Stock Stroke 340 Build with NC Engine Builder

We went round and round on the solid roller cam and it’s an involved story, but in the end, there were going to be delivery issues due to the availability of cores and the relatively small lift of what I needed exacerbated that because most cores available would cut through the hardened layer to get down to my lift numbers. Howard’s, Bullet, and Scheider all came in fairly close to each other and in rising order of aggressiveness. I probably would have gone with the Bullet offering. But as we talked and Shawn got to playing with the heads, he felt that the SFT that I brought would handle the job. It would also save close to $2000 in parts for the cam, good roller lifters, and melonized oil pump drive. I can spend that money elsewhere or put it away for future improvement. God knows I’m not done spending on this car! Here is a summary of the offerings and then the custom Comp grind that I picked up used. It’s about a step smaller than the smallest roller
