Performing a mechanical restoration on an 81 Spider Turbo (Turbo delete). Was in storage for 15 years. Did the basic replacements , brake system, plugs , wires , exhaust with straight pipe (removed cat converter)with resonator and baffled muffler , new fuel and air filter, new radiator and hoses etc. Got it on the road and it drove but ran rough. Changed out fuel pressure regulator , cold start valve, new idle screw and o ring. Ran better but weak at low speeds (starting out in each gear) and then smoothed out as the revs increased. Was thinking of changing out the thermo switch sensor , fuel injectors and vacuum advance next. Took it for a drive and it ran as it had been. I accelerated in second gear stronger than usual and had a sudden huge plume of white smoke exit the exhaust and the engine cut out. No overheating, no oil or coolant leaks and both motor oil and coolant look normal. Towed it home and started right up this morning but it is running very rough with an exhaust pop when revving. Didn't attempt to drive. No knocks or smoke . The car did have a small exhaust leak from the exhaust manifold and always seemed to have gas fumes from the exhaust.
Looking for any thoughts as to what happened and what steps I should take next. Appreciate any help
