From what i here comp cams makes good blower cams for the 4v, and while you are that far i would have the heads ported and new valves ect.. at least thats what im planning on doing to mine. im running a procharger p1sc with a 12lb pulley and a safe tune with an SCT scanner. Guy i bought the car off said dyno'd at 502rwhp. As for the internals, mine are still together and im running a stock bottom end (knock on wood) but fr when the day comes that i fear somthing will happen i have a 03 cobra short block ready to go in, havent decided if i want to stay with the 01 alluminum block or the 03 cast block..... anyone have any suggestions for me?
