where to start

building a boost motor and im not sure exactly to start. its going to go in a street rod so im currently looking for a totaled lsi camaro or firebird 99+. i was hoping for about 800 whp with a tc76 or 78 at largest not looking for too much lag. im planing on building the bottom end adding some ls6 heads and a decent boost cam (high lsa). i was wondering if i was on the right track first of all and also if you would have any siggestions. another question i have is what do you guys do about high hp/tq tranies and rear ends. im assuming the stock rear end goes pretty fast and so does the trany. will the stock 10 bolt hold up after a build or is it the best idea to go with a ford 9 inch and a built powerglide or muncie. i know this isnt the best place to ask about that but i figure while im at it i might as well ask cuz u guys got the highest #s

thanks in advance for the input

i wouldnt want to drive something with those power numbers on a stock trans and rear. get forged bottom end and i agree that you dont want to be maxing out your turbo to get to your goal.

Look at the build on this V that we did this year using an LS2 block.

i use a 4l80e tranny and a 9 inch for my power levels 800+rwhp on high boost.I didnt want to lose my overdrive so hence the more expensive built 4l80 over a built th400
