These TCI StreetFighter converters are completely remanufactured with furnace-brazed fins, needle bearings, and a flame-hardened hub. StreetFighter converters will give you about a 3,000 to 3,500 rpm stall speed. They're recommended for use on high-compression street/strip engines and higher performance cars and are used on some of the fastest street machines the world over. Plus, some applications are available with an anti-ballooning plate for use on vehicles equipped with nitrous oxide...convertor is a year old..has 200 street miles and 10-15 1/8th mile passes on it....not big enough for my motor so i had one build for it..paid over 450 for it will take 350 obo or might trade on lsx parts,slicks,drag radials,nitrous stuff,powerglide or drag racing parts...partTCI-241001...call text or email...423-637-7188
