I went racing last night and when I turn the car off my car will continue to run. Also, by the time I near the 1/4 mile, my car will die off at wide open throttle. It only dies when I am almost at the 1/4 mile mark. The RPMs will drop down and it feels like I just took my foot off the gas. Would the RPMs stay high if my tranny was slipping though?? Also, I think it is backfiring at the 1/4 mile. At the line, I got a huge backfire out of my carb then the car died... it started right back up. I lowered the fuel pressure to 8psi and the timing is advanced 10 degrees at 600RPM. I also put springs and bushings in my MSD distributor (will this cause it?). Anything will help.

 

if its backfiring out the carb you got a timing problem, it sounds like you may have a fuel delivery problem too, or your getting hot fuel, causing the car to bog after so many seconds at wide open throttle

when a tranny slips rpm go up and you don't go any faster

if your rear end was slipping it would have to be skipping teeth, which would make a hellish noise, or grinding and clunking, and unless you are breaking teeth, or have some extremely worn out parts it ain't gonna happen


by just saying you put springs and bushings in the distributor means nothing to me, or prolly anyone else, unless you tell us what they were supposed to do

also i'm gonna guess with that cam it probly wants considerably more advance than just 10 degrees

 

The springs and bushings are supposed to increase the timing so that at 2500RPM the total advance is 36Deg.
