I do have a 4 sp t 10 trans but it came with the 283. Not sure if I can switch it over to fit the 300 or not. Never messed with Chevy stuff before. All seems backwards to me The c-4 I have was built up for street and strip, has reverse manual valve body and a 3500 stall speed converter. The plan was to use the 347 stroker, the c4, ,the aluminum radiator , oil cooler and the 3:70 with Detroit softlock center section from the mustang. Then put the old motor back in that and set it up so it’s a nice driver for wife. I know I can use most of those parts with the 300, and as much fun as the 347 would be I need to find out if it has a broken ring or it’s something worst from the guys that built it. My dad raced the 300 in his falcon in B modified back in the early 70s until he was up at pleasantville ,I think he said it was. That was a round track and they used to drag race on the straightaway. Unfortunately with the angle of the track and some oil that they missed from a previous car the car hit the patch of oil and spun out and smashed into the wall totaling his falcon sedan delivery. He had the motor rebuilt again, then bought a 70 maverick and had Carol bar and custom paint on it and planned to get really serious, but his dad convinced him to give it up. He sold the car but kept the motors and they been sitting in a garage ever since. I always wanted to get another falcon just to put his motor in it and give it to him. The man is 67 years old and still loves drag racing , nascar and anything to do with speed. He is an over the road truck driver and I barely see him except maybe once or twice a week between loads. This is kinda why I’m leaning towards putting the 6 in my car. It would give him something to help me with that was part his. At least until I find that falcon or maverick to swap his motor in and give it to him..
