the motor for my El Camino is a 400 cid block standard crank and .030 over pistons. RV towing camshaft. 350 Vortec heads with Vortec manifold and 650 carb.. as built producing almost 400 ft/pound torque but will not run higher than 5000 rpm due to carburettor. Right now i have a TH200R4 trans with 2.72 rear. TH200R4 have low enough first gear so you will not be hampered by slow acceleration when needed. overdrive kicks in at 45 mph and get rpm to 1350 at 55mph and around 1550 at 65 mph. Will be converted to TPI system later on and 5speed manual T5 since i am not punishing engine.
Getting around 24-26 mpg and i tell you it is not slow or underpowered.

sorry forgot to tell you it is a 1986 model
