Hi ive recently put in a 5000 stall converter in my 98 cobra. its has a new 347 stroker. around 450hp an 430tq i think. anyway the 60ft is great. i managed a 1.57. but at the top end in 2nd and 3rd gear it seems like the car doesnt pull anymore. i cant hardly get the rpms to get to 6 grand. yet in the burnout and through 1st it shoots right up there. please post if you have ideas. guys at the track have told me the converter is to much for the car. i have a 3500 i saved so im thinking about putting that back in it to see if it improves.
