Well, I have the other thread about converter slip because I am was not so happy about how the new 461 with High Ports was doing. Its a 11.5 -1 CR engine and we all know that is on the high side for a pump gas engine. Right now I do mix 1/2 gal 112 to 4 1/2 gal 91 to get 93 octane. Getting it to run on 92 all gas-gasoline is the goal but not there yet.
Being a 11.5-1 engine I have been very careful with the tune. The thing with High Ports was they are supposed to like the timing in the 28-32 deg range. Or so I thought. Started out breaking it in at 28-29 deg and then 32 deg. It 60 footed great, but MPH sucked.
I had terrible converter slip or so I thought, sent my 9" PTC back to get loosened a little. Got it back and 60 foot went from 1.39 down to 1.46. I was p!$$ed. So I thought I would try 34 deg, timing light was acting weird so I put the distributor to a mark I had on the firewall for 36 deg, where the old 9-1 HO engine like to be.
This was after my time runs so it was on my first elimination run. What the heck, I was not happy anyway. The car took off, not a perfect run either because I was on the brakes hard because I was so far out in front of the guy. I made 3 passes at 36 deg, none of them were really good run. Had a spin on the line and fan belt was off my last run. Engine made a weird nose right before the shifts. Maybe the voltage was down ?
But, the car ran .80 faster than it did at 32 deg. best ever was the last 10.34 run popping. Did a 6.43 in the 1/8 too. 103 MPH.
Went from a 116 to 126 MPH. All from 4 deg timing ? No real tuning, playing with shift points, taking off at higher RPM and have not tried the 1050 I had worked for this engine.
Well, any a lot happier now. Low, low 10s are within reach and a high 9 is not out of the question either.
Now, I really wonder what the TCI 8" would do with the engine running like this ?

So, what are other High Port guys running for timing ? The 28-32 deg just got thrown out the window as far as I am concerned. Wondering if 37 or more deg would get me anything but I should raise the octane if I try that. I will leave it alone for the next race, Wally race so I just want to try and win.
But the last race I think I will try the 1050, maybe the old 850 or the 8" TCI.
