yes that it is, so looks good.I was just worried, as my calcs had some flaws. Big Grin
Assume all is my fault in just using static timing only to start with but NOT correcting it by ignition light.

Weather got better, so TOMORROW.. Cool
Also as said befor I do not know how a "good" Cleveland should sound.. Smiler
I compared the engine "sound" with my C2 Corvette (327/350HP 1967) with DT Panter it did NOT sound as good. Well the static advance was app. 20! so bad.. will go now for a save and good sounding +/-15 deg. and run a while & measung the advance in total ..then further adjustments.

Keep you posted!

& TX Team US & Europe ..Danke..I do not do Cleveland every other day..

Pround on my Panter

there may still be some concern with yuor timing marks on the balancer and whether the scale is properly located to match the pointer?

you need to confirm #1 TDC even it's not precisely accurate but close enough to tell if the scale is in the right place at all

some aftermarket balancers have multiple scales or they're for a different pointer, it needs to be checked if you haven't
wooow what a Cat!

well today...no rain!
1) #1 is #1 so no mix up
2) TDC is correct and marks on ATI damper are very much correct
3) vacuum tube off distributor un-plugged and tube closed for timing light work
4) at idle app 15 deg. advance fixed, my be a bit less
5) with vacuum tube on, the distributor does add app 15 deg at 3000 rpm. that gives for now max of app 30 deg. Good to go for the next 500km until engine is run in a bit.

Engine sounds perfect now. Did drive app 60 km with max 3400 rpm as all band new. BRUTAL..this pull! Oil pressure good, Temp very good!

Tx again for help!

Matthias and his Panter
My 10.5:1 c.r. 351-C runs best with 28 degrees total advance & 15 degrees initial on a fully warmed up engine. After setting these, I reattach the vac advance and adjust that curve, too. I get over 20 mpg@ a steady 90-100mph w/no pinging.

Most modified Clevelands with closed-chamber heads and some sort of aftermarket cam give best results with 30 degrees or less total ignition advance, due to the extremely efficient combustion chamber. High advance is a SBC setting for their less efficient heads, or for drag racing, not continuous street/highway use with a Cleveland. You'll very likely find this on the dyno during final tune.
yes is amazing what the little tune does. Static was 20 advance unintentionally - I tried to hit 10 deg. and I did not check it ASAP - it was extremly hard to turn the crank in the right position by hand/tool. So Engine did sound terrible..no nocking though rev up to 2500 on first 20 miles! (I have done old Posches and VW engines at my student age, it was easier as much smaller cid and les compression).

René: much more brutal than my C2 67 Corvette Con. (and that C2 is good!), and I tried only up to 3400 rpm..mainly 3rd as need rpm variation to run in..

Bosswrench: top to know, after the team's work on final calculation and fixing my mistakes +/- 10.5 is where I got, yes modern heads (Trickflow), modern cam (Crane). I could sense the smooth running by turning the distributor in (5 deg) and out (20 deg), <15 deg. did sound very smooth - well roller as usual a bit noisier - , I could go higher to 18 was still ok, but turned it back to <15. That goes with your real life experience! And my dynamic advance will take it up to said 30 deg. max. Tx for the experience based info.

Honstly, I got a bit nervous after the very expensive rebuild on my cat's engine that it might not be good. The build was done by a Germany mashine shop, known for US engines with good reputation but the final design and parts and calculations I did mayself based on George's docu and the Book from Tom Monroe..
