$100 351W junkyard block. LOL. We would NEVER pull any sort of 351W or 302 engine for $100. What kind of junkyards do you guys have around you??? I'd be losing money spending the time it takes to pull a motor for $100.00
Well, I can tell you that my brother's shortblock is a $50 302W that wasn't touched.... He just bolted on his stuff tuned it himself and is currently making over 400rwhp with it. He's been driving it that way for the last 2 years.
Last time I was at the JY, there were maybe 20 complete 351s, and out of them maybe only 2 or 3 were actually roller cam (which, personally I would only consider roller for a performance application).
The 69-72 blocks have thicker main webbing - I've seen this in a side by side comparison with my own eyes. It doesn't take much to convert them, but I'd stick with a roller too if I was looking for a complete shortblock.
From what little I know of you, I'll have to admit I am humbled to be in the presence of a true know it all. You're the second one I've encountered on this board. So, God,
Alright, first cut the personal attacks out. I wasn't personally attacking you with anything that I said, and I certainly didn't call you any names. I'm not sure if you're doing this to a moderator to show you're tough or what, but if you do it again to myself or anyone else in this forum you'll be on the sidelines of this discussion for, depending on the severity of your actions, for an appropriate length of time.
Now as to your particular comments, I suppose I'm a know-it-all because I disagree with your comments. That's going to happen on this board. I've been doing the 5.0/ford mustang thing since I was 15 and bought my first. That was 14 years ago, and I've owned 3 since then with no less than 5 different engine combinations. That's not much, but considering I live and breath this stuff, I think I have enough expertise in the subject to have gained the respect of a lot of people that I've helped along the way both on this board, at the track, around town, and on plenty of other mustang boards. Furthermore, I have as much right as any to voice my opinion in these forums. If you expect to post here or anywhere on the internet without disagreement, welcome to reality.
Do all of your engines just go from initial startup to "well tuned"?
Usually not far off, actually. WOT is a breeze to tune with basic distributor and fuel pressure changes. Otherwise, I do have both a Tweecer and a Big Stuff 3 and my tuning skills are constantly improving. "Well tuned" is probably the wrong choice of words. Drivability is inconsequential when it comes to preventing the motor from self-destructing. Safely tuned would be more accurate i.e. keeping the AFR at around 13:1 n/a and around 11.5:1 under boost. Timing-wise, I like to start at 16* under boost and work my way up to the best trap speed.
"Shifted at 5500-6000?" what were you doing? going shopping? Is the "rare example" that you're wrong, or the failed windsor?
All I took from the "going shopping" comment is that you shifted your motor significantly higher than 6000 RPM, which validates my speculation on how yours split. It's too bad that I come across as a know-it-all. Unfortunately, here's one more thing I know that you probably won't like: 2-bolt main 351s are going to experience crank walk no matter what you do at somewhere between 7000 and 7500 RPM, and can experience it below that without a girdle which only helps a little (a few hundred RPM). By the way, when you've got a turbo, there's nothing wrong with keeping the RPMs there; if you need more air, you can always turn up the boost
The engine had a 4340 crank, H beam rods, 13:1 Ross pistons, and a cam W/ a power band to 7k. Stupid me, I should've known better than rev it to 6800.
haha, I hadn't read this before hitting the quote button and responding to the previous comment. This confirms my suspicion. 6800 is actually pushing a 351 pretty hard, brother. Now, I guarantee you crank walk led to your split block. I can see you don't believe that so we'll agree to disagree, then. I'd love to see what the crank and mains looked like afterwards.
Strangely enough, Ford felt the need to offer a Sportsman intermediate block. I guess they did that because the stock windsor block is so durable.
Oddly enough, they offered a 302 sportsman too - it was no more durable than the stock block.
The last time I checked w/ the guy at Motorsport, (today) He wouldn't advise relying on a stock block beyond 500 FWHP, and stated that the tune was relative to the durability, but getting there was what killed it. Lastly, that they always cracked in the main saddle.
getting where? To a safe tune? Why wouldn't you start out on the safe side?
It's not sacrilege to do something different. If you don't like the car, treat it like you were in front of it at a car show, and walk on by.
I agree with you to a point. It's not sacrilege. If I saw the guy at a car show, I'd either walk on by or give him props for having a quick car. With regard to Stangnet, it's an open forum that allows any member to respond to any topic.
Coming from experience, I had my fill of " forum experts" on the Starion/Conquest Ricer board I used to frequent when I had my Ford engined Starion/Conquests. The Starion had the n2o 393w, the Conquest had an R302 block'd TT363. W/ the pictures as a testimonial to how the builds were done, all I heard was "Why didn't you use the 4 cyl?; "Why didn't you use a 340/360 in a Chrysler as opposed to a Ford motor?"(even though it was a japanese car) "Why would you get rid of the IRS and swap in a ford rear?" (Despite the fact that the half shafts were cast 3/4" junk.) "Why did you ruin a perfectly good car?" AND "Why didn't you put that in a mustang or some other Ford where it belonged?"
There was a small percentage that liked it for what it was, but for the most part, this is what I got.
Sorry you had a bad experience with the other board, and I apologize too if you're having a bad experience here. I guess I'm a forum expert. All I can say is, hey man... that's the internet... Hopefully, we can still get along.
I agree w/ you. Being polite only goes as far and as long until somebody comes along and makes a smart assed one line post about how this or that sucks. From there, it's
then
Yes, but be careful. While you're free to state your opinion about just about anything, please refrain from name-calling and personal attacks as they will not be tolerated. I'm sorry to come off like this to someone so new. I've never had to throw an iron-fist around in the fox forums, and I think the fox guys tend to be a pretty mature crowd. As far as I can tell, unlike all other moderators, I don't have a problem with any of our members, and I've been around nearly from the beginning.
Chris
with your fellow racers.
