Re: Odd ignition problem.

Swapping the wires between the distributor and the MSD box does make a big difference on the distributor phasing.
One of the combinations puts the rotor between distributor cap terminals and can cause crossfiring under load.

Did you check the timing with a timing light?

Re: A question about aftermarket TBI?

Did you adjust the idle mixture screws for maximum intake manifold vacuum at idle?

That particular camshaft will require a minimum initial ignition timing of at least 16 degrees BTDC checked with the vacuum advance disconnected.
What did you set the timing at?

Very Good Info. Thanks
The LS rod adds .050" rod clearance which isn't that much IMO and the article states that a lot of side clearance can be a problem in high rpm race engines which the 300 six is not.
I'm thinking that LS rod side clearance control is not a concern in the 300 six.

Yes but the goal is to move away from a manifold that has a common log to all six cylinders.
The exhaust manifold pressure is at least twice the intake manifold pressure and the engine hits wall as you try to make high rpm power.
