I could see that happening as the 318 is such small displacement it's not a torque monster to begin with. Then you add a single plane intake and a really big cam it's even worse on low end torque. Heads and compression ratio being another consideration. If you had small valve 318 heads that didn't flow good those parts wouldn't work well at all. You probably needed at least a 4000 stall to make that combo work right even with good flowing heads and decent compression.
