[QUOTE="na svt, post: 15228755, member: 35346"] I said advance the cams and the reason for that was shape of the powercurve, nothing more. The ability to do so would increase avg power over the upper 3000RPMs of the powerband while reducing peak and power after peak very little. If proper consideration was given the to lack of PTV clearance the cams could be advanced. However, the pistons should have had reliefs in the first place. I can show you a pump gas engine that makes 390+rwhp. Many engines have made similar or more power but not everyone posts on SVTP or the other forums for that matter. Making big, n/a peak power is not hard with 4Vs as their heads even in stock form flow great. A friend recently, after a cam timing change I suggested made 480rwhp @7800 with totally stock 03/04 heads. Hell, the heads still have the factory valve job. A simple opening of the valve seats would put this car over 500rw. I only pass on information gathered from first hand experience over the last 15 years with mod motors. If something worked, or didn't work for me I let people know. They can use this information as they please, but don't tell me something won't work when it did. Brandon's engine had ported 03/04 heads, an FR500 intake and cams with .480 lift. How does this differ greatly from the OPs setup? [/QUOTE]
