[QUOTE="Quick Strike, post: 16611930, member: 11920"] Your intake valve is going to close further up the cylinder during the intake stroke because of the increased duration. This will lower the cranking compression a little because the valve has to be closed to begin compression. That is why I suggested another point of swept volume (or mechanical) compression compression to regain what is lost in cranking (or dynamic) compression due to the valve closing later. These cams should not lower the cranking compression in a stock engine more then 0.75:1 or drop the dynamic compression below 7.0:1. So, you will have a significantly increased charge volume at an appropriate compression - just not the ultimate compression for a 93 octane charge. Was the seller going to rebuild his engine or just add the cams? My car performs like stock at lower RPMs and putting around. Herman tunes them that way because he says you do not spend most of your time in boost. It pulls hard up to 4000 rpm and from there it hits like a 2 cycle bike in the power band until redline. Yours are similar enough to mine to be sure you will like them. [/QUOTE]
