on a 350 chev. motor, you are installing a timing chain, what cylinder is at TDC when the camshaft and crankshaft sprockets are dot to dot ?

Number 1 cylinder is at top dead center.
If the cam dot is on the very top you have number 6 cylinder at top dead cylinder.

TDC= THE POINT AT WHICH THE PISTON REACHES THE TOP OF ITS TRAVEL ON THE COMPRESSION STROKE
hey guys, need some more votes, i know everybody has a opinion about this. lost a bet on it myself. :D
need some votes. i bet its something you all have taken for granted all these years.:D
It would be nice to have a disassembled engine laying around to check, but I only have a foam mock up engine so that's no help.
My guess is #3.
I say that because the way the timing marks are lined up in your post, the crank is one full turn from #1TDC. (Before you flame me here it's been no less than 25 years since my last engine build so I'm not possitive the crank is one turn off, but I think it is.). It takes 2 turns of the crank for all 8 cylinders to hit TDC.
On a Chevy V-8 the fourth cylinder to fire (1 crank rotation from #1TDC) is #3.
So yes, I will say #3 ................ Final answer.
I thought about this for awhile and thought i should come back and clarify when I say TDC I am Referring to "Both valves closed" TDC.
Or maybe sumbudie put one of doz' special grind cams in there & changed the firin' order. HEHEHE
no i put a ford cam in a chev. and screwed it all up.:LOL: :LOL:
What d' ya' want fer' Christmas???
all i wont for xmas is my 2 front teeth.:whacked: :LOL: :LOL:
i have no idea where that came from. i dont do "html" you and pro are the experts with that.:DQuote:

Where did they bury ''Jimmy''?
:confused:
well i dont know cause i have never timed a engine but i would think one but i would like to find out
did they check your yard?:LOL: :LOL:Quote:

when the timing marks are in alignment and closest together, the # 6 cylinder is at TDC. to obtain TDC for #1 cylinder, rotate the crankshaft one full revolution, this will move the camshaft sprocket timing mark to the top, #1 cylinder will be at TDC.
as i thought and a lot of other people to according to this poll that when the timing marks(on a 350 chev.) was dot to dot that was #1 cylinder tdc, but its #6. no big deal, just something to think about, might have a need to know one of these days.
:D **) **)
Er?? Wasn't that book meant to be used for keeping coffee cup rings off da work bench?? :LOL:
this might not be the best place in the world for someone to get there timing info. I always check for tdc by blowing my finger off anyway, so i never used the dot to dot for anything other than a reference point to time the cam. but you could leave the dots there and put the dist in on #6 and it would be ok. most people thinks the rotor button has to be pointed a certain way in the cap, but it dont. i always get #1 comp. up and then put the rotor button where i wont it to be , not where the book tells me to, but the next guy that pull the wires off and dont know that might have a hard time getting it back in time. like you said streets, it don't matter at all what cylinder ya time the engine on.. as long as the plug wires are in the same firin' order sequence, and i say it dont matter where you put #1 in the cap as long as the plug wires are in the right firin' order sequence. :cool: :D
i just wanna know if i install a edelbrock performer plus cam and new cloyes timing gear set and line up the dots without a degree wheel should the cam be in correct time?and should it run good if everythig else is right?
yes the motor will run.
run good?or just run?
Son, I know you're hell-bent-for-leather for someone to tell you that the motor will run great without degreeing it and being able to dial it in and optimize your combination....it might....and it might not.
Millions of motors have been assembled without degreeing the cam and changing the timing based on knowing where the timing is, but did they all run great, or did they just "run"?
