hat1324 Posted April 17, 2005 Share Posted April 17, 2005 Ive been looking to do a ford 351W swap into the Z. But no one in the ford community can come to a concensous(sp?) about the stock capability of the block. and Only certain years can hold more power. My ORIGINAL plan: 351W Stock crank, forged rods, forged pistons, girdle, arp mains, arp rod bolts, arp headbolts, 77 bearings, stock oversized or upgraded heads, custom manifold, single turbo(.80 or larger), 3" all the way back, the $300 intercooler(mentioned here), BOV, Holly 750 blowthrough, Walboro 555, MSD 6al, HVC coil, MSD distibutor, relocated battery, and and and..... I want a VERY reliable conservitive 500 - 650. They say that the 69 and 71 blocks for ford are rated there, but they dont know, and its a constant battle. The chevy swap stuff is allready made, and swapping is far more common. Less original but easyer.. WHAT I WANT TO KNOW: What is the stock rating on the 350 BLOCK(not hp from a stroker) whats the block hold. Whitch Junkyard cars can I steal from, and witch years have the 4bolt main? I dont want to spend all the cash, just to have it snap down the center. NOT going aftermarket block. Quote Link to comment Share on other sites More sharing options...
Guest iskone Posted April 17, 2005 Share Posted April 17, 2005 500hp is the most common upper limit on a stock 2 bolt block. But most will say 450 You can make it stronger with splayed 4 bolt mains and block filler up to the bottom of the freeze plugs max. You could get closer to the 600ish but I'd be weary 550 is more likley Of course it all depends on how well the engine is put together and how you take car of it.

SmoknR6 Posted April 17, 2005 Share Posted April 17, 2005 APR bolts and billet caps will do the trick. Quote Link to comment Share on other sites More sharing options...
Guest bucnasty Posted April 17, 2005 Share Posted April 17, 2005 APR bolts and billet caps will do the trick. not always ive seen 351c's take plenty of abuse stock, the 351w is a great foundation, i personally always wanted to but never got to build a 427 stroker on that block. that is what saleen is using on the s7 btw. 5.8 weight 7.0 power. hes doing 450 na street version, 550 race version. dont know how many turbo motors uve built or ran, but turbo motors always break stuff. not complaining, just stating the truth as im a turbo addict. i personally like the spearco and precision core fmic's. precision and innovative turbos also. tial/hks/innovative wastegates. tial/hks bov. there is also the 351m the mexican block which had a different alloy composition i remember reading about in a mustang and fords magazine a few years back. hope any of that info or blathering was helpful. good luck on the project. Also look to see if u can stuff a ford fe serie big block in there, as they love nitro lol. chris. Quote Link to comment Share on other sites More sharing options...

jt1 Posted April 17, 2005 Share Posted April 17, 2005 I want a VERY reliable conservitive 500 - 650. If you mean 500 - 650 horsepower, you're dreaming. Very reliable, conservative engines of this horsepower range, suitable for swapping into a Z car, do not exist. Engines making this amount of power are highly stressed, high maintenance items. Probably the closest thing to your requirement is a modded LS1. WHAT I WANT TO KNOW:What is the stock rating on the 350 BLOCK(not hp from a stroker) whats the block hold. Whitch Junkyard cars can I steal from, and witch years have the 4bolt main? 1st gen 350's have been produced by GM with horsepower ratings from 370 to 165. "stroker" is a term refering to the crankshaft or the entire engine, not the block. The block holds internal moving parts, such as crank, rods, pistons, etc, plus oil and coolant. I don't recommend stealing from junkyards. Typically they are inhabited by large ill tempered underfed dogs with sharp pointy teeth, and ill tempered owners who don't like thieves, or buying dog food. And, there's law enforcement to deal with if the dogs don't eat you first. What's a "witch year"? Is that a term used by ear jewelry salesmen to inquire where you want your lastest purchase installed? John Quote Link to comment Share on other sites More sharing options...

Problem is there that they make WAY more then I want. Im up with maint.. but dont want to change a piston weekly. Ive asked about stock blocks before, and people say"with a 427 you could get blah blah" instead of the block and Ill remember to bring a steak.. Now all i have to do is find a turbo rated for my power. All the ones for sale on TurboMustang are for 900HP and i dont need that much. 351W(mexican) is UBER rare, even more so then the 302(mexican). i still havent decided what turbo to go with, boost I want 12 - 14PSI Quote Link to comment Share on other sites More sharing options...
Guest bucnasty Posted April 18, 2005 Share Posted April 18, 2005 go to www.innovativeturbo.com precision turbos are nice also well good luck on the setup man but for nice built ford motors go to www.coasthigh.com great stroker kits, shorts and longblocks, or custom setups chris.
