Still on Vacation, but have a few minutes to post reply. I will try and answer these questions in one post
Crank is a SCAt 9000 cast steel 4.00 stroke
4.25 stroke in a SBM to me is a very Bad idea, longevity will suffer. You will either have a real bad rod ratio or a piston with no skirt. Rod ratio does make a BIG difference if the rod angle gets to bad, it will try and put that rod right thru the side of the block
Drivability is about the same as the CC
Did not run a carb, but the best carb combo made 520-530
This build is not for everyone. And its not a Simple put it together build either. There are things done to this engine you don't see and will never get in those cookie cutter "crate" engines. Not to mention they will not make this kind of power with this kind of drivability. The list of things this engine meets to make it streetable is not one I made up, but from talking to you guys, HUNDEREDS of you over the last 20 years or so. This is what a lot of you want. It has taken me years of tweaking, applying new processes and products and many MANY hours of dyno testing to get this combo where its at. Is the most powerful thing out there? Hell NO. Can it make more? Hell YES. If we were to swap the hydraulic roller for a solid roller this combo would make 600/600+!
Cost for THIS build was in the $12-$13K range, depending on options. Complete from T-Body to oil pan, entire EFI system with fuel pump/system, dual sync dist, Dyno tuned and ready to Rock! Yes its a bit out there in cost, but this is not your Standard SBM build. I am proud of this build, it hits all marks and is just a sweetheart of a runner. When I get another Mopar this is what Im going to build and put in it for myself!
