i was just wondering what the stock specs are for the intake and exhaust ports...maybe like 170ish intake and 60ish exhaust?

 

I'm not sure about exhaust nor do I think that really matters, but the intake is 170cc.

 

thanks...i was just curious how much material i took out of them when i ported them.

 

I believe I saw the stock head flow numbers on Skaradoms website http://www.advancedinduction.com/AiProductsLT1.html

 

The LT1 ports I've CC'd ran from about 170 1/2 to 172. On the exhaust, under 63 to a full 65. Even on the same head, they obviously can vary. This is checking with the oem valves, btw.

 

thanks for the info man...

 

FWIW, port volume isn't really a good indicator for anything but... port volume . Don't make the mistake most do of placing lots of emphasis on it when it's nearly inconsequential, as trying to correlate port volume w/ whats important, crossectional area, doesn't work

Good luck

i was just trying to get an idea of how much material i had removed...
