Not sure If Ive put this in the right place, but I'm sure I will find out...
I'm building a 408 Clevo stroker to go into an XE ute, but going to run straight gas (Gas Research) as I plan for it to be a daily driver and dont want emission problems from the EPA again.The bottom end is almost complete and the next step is the heads. Does anyone know of the ideal head for Gas and this cube combo,AFD, CHI, Kostecki??? 2v, 3v, 4v...even factory cast...., or do you know of where I could get a comparison of head performance....Thanx |

Send me a message when you have bought your GRA throttle bodies as I have made some annular discharge venturis which will increase your CFM flow as the GRA flow figures are a long way below what they are quoting.

What models have you bought S400 / S440? Those are the quoted flow figures but the 440 will only flow around around 298 to 308cfm at 1.5'. I have made up various different venturis that will lift the flow between 385 and 422 if your feeding a stroker.
