[QUOTE="nightstalker865, post: 1724715, member: 131017"] before everyone jumps down your neck. I will go ahead and tell you my thoughts on it. The stock pulley is a 3.65 the most popular upgrades would be 2.93 or a 2.80. these depending on other mods will put you in the 450-480rwhp range. boost is not what kills these engines they are iron blocks with forged internals they will hold what ever you throw at them. I think I have seen stock bottom ends hold up to 1000rwhp with the right tuning of course. getting a custom tune done for your mods is a must. there are several companys that can build you a custom tune and mail it to you. RTWD and Amazon seem to be the most popular. Making sure your timming and A/F ratio is right will help you make the most out of your mods and ensure a safe running motor. but i will warn you once you start modding you will no stop it's a bug and is very contagious Eric [/QUOTE]
