Good results with 3.875" Stroke & Scat Pro Comp I Beam Rods!
Just posting this result because when I was looking, I could not find a answer. We used a 4.125" Bore Dart SHP block, Callies Compstar 3.875" Stroke crank & the 6" Scat Pro Comp I beam rods with the ARP 2000 upgraded cap screw. Minor Grinding on the Pan Rails & Excellent Cam Clearance for a standard base circle Hydraulic street roller. It turns out to be a 1/8" stroked 400 displaceing 414 cubes. The engine builder said it was a pretty perfect setup for what I wanted...a street motor, he said for drag racing, he would have done H beam rods. He also said because it was light that balancing was easy, he just had to drill, did not have use any mallory metal. The Scat rods I used were the Pro Comp series which seems to be very well liked by the people that use them, which includes a couple of big names. The part number is Scat 2-ICR 6000 7/16 A. I imagine this would also work well in standard 350 blocks to make a 396 Stroker this would give you 13 extra cubes over a 383 with the same money & a little extra grinding on the pan rail. Thanks & Good Luck!

No, I'm a putz! It's in long block form right now & I have to buy small parts. I kinda got side tracked with the 4 cam ZR-1's. I will finish it now. I just put the cam specs up so I could find them easier. Thanks.

Sorry for bringing a dead thread back to life after a decade, but I finally finished my build & in the sake of providing information for people searching for results, I am providing them, as there wasn't much info when I was looking.
Basic Build;
4.125" Dart SHP Block with 350 Mains
AFR 195 Eliminator Competition 75cc Heads with heat crossover
Callies Compstar 3.875" Crank
Scat 6" Pro Mod Rods with ARP 2000 bolts
530/530 @ 230/238 with a 112 lobe Hydraulic Roller(It was actually spec'd for a 396 SBC)
Weiand Stealth Dual Plane that was Exude-a-Honed to match the Ports
Barry Grant 650 CFM Mechanical Secondary Carb
Moroso Stroker Pan
Not a lot of Machining of the Pan rails with these rods.
On the Engine Dyno, the results are
560 Peak HP @ 5900
583 Peak Torque @ 4500
Ought to be a good street Engine, which is what I was going for. I know the Cam is too small, but it was paid for! Thanks!
