket thickness and valve train geometry are correct,
check if changing the cam retard/advance or installed possition can be changed to increase the clearance to 0.100 minimum on both the intake and exhaust valves (MOST LIKELY TO WORK WITH THE LEAST PROBLEMS)

add a thicker head gasket? ( BUT THAT TENDS TO RUIN QUENCH AND DOES NOT TEND TO BE A GREAT CHOICE ON MOST ENGINES)

look over the isky site they and MANY OTHER HOD ROD TOOL SUPPLY SHOPS SELL TOOLS THAT APPEAR TO BE EXTRA LONG STEM VALVES WITH CUTTERS ATTACHED TO FIX THAT PROBLEM
http://www.iskycams.com/pdfcatalog/PAGE17.pdf

heres a few things that should always be checked on an engine build

heads
are the pushrods perfectly strait?
do the pushrods flow oil?
rocker studs/guides torqued correctly?
do the head bolts have washers under the bolt heads? are they the correct length for the cylinder heads in use?
have the heads been pocket ported?
combustion chambers unshrouded?
intake ports gasket matched"
are the valve guides cut to the correct length?
are the heads pocket ported?
is the retainer to valve guide clearance correct?
are the valve guide oil seals installed?
is there valve spring seats installed?
inner damper springs installed?
spring bind height checked? (to exceed max valve lift by .050 min.)
oil return holes cleaned of casting flash?
were steam holes in heads necessary?
were the spark plug threads of a installed spark plug extending into the combustion chamber?
rocker slot to rocker stud clearances ?
retainer to valve guide clearances?
spring bind height checked for the correct spring pressure?
valve lash/preload ?
are the valve springs the correct tension,height?dia.
keeper the correct angle? style? size?
valve seats the correct angles?
valves back cut?
valves the correct length, stemsthe correct diam.
strait?
rockers the correct ratio?
were the valve to valve guide clearances checked?
were the heads milled?
did the head gasket overlap the bore?
what are your valve train clearances?
is the rocker arm geometry correct!
chambers CC,ed
port work..(some steps optional)

(1) open throat to 85%-90% of valve size
(2)cut a 4 angle seat with 45 degree angle .065-.075 wide where the valve seats and about .100 at 60 degrees below and a .030 wide 30 degree cut above and a 20 degree cut above that rolled and blended into the combustion chamber
(3)blend the spark plug boss slightly and lay back the combustion chamber walls near the valves
(4)narrow but dont shorten the valve guide
(5) open and straiten and blend the upper two port corner edges along the port roof
(6) gasket match to/with intake and raise the port roof slightly
(7) back cut valves at 30 degrees
(8) polish valve face and round outer edges slightly
(9)polish combustion chamber surface and blend edges slightly
(10) remove and smooth away all casting flash , keep the floor of the port slightly rough but the roof and walls smoothed but not polished.
(11) use a head gasket to see the max you can open the combustion chamber walls
(12) blend but don,t grind away the short side radias

GV, the book/dvd (http://www.themotorbookstore.com/resmchstvi.html) mentions exactly this fact.

I need a CD with several million bucks in it.

OH, sorry, I thought you meant "Certificate of Deposit", NOT "Compact Disk".

Too bad the really useful factory development programs are not available to the public, almost all of them are really, REALLY GOOD.
