360 to a 408 how much quicker

* 750 Holley or Quick Fuel - with choke tower and flap.
* 904 w/2.71 low gear
* 4.86 rear
* Sunoco Purple
* Cam has 270*+ duration @ .050"
* Low tension oil rings
* Everything blueprinted by an engine builder who knows what works best under the rules - valve job, honing stones, ring gaps, etc.
* Honed with torque/deck plate.
* Lightweight oil and rear end fluids.
* Converter that flashes to 5,000+, but I shift around 66-6700.
* Light wheels and tires.

I picked up with a TTI X-pipe and Dynomax Ultraflos after some jet changes, found that a dual plane intake had more torque and actually flashed the converter higher by a bit, but a single plane was faster and run Hoosier 9" lightweight radials. Despite being "touchy" on marginal tracks, they are faster than bias ply tires and I have my suspension hooking well enough at IHRA event prepped tracks to be consistent. One way to look at it is that, despite not making a "lot" of HP (running a best of 115 so far), I am using the available HP and torque "efficiently" to run a best of 11.31.

These are just a few things that help to go fast and I'm always tinkering. It's a never ending learning process. My engine builder has his way of doing valve jobs, honing, etc. It's not just "parts". It's figuring out how to tune them and pick them to work together. It's not just what you put together, it's how you put it together. But this works for "MY" combo. Plugging in some items into another combo may help, or may hurt!

But, as mentioned, there are similar cars that are even faster! They have more time, money, dynos, etc. I started out running low 12's in 1999. So it's taken me 10 years of testing, tuning & refining this combo for a gain of less than a second under the rules so far. And I still have more to learn.
