Timing / vacuum

[Brian Safford <hzf9vv@xxxxxxxxx>]

I talked to a tech at Barry grant about tuning my 625 cfm road demon on my
poly 318. I get black smoke whenever I floor it. He asked me three things -
timing at idle, vacuum at idle and cam duration at .050

Timing is 12 degrees btdc,  vacuum was around 14 and my Daytona cam has 218
at 50.

He suggested I switch to a 4-hole spacer rather than the open one I'm
currently using, and also thought I should move the timing to 14 or 15. He
also wondered if I had good hot spark. Not sure how to check that.

I asked about the power valve and he said it probably isn't even opening as
the vacuum would have to drop below 6.5 for that to happen.

I have power steering that uses vacuum as well as a pcv valve - do those use
up too much of the available vacuum?

I don't want to risk damaging my engine - are any of his suggestions
potential problems?

Thanks as always,
Brian Safford
