I have a 65' Tempest with a 67' YT 400 with 670 heads and TH400. I purchased the car a year ago and have been driving it every day since. As far as i know it is stock and now i am having valve train issues so i feel like it is time to rebuild the top end of the motor. So i will be replacing cam, timing gear, lifters,springs, rockers and push rods. I want to drive it on the street 75% of the time and take it to the strip the other 25%. So I am looking for suggestions on cam kits. I was thinking this one https://www.summitracing.com/parts/cca-k51-240-4. Please let me know if this one would be good or should i go smaller on the cam.
