Just installed a new cam in my 360sb and now no start. It will sputter and backfire. I lined up my timing marks correctly on the timing gear. Also im getting oil in my cylinders. Pulled the plugs and everyone had a coat of oil on it. Any insite woiuld be amazing

Oil in the cyls would be a major concern right now...
and all you did was line up the dots doesnt say antyhing...
I have had cams made wrong(factory ones) and they would
hit the pistons if you lined up the dots... I will
assume you checked to see if the dist is 180* out

I do not. Ive been doing some reading and do the timing marks on the cam and crank gears face eachother or point straight up?

they face each other, and that is #6 firing

when they are both at 12 oclock that is #1 firing.

This can confuse most people until they get the hang of it.

check/clean your plugs and check wires ( firing order) and then try moving distributor and check with timing light.

probably nothing wrong with the cam. If it starts it may run rough until all lifters pump up.

Are you using adjustable rockers/pushrods? What cam- hydraulic or solid? Might have the valves set wrong and valves arent closing..

A flat cam isn't generally going to oil up the cylinders and NOT all of them.

I'd be looking at the intake manifold gaskets as a culrpit. You have the locator pins on the valley rails and using silicone, not the cork?

Are you 100% sure it's oil on the plugs and not gas?

I have a couple Mopar Performance chain sets that have the timing marks 2 teeth off. Degreeing the cam is cheap insurance.

If you put a cap and wires on are the wires on the cap in the correct direction?

Pull the #1 spark plug and put your finger or thumb over the hole and have someone bup the starter around a little at a time until the #1 piston starts to blow your finger(or thumb) off the spark plug hole. Stop there and look at the timing mark on the timing tab and the balancer, barely bump the starter to get the balancer timing mark to be close to 10 to 20 degrees before top dead center. Pull the distributor cap off and see whre the rotor is pointing, if it is not pointing close to just before the number #1 spark plug wire fix it by reindexing the distributor or oil pump drive, or both if that is waht it takes BTW, did you replace the timing chain and gear swith a three keyway set? If so which sets of dots did you use? The ones next to the crankshaft itself or the ones on the outer edge of the crank gear

Broke down and just tore into the motor. I think i found my bone head problem. I put my timing mark on the harmonic balance on zero. Then pulled timin cover off. The marks on the two gears were straight up on both. the distributor cap was burnt up. I dont quite know if anything else is burnt up yet.

oil prob was a terrible seal on the valve covers. When i pulled the rest of the plugs they were dry. Kinda freaked out there for a bit sorry fellas.
