any 4 speed racers out there?? post them up

i run a 1970 .030 340, standard 318-3 truck crank, stock bushed 340 rods,heavy trw 13.1 pistons, ported j heads with ductile iron rockers and a solid camshaft. i can say that the 23 spline worked very good but in a 3365 lb car it was hard on third gear so i switched to a 1-1 4th doug nash and no more problems. my car is a 1970 dart and has run a best of 94.75 on a 7.13 with a 1.52 60' on super stock springs with a 9x29.5 tire and a 5.13 gear. this car has bolt in frame conectors (not recommended). motor and running gear is in stock location.
