Is it best to degree a cam before or after you advance the crank 4 degrees?

There is no such procedure to 'degree' a cam. You don't want to advance the crank without also advancing the cam or it won't run very well at higher rpm.

How many degree crank shft turn in every storke?
With a four stroke engine each stroke is 180 degrees.
Is the Triumph 865cc parallel twin 180 or 360 degree crank?
It's a 360 or a 270 degree crank depending on which model of the twins you look at.
What is the transmission angle?
Angle between coupler link and output link for a given crank angle is called transmission angle, it is maximum when crank angle is 180 degree and minimum when crank angle is 0 degree
What mark is tdc on the crank pulley on a 2003 Nissan truck 3.3L?
If you were holding the pulley in your hand the degree marks would be from left to right 1st mark being 0 degrees or TDC then 2nd mark being 5 degrees and so on
Can timing in 1996 2.2 liter Pontiac sunfire be 180 degrees out?
1996 pontiac sunfire 2.2 crank was moved but cam was not could the timing get out 180 degrees before i put it back together
How many degrees of camshaft rotation are needed for a piston to travel from tdc to BDC and return to tdc?
A camshaft would travel 180 deg for every 360 that the crank turns.
Need the firing order for a 1964 Corvette stingray?
The firing order of the LS1 is 1-8-7-2-6-5-4-3.This is different than even the GENII engines.Soyou get an exhaust cycle something like this: LRLLRLRR (this is pulledfrom two full cycles "LRLRR'LRLLRLRR'LRL") note the double pulses.Theonly way for GM to get this firing order and keep the engine balancedwas to implement a 360 degree crank. The 360 degree crank only impliesthat the throw angles of the crank occur in the full 360 degrees (of acircle). This is different than a 180 degree crank where the throwsoccur only at the top (0 degrees) and bottom (180 degrees) of thecrank. A 90 degree crank will have throws occurring every 90 degrees(like the major points of a compass).Sowhat does this all mean? That a 360 degree crank will have multiplepistons travelling in the same direction at the same time. This causessome interesting balance issues, but by manipulating the firing orderyou can take care of the major problems. To contrast the 180 degreecrank will have pistons moving in opposite directions at the same time.This makes the engine act like it has two cylinders in an engine casewith 3 other 2 cylinder engines.Soto answer your question, the engine is still a 4 cycle engine (intake,compression, combustion, exhaust). The piston still has to travel upand down twice, requiring 2 strokes (crank revolutions). This means theplugs could be firing any time during those 2 crank revolutions (4 onerevolution and 4 the other) which is what a 360 crank allows. And I'msure the timing is set up so that everything is balanced. That's the bulk of my knowledge on that I'm sure I've made a mistake or two but for the most part it should be pretty accurate.AnswerThe firing order of the LS1 is 1-8-7-2-6-5-4-3.

What are col crank amps?
Amps produced at 0 degrees (F).
What are the types of crankshaft?
2 types of crank shaft are there 1.same plane 2.cross plane crank shaft in cross plane crank shaft cranks are inclined at 90 degree and in same plane crank shaft cranks are in same plane. thnk u
What is a bellcrank?
A bellcrank is a variety of crank which changes motion through an angle, typically between 90 and 180 degrees.
How much degrees is your piston, head and crank?
um do you have a test you aks a lot of Qwstshon that would be on a noun test
What does 15 degrees mean?
15 degrees is the amount of crankshaft rotation. All rotating internal engine parts (cam shaft, crank shaft) turn 360 degrees, that's one full revolution of the engine. The use of degrees is for ignition timing. ie 8 degrees btdc (before top dead center) That number depends on you engine size and can be found on a sticker either on the fan shroud or the front of the hood near the latch.
