TQ Advice

Many factors play a part in choosing the right convertor. Best bet is to call a reputable convertor manufacturer and provide details of car like cam, weight gears etc and they can steer you to a convertor you will be happy with. My recomendation is to buy the right convertor the first time because even if it costs a little more it's cheaper and easier than buying multiple convertors and replacing them because you are unhappy.
Can't agree more with this statement. You must be honest with the information you give the convertor manufacturer or you'll get the wrong one for "YOUR APPLICATION".
Too many times over the years, I saw good money spent after bad, as the wrong information was given at the time of the original purchase. Buy from one of the builders that have been mentioned on this board. Don't let price be your only guide, and avoid used converters as you don't know what the original application was or what the condition of it's like inside.
I understand the budget thing, as I'm sure we've all gone through it at one time or another. Before you decide on a stock or modified converter, find out what your combination will need and go from there.
