Well guys I had the car at the track first time ton.... Had an issue, long storey short it's a built 383 etc... Starting out spraying 150, car has been tuned etc... I had to upgrade injectors but still havnt had the chance to swap pumps but here is what happened, car was missing on the kit pretty gd and at the top of 2nd it popped pretty good, so after that the car has a pretty good miss when u drive it but if it's idling it seems ok and revs ok only misses pretty bad while driving.... I pulled plugs and they were super lean (hazed in a green tint).... What would u guys think the problem is.... Btw oil psi and temp still stays great!!!! Any helpful info would be great....

 

Sounds like you either burned a valve or piston on that one. Ive been there a time or two....

 

well i went ahead and tore the heads off today, all looks good.... hmmm any other suggestions?
