Ok so im going to be putting a turbo on my 93 notch in the very near future so im trying to get my engine worked out first (I want something thats gonna live for a while) I was looking into a single turbo 331 lookin to put down around 500 to 550 to the wheels. While I was looking at 302 blocks it hit me use a 351 instead!! But how much power can the stock 351w handle and would the stock rotateing assbly be able to hang or would I need to go forged? If it needs to be forged does anyone have any recommendations where to get it I would like to keep it a 351 for strength. Thanks guys.

*Edit*
Also we have a 79 F-150 sittin in the driveway that has a 400ci in it is that a totally different engine or is it a 351w based with some kind of stroke??

ok first forget the 400 its completely different in every way, youd have to run a c-6 just to use it because of the large bell bolt pattern. a 302 can handle 450 hp if carefully prepped, turbos can be rough on bottom ends so i would say forged internals all the way like crank, rods and pistons, youll need custom pistons anyway for the turbo, plus with the 302 you can use all of the bracketry and accessories you have now with out having to modify anything, with a forged bottom end, good hardware and a main girdle the 331 will work very well, hell if your gonna put the cash down for the 331 (which is a great kit dont get me wrong) why not get the 347 kit, the little bit of cylinder bore clearancing needed wont hurt anything. and youll gain a little more power for probably the same cost. yes the 351w will work also but at 450-500 hp your at the limit for the cast crank and rods, again custom pistons will be needed. the thing is with the 347 thats it for displacement! if you go the 351w you could in the future get 427 ci out of it. 427ci with a turbo setup!! hang the hell on son! it doesent hurt to overbuild a motor for strength, if you dont build it strong enough youll spend double than if you did it right the first time. good luck sounds like a fun build.

my 302 is holding strong at 582 rwhp but then again i dont run it hard very often, but most 302's are rated around 450-500 for the stock block, as it cracks down the main webs, now a 351 w is a much stronger block but as said the safest bet would be to build the rotating assembly either way. forged all the way

most 351s are limited to 600-650hp

maybe stock...have several 351w cars at 800-1000 rwhp range, aslong as you dont hit the limiters get spark ping or knocking its safe
