Sure, but in my experience their suggestions are inaccurate even for a 440. Looking for real world experiences with pump gas RB strokers. I have done a 416 smallblock with roughly the same compression (10.5) as this 499 project, but it was in a 3100lb Demon with 3.91 gears and a 3000+ stall. The SB strokers tolerate cams pretty good, I had a 259/263-110LSA Ultradyne solid in it, which idled choppy but was real streetable in that combo. I was hoping to roller cam this one and pull off the 3.23/2500 stall setup. Thanks!


Just a guideline for sure. Well then, here`s my real world "ISKY" experience.......470 low deck, 12.1.1 comp..680-.660 276-281 @ .050 108 lsa solid roller in at 104+ 4.10`s and 9.79 first pass off the trailer but WAY different than your combo........


Oh yeah! I love Isky stuff, BTW. I built a flat-top 471 B for our FED rail dragster and with Eddy heads (fully ported) and a Racer Brown 280@.050" with .660" 108LSA roller it runs 7.90s with a 4.30/Powerglide combo. Tunnel ram with 2 x 850s on gasoline and zoomies! This 499 street motor is hopefully going to be done around 5500rpm with the RPM intake and standard port heads, so I gotta make myself "undercam" it.. HAHA
