kubus Posted June 4, 2018 Share Posted June 4, 2018 Hi there Guys... I've tried to search here - and everywhere else - but all is mixed up. How does the stock Cam - P90 - gonna work in a ported head ?? all reworked intake / exhaust on Garrett GT3071 etc. etc. I'm more looking into low to mid end torque for street Use - not a drag queen... any suggestions ?? stock is good ? NA Camshaft ? uprated ?? thanks. Quote Link to comment Share on other sites More sharing options...
