Feedback on first few days

Being a auto enthusiast I find this game very addicting lol. The engine builder is very user friendly and offers alot of choice. I know the flat head engines, V6, inline 8, v10, v12, and v16 will come eventually. I do see a few things missing that would help offer more choice in the engine designer.
1. valve location. Buick used a vertical valve OHV design in the 50s and 60s with great success. Having a option for changing valve angle would influence the power and torque curve
2. I know people have complained about pushrod engine design being weak in the game. There should be a option for shaft supported rockers or pin supported. Most US v8s in the 50s and 60s used rocker shafts which allowed for very high revving but lowered breathing ability. Then the option for roller rockers vs flat tappet which decreases friction in push rod motors.
3. Valve diameter adjustment (intake VS exhaust)
Aside from those 3 things I can build just about any motor to fit my gas guzzling, affordable, monstrous, V8 fancy! Im addicted to the game already!
Cheers!
