New build ran but now wont run.

Cam is a comp cams XE274.

I thought I had a signature and only I couldn't see it.
It is there now. Maybe that info will help.

I do the same thing with lining damper up with 0º on the pointer, then line up #1 on the rotor/cap relation. Some find #1 compression, set the damper mark to whatever they want their initial advance to be (i.e. say you want 15º initial, usually a reasonable amount for a street SBC), then line up #1 on cap/rotor. This insures almost 100% that initial timing is where you want. The only thing you need to cap off when setting timing is whatever port the advance canister hose goes to on the carb (the fitting on the carb itself), capping the advance canister fitting itself will do nothing.

On a parts note, I had an ACCEL Super Coil:

This ran fine on the 305 in the Malibu before I pulled it for the 350 I built. Put everything back together and it wouldn't fire. Put a stock coil in and it fired on the first cylinder. If you have another coil laying around give it a shot

All good advice thanks Doober.

I dont have a spare coil around but may have a neighbor who does.
This car came as a rolling chassis with no motor or transmission.
Everything else was bought new except for the transmission core and block.

Thanks everyone the car started and ran tonight.
I replaced the bushing in the coil, the ignition module wires were a little loose on one side, changed the plugs and pinched the fuel line.
Once it was running I took the pinch off the fuel and kept it going.

Tried to set the timing but it wasn't working how I expected.
I set the base timing to 10* and total timing was at around 20*.
I got the total up to about 34* but decided to stop and think this over before I went further.
I'm guessing with the light springs I was getting advance at idle.

I will give myself a refresher on setting timing and go at it again on the weekend.

I wouldn't think you're getting advance from the weights at idle, unless you only have 1 light spring installed, and nothing on the other. Was the 20º with the rpms up, or with the vacuum line connected? Stock vacuum canisters can add quite a bit of timing.

Hi, the springs are very light.
I actually stretched a set by accident putting them on and had to buy a second set.
I think the idle may have been a bit high as well.
3000rpms with the 20*
Vacuum disconnected and plugged.
No vacuum canister.
Line straight from carb to distributor when connected but it wasn't connected.
