not to bring this thread back alive, but im running a Tousley Reman engine with a single precision 7675 and my prior setup was 2.9 whipple. This engine is stout as hell. was making 800+ with the whippel for a year, and have ben at 900-1000 for another 7-8 months. E85 and it gets mainly track use. Auto/SRA car. Reman engine is great and i would strongly thinka bout getting another if this one lets go.
