Initial startup, 67’ 330, help
Hi!
i’ve rebuilt a 330 10.5:1 comp and i am struggling with getting it started.
i’ve given it a slight bit more than 10° of initial timing on the crank at the compression stroke.
dropped in the distributor(HEI) and lined it up with #1 cyl and checked spark by grounding the #1 spark plug and wiggling the distributor then pulled it back slightly.
carb is a 600cfm Edelbrock, it has fuel, spark when grounded outside the cylinder and i am able to achieve some small sputters but not much more. It feels like it cranks a little too slow for some reason as well. Any thoughts are apreciated.

Get someone to crank over the motor or hook up a remote starter and trying turning the distributor at the same time. Did you fill the carb bowl with gas? What starter is in it? Is the battery fully charged?

And you're SURE you don't have the distributor 180 deg out?
As for timing, you can use a timing light when the engine is cranking on the starter. I usually leave the distributor a little loose on initial startup and have to turn it slightly while cranking.
As noted, be sure the carb float bowl is filled. Be sure you battery is fully charged, wire connections all clean and bright, starter in good shape, etc.

poured a good chunk of gas into the carb, it was a new starter when i started the project so it has only been used to crank the engine so far. And yes the battery has been topped of at the start of each session

I found the easiest way to verify TDC on the compression stroke is stuff a something such as a wine cork in the #1 spark plug hole and turn the engine until the cork pops out. There's no uncertainty with this method.
