I currently have the rev limit at 9k. as silly as it may sound, i need the extra 500 rpms, but can he bottom end hold it? ---

redline should be 8200 i think. buy a good valve train and give it a shot, just curious what type of racing do you do? ---

is that extra 500rpm worth destroying your motor? why do you need 500 more rpm? are you at 13.0/1 c.r, with big cams, victor x or itbs, $1100 header, headwork and 4.785 or better f.d? this is a stupid question, but i’ll help you… the weak point in the block are the rods and rod blots (which stretch at high rpm) and for the head its the valvetrain. ---

^^ what he said. unless you have internal work done, revving past stock redline you’re losing power. ---

ITS A STOCK BLOCK and its obvious that i do have cams/ springs and retainers… suprise! heres my setup with my dyno sheet. You dont need krazy compression and wild cams if you combine the right parts… sheesh… [http://www.g2ic.com/forums/showthread.php?t=149108](http://www.g2ic.com/forums/showthread.php?t=149108) ---

how is it obvious you have cams/springs/retainers?? we dont know you or your car and you didn’t state that anywhere in the thread so there’s no need to get grumpy, big guy 😃 i personally wouldnt do it, but i’m sure that block can handle it. do you plan on revving that high all the time or just for a race or something? if its going to be a daily thing, i would get it built(well rods/bolts at least). i say that because i’ve accidentally taken my b16 to 9200-9500 a few times and it runs fine. but i wouldn’t do that on purpose. i actually never take mine to redline, even racing i shift like 100-200 before its in the red 'cause i’m paranoid.:excite: ---
