410 Compression Test and tuning.

Did it stop advancing at 2800 or did you just pick that number?

imo, 15* is not enough initial for that cam to get it to clean up. That's stock cam initial timing territory.

Hey Rob
It did stop advancing up to 3000 rpm(36 solid). More concerned with getting a base tune to rule out bad tune causing overheat gets to 210 pretty quick.
Initial is at 15 and we left the vacuum advance disconnected for are test drive!
I agree initial is low my teen with a xe275hl is at 22 initial and 36 at 2800.
We had to let her cool from timing, to carb float adjustment ,to air fuel adjustments.
Did not actually get to 240 on highway that happened at a long light.
Running 230 on the highway home.(short 2-3 mile jog after long light)
He is running a spectre 22 inch 2 row radiator and needs more radiator....
Sweet car and is solid....
Would appreciate any advice on tuning but would you agreed we need more radiator First!
