540 bbc upgrade ideas
I was wondering what I could do over the winter to get more hp for the money. I have a 540 bbc with dart 355 cnc heads. It has 13.5 wiseco pistons, 6.535 rods, 4.5 bore. The cam is a ultradyne .765 int and .714 lift exh, duration is 276 int and 284 @ .050 with a 110+4 centerline. Eldelbrock tunnel ram( port matched to heads), bird catcher injection with high speed lean out. PG and 5500 stall. 4.29 rear gear and 33 tire. In a 1900 lb altered. My best time was a 1.1375 sixty foot and 5.16@131mph. I average 5.2's all the time and a 1.1430's sixty foot .
Is it possible to get in the 4.9's with some head work or flycut the pistons to get a larger cam. any ideas
