That explains it. Honestly, my 2001 Cobra I sold not too long ago was a bit of a disappointment in the engine department. The stock setup seemed to get the engine confused. The long intake runners are a setup for the low end torque but the engine architecture, 4 cams, short stroke, 4 valves per cylinder are a rev happy bunch. So the result, predictably, was not much low end torque and nothing above 5000rpm. After a while it didn't even want to go there. For comparison I have a Maserati 4200 with a similar, on paper, 4.2l 4 cam motor and it revs happily to no end. Both cross plane crank design except the Maserati has variable valve timing. I was thinking of swapping in the Boss 302 intake into the cobra as those runners are short and big for high RPM power.
When I called modular motorsports, my local modular engine builder they quoted me $8k to rebuild the motor properly. 8K! I could sell my cobra, buy a coyote powered car and would still be ahead money wise haha..
