Just wondering what time you shift at for the et you run. How long does your car sit in second gear? And at what rpm does that occur. What is too early? Obviously if it ran out of gear or fell on its face....If it sits in 2nd gear for awhile does heat become a factor in later rounds? Btw, carb works great!

4.40s to 4.80s between a few cars. Normally shift at 2.00 to 2.10 on faster cars an up to 2.30 on the slower cars
The rpm is normally around 7600 to 7800 at the shift. I have left in high gear in these same cars going 5.10 to 5.40 and heat doesn't seem to bother in too much.

I don't shift on time but I do leave in high and have found it pretty easy to manage the transmission temperature.

Torque converter plays a role in this. On our 4.70/7.40 dragsters we shift between 1.75 and 2.00 seconds depending on the converter in the car. That’s at about 74-7500 rpm.

Thats why i ask. Old setup was 1.85 out for 7000rpm, new motor same converter 1.25 equals 7000 but its pretty deadly.... kinda like a high gear car, if people ask im telling them thats why its so slow
