Anyone use this box on any big block engine? Ive just sold my F20 after somehow blowing 5th gear last year. Iv had a spare F18 for a while that i took off a J plate 2.0 8v Cally and ive just checked the part number and realised its a C357, which according to a table ive found is the CR box and is 0.3 quicker on 1st gear and 0.2 slower on 2nd gear (thats if what understanding of ratios i have is correct lol) difference from an F20?, People say that the F18s are no good etc etc but im gona give this one a whirl i think, whats peoples experiences opinions?? Heres said table -
F18c (3.57) 3.58 2.14 1.48 1.12 0.89 3.33 3.57
F20 (3.55) 3.55 2.16 1.48 1.13 0.89 3.33 3.55
