How to calculate the cylinder volume for the speed density systems?? - Third Generation F-Body Message Boards

Ok, planning a little 383. The 350 has 713cc/cyl and the 305 has 623cc/cyl. I divided the 713/350 and got 2.xxx, then I took the 2.xxx and multiplied it by 383. Would that give me the correct value?

Just doing some homework before its time to tune the thing, it stinks having to look at the shiny new parts sitting next to the computer..

A 383 = 6.271 Liters or 784cc per cylinder. Due to "rounding" from storing in hex, the value may differ by +/-4 when you re-read it.

I did the math correctly then.

Thanks Glenn
