Im DEFINITELY NOT going iron. Im just NOT. Dont care, im not doing it. I was kikn it back n forth last night with Darth+Che70velle. There are reasons, including out the door costs, to simply keep the RHS block. So I will. Thats off the table. Whether I end up doing a stroker crank or stay with 4" stroke and less cubes, I think its gunna be ok and still get me north of that 730hp, or 600 at the tire. Thats the real goal. My car is built for pro touring in its suspension/stance/wheel package/etc. It does have a very nice 4link+coil over set up w/full adjustability. Only goals I have are to drive it like I stole it. I will beat on this car! Im just not settling for "enough" or "plenty". Because reality is, its never either. Street, strip, whatever. Its just never enough. We gunna reverse engineer this next build. Work backwards from the intake mani, heads, compression, and cubes. Willing to ditch max effort for some driveability and a nice area under the curve. We ll see how this progresses. Im not ashamed im asking so many questions, and heading down different paths on the daily basis. In the past, I just went with someone elses idea of what it should be. No more. Until I at least understand what Im asking for/getting.

I would do 4.100 stroke crank and 4.125 bore if i had to do my build over from scratch. My setup makes huge power and i spray 300 shot at the track. My 4.125 x 4.125 works fine though and my crank was fine so kept i just stuck with it. There is absolutely nothing wrong with a 4.125 stroke crank. For the millionth time IF IT'S BUILT RIGHT!

The builder needs to know piston skirt design as far as the application detail stroke wise. And of course attention to detail is a must as far as piston clearance and the bottom of the bore being chamfered correctly. Also ring pack and selection is a must. First and foremost would be the extra skirt length but you should already be golden with the RHS block if i'm not mistaken. I'm REALLY interested in WHY your motor failed to begin with. To me that would be the most important first not? LOL

We will find out for sure, I have a feeling its gunna be something silly or simple. Its not if, but when we find out. All part of the process. Its drinking coolant and I do not trust it. So its coming out and apart regardless. Im just firming up a plan of attack here. Educating myself along the way doesnt hurt...

Its from July 19'. Oh trust me, I fought with my builder tooth n nail when he first wanted to use it. He said that was way long ago and only on a few high hp boosted builds. I was skeptical myself knowing the Dart aluminum block was well within budget. I dont expect to find that issue. He gave me a handshake guarantee on that matter. I havnt read or noticed any newer threads on that for quite awhile.
