What budget torque converter?
I could give you a few first hand experiences, with all the info you ask for (except a part #) but I wouldn't do you ANY good, because your car is different from mine....., but here goes....
My big block sixpack car has a stock 73 340 converter, that I took out of a friend's running, driving car, so I KNEW exactly what I was getting. Stock A12, 3700 lbs, 4.10 gear.
My 62 has some unknown 9", stalls 5000 behind 500 fwhp, 3300lbs, 3.91 gear.
My Tina had the unknown converter that blew up, pictured in an above post. It was replaced by a 8" munsinger, custom built for me,(now retired) stalling 5200 behind 500 fwhp, against a brake. The car picked up .2/3mph in the eighth. Weighs 2450 with me in it, 9 second street driven car, n/a small block, 4.57 gear, glide with a brake.
I have budgeted $3000 for the trans and converter I want for my Opel.
Now, does any of that info help you find a cheap converter for your car?
