    hi guys, Im getting a XP hot cam installed soon with all the goodies....pretty sure that cam makes power up to 6500rpm. Is it safe to spin a stock bottom end that high? Otherwise could just tell my tuner to back down to 6200 rpm or so... Whats your experiences? cheers

    Talk with me about L76 springs please :-)

    hey people, Can I get away with a single row timing chain and tensioner when running L76 springs? Over here in Australia almost every performance shop recommends running Double row chain with anything higher than stock springs. The reason given is that when running stiffer springs there is...
