Guys ive been doing some research trying to get my set up all figured out for my next truck.. and ive been doing some research and just wondering if there is a significant difference between the Texas Speed & Perf. cam lobes compared to the Thunder Racing lobes? looks like from the info i have gotten the TSP lobes are better? any info or insight is appreciated.

Thanks,
Chase

I believe Texas speed has slightly more aggressive lobe profiles over thunder racing. Also when comparing the 2 companies same cam like the TR 220 vs TSP 220 Texas speed has more lift than the Thunder racing does.

Thunder Racing 220 cam has .551 lift and the TSP 220 has .581 also the TSP 224r has .581 too.
You could always get a custom ground cam though.

EPS cams are designed by the same guy as the TR cams, but use newer lobe tech, supposedly are easier on the valvesprings. They do that while managing higher lift as well.

TSP uses Comp XER lobes while TR uses their own proprietary lobes, which are ground by Comp. Both are proven, but I'm not sure which one is "better"...
