For a light race car you can get use of the HT1e because compared to the RL31, BP300 you will be able to run higher in RPM (not making more power) but the engine will not stop willing to make more revs. That's what we found when I changed the HT1e back for an RL31. I'm talking in combination with a GOOD head. Torque was better, smoother in low RPM but occasions where you wanted to stay in 3th gear until you make it to the next corner (no time to change gear), the engine came to a limit of his RPM and dropped down where the HT1e was able to keep going for an other 500 RPM. In a light car it will not matter much the lower RPM is weaker. It's not an 850 Kg Escort, more like 450 Kg space frame with nice gears
Getting past in the straight line by the same engine is usual you don't have the same power. Again, this is headwork, only minor cam selection.
BTW, very nice car, I wish a had a car like this
