Big Power!!!! Help

[Travis B]

Building the ultimate 350.. 450-550 horsepower plus and 575 torque plus.. I have a 350 4 bolt main 2 piece rear seal.. Just had it bored .060 over. I believe this makes it 388 cu. with 4.060 bore. Correct? First off was wanting opinions on whether to stroke it or not? Should I stick with a 3.48 stroke which is stock or jump to what I believe would be a 3.875 stroke because of the bore size, since it can't be a 383. I was planning on using SCAT 4340 forged crank and Forged H beam rods. With choosing the crank arisies the question of rod length. Stay with 5.7 rods for durablity or go with 6.0 rods. I don't know alot about this area so all comments are appreciated. Next was going to use forged pistons because of the horsepower and torque I was looking for.. Should I go with SRP, JE, or Keith Black, but unsure if the KB pistons come forged or with a teflon coating? Have yet to call them. Which brings up another question on whether to use teflon coated pistons or not. Have heard several opinions but would really appreciate it from true gear heads with big muscle investments. Some say don't worry about the coating because it will burn off anyway, but then why would OEM replacements come coated now. Also I am going to use flat top so I can later install an ATI procharger D-1SC. I am also going to use moly rings. Again I am also looking for the proper quench rate... Again have done my math for clearance issues and think these combos are okay, but maybe someone with more know how can double check me and let me know.. My goal is to build a rock solid bottom end, ie bulletproof ha ha. And then build a solid top to match. I was going to use comp cams.. something with around 540 lift due to clearance with a spring rate of 117 closed valve to 280 open valve. I was going to use roller rockers and lifters. I was wanting to have great mid range power all the way through the power band from 1900-6500.. Any cam thoughts are appreciated. Also I don't really want to have to tear down and rebuild every couple thousand miles, would like all this meet my hp and torque goals and still be durable and have good engine life. So please if I have missed something correct me and let me know which way I should go. The obvious choice for heads was AFR aluminum 195cc 68 ci. I have a Edelbrock performer intake and was giong to use it unless you guys think the air gap would be better. Also have a Holley 750. It has a M-21 close ratio tranny but know how long this will last due to the power. Any tranny suggestions? Was thinking TKO 500-600 or maybe a Richmond if you think it can handle the power. I have put alot of time in this so far and will continue to due so over the next month for mock up, blue printing, and final assembly. Not to mention the $4000.00 dollars it will probably cost to complete this build. So all gear heads please help with suggestions and opinions on what I am thinking about building. Do you think these combos are good or not.. I plan on having a 10:1 compression. Also if anyone knows anyone to get great deals on parts let me know.. A dollar saved is a new dollar towards horsepower increase. Thanks

First of all if you haven't built the bottom end yet I would stroke it, that will get you a lot closer to your torque goal! However with some of the parts you have listed I don't think you will reach 500hp! The first problem I see is the intake, that performer wont allow the rpm you are going to have to turn to reach your goal! And I could be wrong but I don't think your cam is big enough to reach 500hp-550hp! I would go with JE or SRP pistons for sure! 10:1 compression won't be optimal for the procharger it will detonate like crazy with very much boost! Maybe WELTERRACER will chime in here he has had a couple of bada** sbc!
