1970 w-34 questions

hello everyone,
I have just purchased a 1970 455 out of a Toro. The gentlemen that i purchased it from stated it was pull from his uncles 70 GT and was a running motor. The vehicle was in a collision and totaled the car. I recently purchased a nice 1969 #matching 442 and was wanting to keep the original 400 saved and out of the car. so thats why i picked up this motor. anyway i have checking all the casting numbers,julian date code and everything checks out. execpt the distributor. My question is related to that. the # on the Distributor is 1111048 6G25 my understanding is this is for a 1966 330 MOTOR. can anyone shed some light on why this might be installed?
thanks, Scott

I realize the only way to know for sure if its a w34 is to pull the cam and check the number without having access to the cars vin

My guess is that the "collision" pushed the engine back to a point of distributor hitting the firewall.....and damaged. My concern would be if anything else was damaged from the impact between the two cars.

Given how far forward the engine sits in an early Toro, how much of the trans sticks out between the engine and the firewall, and how much clearance there is between the distributor and anything solid, an impact that severe would have done irreparable and obvious damage to the engine. I suspect there's a different reason for the swap.

??previous owner changed the distributor??
Does Toro GT make it a W34??

Trans axle would have OM on the tag
drivers side



I would not worry about cam markings

my understanding as I read the info from this sights FAQ is the GTs are W-34s. doesn't really matter it was just a performance cam as far as the the motor is concerned. My line of thinking was more that maybe there was some oldschool trick that increased performance. Doesnt seem to be the case. as for being replaced after the accident the car was a total loss thats why they pulled the motor.
thanks guys

RPO W34 was the Toronado GT package, so yeah, all GTs are W34s and all W34s are GTs for 1970. The W34 motor was the same as the Delta 88 W33 motor and the Delta Police Interceptor motor. It was also the same as the 442 automatic motor except that the 442 was rated at 10.5:1 CR while the W33 and W34 motors were rated at 10.25:1. I caveat this statement, however, as the engine assembly manual shows that the 442 and W33 motors use the same P/N piston and rod assemblies, so they have the same pistons and thus the same CR. Don't believe the marketing documents.

All three motors used the same 285/287 cam and big valve E heads (note that the W33 was the only B/C-car motor to get big valves for 1970). The 442 and W33 used the same '251 Qjet with .070 primary jets, 52C primary rods, and AU secondary rods. The W34 used the '252 Qjet which was identical to the '251 except for the use of 49B primary rods. Of course the W34 was saddled with the depressed Toro intake and crappy exhaust manifolds. Despite these miniscule differences, the W34 was rated at 400 HP/ 500 ft-lbs, the W33 at 390 HP/500 ft-lbs, and the 442 motor at 365 HP/500 ft-lbs.

Once again, don't believe the marketing documents...

I long ago gave up trying to figure out why people do weird things to their cars.

Could be a simple as they damaged the original when pulling the engine.
Or a million other reasons...
