The special 305HO th2004r converter bolts right in a th700r4 (late 30spline)
Its a bolt in. If you can find it.
None of these cams work with a low stall and no gears on a 305.
The Lt1 and Lt4 had 10:1 and 10.4:1 compression

Find the cam from a 96 -2000 L31 5-7l vortec motor
96 to 2000 5.7liter truck motor and bolt it in.
Also used in the 383HT and 350 Ramjet crate motors.
High lift fast rate of lift short duration a improvement on the cam you got.
good torque in a 305.
