ford used the 4 bolt main blocks on 300 hp engines for a reason.
My sentiments exactly . no disrespect to Barnett or whatever his name is heAnd OP if you set your car up properly ie proper suspension,trans,wheels & tires there is no reason a 408 shouldn't be a 10 sec ride. Plenty mid 10 sec mustangs with them(I know of one that is running 10.20's locally)
.Since we are talking specifically about 351windsor based engines in this thread, are you asserting that the OP should use a stock block 4 bolt main 351w?
If that is the case, I am not aware of any production stock 351w block that ever came in a ford vehicle. If that is not what you are getting at, then can you clarify where you are going with that statement?
.I think @84Ttop was asking what production 351w has 4 bolt mains from Ford. We all know 4 bolt mains are better for high HP apps.
Ditto . I am getting the feeling that Barnett is getting the way wrong idea of Nick here . just because nick is making 4digit numbers doesn't mean he doesn't no what it's like to still be the little guy playing or dis credits any lower hp buildsWaiting on a moment of clarity.
Exactly!!! I'm pretty sure Nick didn't start out with 1400+HP and 1.3 60' times. FOH!Ditto .

.It's more like he doesn't want people to be mis-informed.
.What ford casting #'s? The OP was talking about a roller. So why would he want a non-roller. Ah, maybe that's because its a boss block?

.If you are sticking with a stock 351 block type build, look for one from the late 60's early 70's (68-73) as these have historically held up better in my experience. As far as the lifters are concerned you can use retrofit roller lifters.
Don't retro fit designs cost a good bit more and still don't have the variety a true roller has. Just sounds like something you could do > something you should do. I just wouldn't suggest someone do something that fits their budget compared to something they should do, long term..
Maybe you should ask your friend.

Maybe its because the "old" 351's had a higher nickel content and/or were a stronger design.
Besides, as your friend mentioned, they actually have cams called "retro fit roller" that one can put in all kinds of non roller blocks.

A 302 is a 302? No! A dart/boss 302 is not a factory 302. You suggested the 69/70 was a 4 bolt main. Yes, but only in boss form..
Maybe...but a 302 ci, is 302 ci and 290 hp is 290 hp and 6800 rpm is 6800 rpm and a "windsor" based block is a windsor based block.
Below is a lowly 1990’s 4.6 with only around 215 hp yet even it has 4 bolt mains.

they have a big variety and probably a bigger variety for non computer, non efi, non smog engines for high perf builds than oem rollers.and still don't have the variety a true roller has.
if people do not know their options they cannot make well informed choices. once they know their options, they can make their own choice.Just sounds like something you could do > something you should do. I just wouldn't suggest someone do something that fits their budget compared to something they should do, long term.
