I think they are around 190 on the exhaust duration and 130 on the transfer

timing but I am not sure...it's a reliable drag port...not too radical. Call or

email Rick at RitterRacing (see link above) if you would like more technical

details. He likes relatively high transfer timing to allow more time to draw in

the fuel charge because he does not like to hog out the intakes too much because

it reduces intake velocity. He also does not like excessive exhaust port timing

which will reduce your cranking pressure, but as you can see, the exh. ports

have been widened conciderably to help with expelling the spent charge.
