A stock RX7 will be faster than that boat anchor 267 Chevy. From a performance standpoint that is just about the worst small block you can choose. It has tiny cylinder bores that will not tolerate much cam lift, 1.94 intake valves will not clear the bores either. The small cubic inch displacement won't like much cam duration either.
I had one in a 79 Malibu Wagon and it had over 230,000 miles logged on it before parting with it while still running great. A very weak but long lived small block. The little mouse even towed a 23 foot boat but sometimes depending on how low the tide was we needed to run the boat's motor to help pull the boat and trailer out of the water! This engine got beat on allot but like a volkswagen beetle(the early ones) didn't have enough horsepower to hurt itself.
It got pretty decent mileage too but was definitely a product of emissions/fuel economy thinking back in the dark ages. This combo was not designed to make allot of power.
The 267 has little performance potential but would make a great pump house motor! LOL
