Need new torque converter but what size...???
I'm working on a 73 olds omega with a stock th350 transmission and 350 rocket. I do have an after marker RPM performance intake and cam with a holly carb. My problem is when slipping out of park to 1st I get this huge jolt and will usally stall unless I feed some gas just before the gear change. I'm almost possitive it's because the stock converter can't compinsate for the power. My father is saying I need a converter in the 2800-2900 range but multiple auto stores are saying a 2400-2600 will suffice. If I do get the higher range one will that be michanicaly okay for my car or should I stick with the 2400-2600. Please let me know what you think
Ps. If you know what range the stock converter is that'd be great to know too.

Most stock converters are around 1800 rpm.
If you get a GOOD quality converter it wont feel mushy at part throttle. I would go 2600-2800. Im pretty sure Coan doesnt charge extra for a custom converter.

What rpm is it turning when you put it in gear?
I wouldn't think about changing a torque convertor until and unless you are sure that is the problem. Reminds me of when my 69 GTO back in 1972 was having a hard time going more than 45 or 50 up hills on the PA Turnpike. I was "sure" it was a fuel pump, so I pulled into a service station and told the mechanic I needed a fuel pump. He installed one and I paid him, but it had no effect. I paid for an unneeded repair, and he was correct when he said I didn't ask for his diagnosis, I asked him to put on a fuel pump, which he did.
