TLowe,,,
So, 3650? I will guess you weigh 200??
I would think an Elky would be lighter than a Malibu?
Is a 292 heavier than a standard SBC 350?
Maybe with the turbo exhaust manifold,turbo,intercooler, plumbing etc.

A 250 is supposed to be 100 LBS lighter than a standard SBC.
Glad that closing the plug gap fixed it.

When is the next rack day to run it again?
