put a .060 over 455 in my boat. everything came off of my old motor that possibly spun a bearing, nothing too bad.....
here is the deal...i can't get it to fire. i have fuel, air and spark. timing is spot on. wtf. going to pull a allnight so aquaholic cant talk sh*t when i kick his a**.
anyone?
-
180 out?
-
Does it even sound like it is trying to start?
Double check all the basics, wiring connections, grounds, Ignition wiring, How did you verify timing?
Just throwing things out there, maybe it will help you remember something.

yeah its not coming thru the carb... its not 180 out. sounds like it wants to fire.. flooded maybe. running dual 850s. grounds are good, all wires check good. im baffled, also has 2 friends over to pick their brain.....

Need more info, how long has the motor been sitting? Sometimes (not too often) if a new motor sits for a long time, the cylinders dry up and there is not enough compression to light off (also could be fuel washed), try a little oil down the carb for that, otherwise, the spark has to be at the right spot, does it pop back through the carb? Also, how strong is the spark, may not be getting full spark to the plug, especially if an electronic dealio....
Valve lash could also be too tight, not making compression, who did the cam timing?, that could be wrong too, boy the more I think about it, these things are a pain in the ass...LOL ;D

dual 850s???

motor sat for a year with oil in it. i put oil in all cylinders prior to starting( dry start bad). everything is turning, just wont light off. i feel its flooded. im going to the river tomorrow and i think im puttin in an allnighter. it is a new motor though..... need to do a cam break in..

Time for some starting fluid, plugs could be oil fouled too...

it likes the gas... ha

thanks guys. my neighbor just came over. not about the motor, but the lights shining in his window... calling it quit. will fix on the river.. thanks all, justin

I run two 1050's

plugs are good. weird huh.
-
first off, the river is not the place to do a cam break in. Next, take the gasoline rainbirds off, put a single four barrel on it for the break in. Recheck everything The last thing you want to be doing is cranking the engine without firing and getting it oiled, you WILL lose that cam.

X2, the air conditioner in my house only moves 1200 CFM... :screwy:

that strange gasoline smell during your next oil change is telling you something...
-
I rarely even get into the secondaries, if I do it's just a quick stab, couple seconds, boost is around 6-9 at that point.

HD, excuse me for pointing out the obvious, but your huffed BBC is a just a little different than a new .060 455...heehe

Take off a rocker cover. If they let the motor sit, they may have planned on that and backed off the rockers to save the springs. Sounds obvious, but maybe. Second, double and triple check on the 180 degree out thing. (Easy to do, #1 comes to TDC Twice in a cycle, once for compression and once for exhaust). Been there and done that MANY times., not trying to make you feel like an idiot. We've all done it, and recently.
Find TRUE tdc then set initial timing to 10 degrees or so BTDC. Should fire.
If that's ok, Compression check it. obviously it's cranking.
If all that checks and double checks ok, Follow Terry's advice, add an 8-71, two 1050 dominators, get an Exxon Credit card.......... ;D

I know, I'm just bored and feel like typing.........about ANYTHING

we need to get this fixed. if justin is a no show this weekend aquaholic will be the champ 2 yrs in a row. ;D
but no one wants to win that way.
there is something stupid we are missing. engines are simple creatures and if it has air fuel and spark it will run. we just need to get those three things to dance together

What type dist? points or elec.
Do you have 12 volts at the ignition box, or coil? If the input volts are down so is the output.
Pull a plug wire, stick your finger in it. Have someone crank it over, if you piss yourself spark is good ;D
Did you try starting fluid? What effect?
If it's popping up the intake I'm betting the timing is 180 out too or it's not getting the fuel you think it is. (not likely with 2x4's) Do you have a vac gauge? If so what's it reading while you crank?
Oh, and don't forget it's not air, fuel, spark bang.
It's air, fuel, compression, spark, bang 8)
Days like yours is why Ford put the dist. up front, easier to trouble shoot ::)
Good luck, and yea, it could happen to a ford..... just not likely ;D

Big ass vacume leak?
-
Did you pull a plug to see if it's fuel soaked? If it is why not unhook one of the carbs, go to wide open throttle and give it a shot of starting fluid.
Did you ever consider a 460 ::)
