No. But yes. But no.

I think the older version he has was called the iron eagle and now they are shp

Not sure what the differences are, but the dart blocks have a thicker bulkhead than oem causing the chain issue

Negative.

I have a Dart Sportsman block. They are stronger than an SHP, but not as strong as an Iron Eagle.

They stopped making them quite some time ago. Reason being is that the SHP blocks were known to be an anomaly. Dart blocks had a higher nickel content back then. The SHP blocks were so strong there was no reason for people to buy the Sportsman blocks, so they discontinued them. At least that is what Dart told me and it makes sense.

These days the SHP’s are not the same as they once were. I want to say Dart told me they are good for 700HP (advertised). They told me mine would handle 1300.

I'll stab someone if these have a 700hp limit

I know my limitations and can do lots of things building our cars but I pay for my engines and transmissions.it is money well spent. But I admire his willingness to learn , that’s why I hate to see him get trashed.

And you probably have someone you've known and trust 👍
I build my own but have a buddy with an engine shop that I trust to do my machining. And I have a buddy that's been involved with a nascar team and super stock etc that builds engines for a living to ask questions.My xe block needs line bored and I had to find someone else. Makes me nervous as hell. Trying not to bother him as they are crazy busy but it's been a couple months now.

I think of a limit like that as a total all out race deal, getting constantly abused.

Maybe they have to leave a safety factor when asked that question for liability. I don’t know, but I do know for a fact they are not as strong as before. They no longer have the high nickel content like they once did. Remember they changed foundries and all that around Covid and a lot of shit changed.

I’m sure one of these guys that are still tied to the industry could tell us more.

Edit: I think that is also why 69 Windsor blocks were sought after. High nickel content.

Known my engine guy for 30 years since he was wheeling a Jr dragster at 14. Trust him fully.

69/70 was good for the windsor. Only decent oem heads they had. Can't remember if the block had thicker cylinder walls also.
Brother had his 306 running 12.8 with those heads, went to afr 185's and got a 12.1 but ported the intake and worked on the exhaust etc. Those 351w heads are pretty good

69/70 blocks were better and had shorter deck height.

That's why my first engine builder is a cock sucker and all of the reason this thread exists 17 years later

That block is in a garage somewhere.

The 84 block is in a garage somewhere else.

This dart block is in this garage here..

This game sucks
 
You ain't gonna be making enough steam to split it in half so don't worry about it. You could just be slapping this together like the previous so called engine builders you had.

Yep, just can't remember if they had thicker walls.
Yes, probably why you're building it yourself this time. It can be frustrating at times, and rewarding at others.
 
Don’t take this as a dig, but you are talking to too many people. Pick someone you trust and listen to them and only them. You are hearing different opinions on every aspect and then you start 2nd and 3rd guessing everything.

You are going to have to massage things to get them to fit/work. That’s part of this game. Be decisive, make a decision and run with it.

The car is going to be what you want it to be, but you just have to fucking DO IT!!!

My xe block is high nodular but also solid oil pan rails, main webs and thicker walls. It seemed malleable while deburring.

So far I trust none of them.

Finding a reputable Ford guy is like finding a red headed girl with brown eyes.

I walked into the local machine shop a few different times this week and you quite literally can't have a conversation with them because they know nothing about ford. I didn't realize how many differences there are between the two manufacturers.
 
I told you quite some time ago, I have a local guy that is a true blue Ford guy, he would have had this thing done a long time ago for you.

Right now he is slumming it and helping me with my wives SBC. Probably has to take a shower after working on the Chebby stuff! :)
