My aching 60’ foot

Without knowing additional specifics of your combo, I’d try a few things.

• Increase timing
• Recurve the distributor to bring timing in sooner
• Try different fuel- not knowing what you run, more octane doesn’t mean more power.
• Change jets- assuming it’s Carbureted
• Have someone video the car launching to see if it’s spinning, unloading, twisting etc...

Give Kemp some straight answers and we might get somewhere.



Means your HP isn't changing

When you spin off the line your MPH goes up and if I was having mechanical issues the car wouldn’t be pulling 120 miles an hour for the last 13 years so let’s get back to my original question has anybody ever tried using vacuum advance Was bench racing with a couple of guys after the race yesterday and one of them suggested playing with my valve lash to fool the engine into thinking It has a smaller camshaft and see what happens
And then maybe it’s just the nature of the beast and that’s all I’m gonna get from it

You would have to call me on the phone because it would take forever to type out all the specs on both vehicles

Race car = no vacuum advance.
Street car = use vacuum advance

I don’t have vacuum advance on either car but you have tried this and it does not work or you’re just saying this because that’s the norm and everybody already knows that PM me give me your number and I’ll give you a call

If you believe that it's fine - After 13 years in the seat you would know spin or even looping the tires. If you think about it your converter flashes to 4000 and vac advance does nothing @ wot and centrifugal adv is all in. On both the Sonoma and the Regal the timing is locked out. The Regal is running a stock block 350 (L-82) and 60's at 1.48 to 1.52 depending on if I am running 28 or 29 tall tires

I don’t typically make mention of things unless I’ve done it. Hope you get it figured out.

Race cars don't have vacuum until after the finish line. Vacuum advance does nothing for a race car.

I only have two weekends left and due to a rule change pro cars are allowed to run transmission brakes so I will be changing over
