What is the stall on your converter? The converter alone probably knocked 1/2 sec. off ,right?

No mods for this engine. It's tired. I exaggerated. It is closer to two seconds than two and a half, around 2 1/4. I have the replacement engine on the stand, I have for a couple of years. I just can't figure out how I'm going to feed it. The Crossfire won't do it, and I really would like to keep it a Crossfire. The wheels are turning.

It is a 2600 RPM stall Vigilanti. If I recall correctly the converter was good for six tenths. Well over half of what I've spent on modifications and improvements are in that converter. Without the converter I've spent $500.00 to $600.00 on pieces parts.

RACE ON!!!

Thanks for the info. That's the next thing I'm looking to change on my 87. That should keep me in the 13s all thru the Summer.

Mine only burns a quart of oil every 500 miles.

I take it you don't head too far from home. But I guess an SBC will run on 2 quarts (don't ask me how I know!)

I can't go much past 450 miles on a tankful so I stop and fill the oil and check the gas. It doesn't seem to burn it quite as bad on the cruise control as it does at the drag strip. The farthest *I* have ever driven it, in one stretch, is to Bracket Finals in Tucson and in Sonoma. Both were just about 850 miles, each way.

RACE ON!!!
