What? I'm sorry sir, but you are off a bit on this. Gilbert isn't close to zero in elevation, at least not in my part of Gilbert. The elevation here is 1,237' above sea level. As far as Basco's goes, I would NEVER let them change my oil let alone touch my motor. I can tell you first hand experience with that shop and ole Ray Ray and how they completely destroyed my numbers matching block and much more. Good luck with your motor build and hope it lasts, a better choice would have been WFO Racing in Phx. He does all of Cordes Performance Racing motors exclusively. Kelly over at WFO knows a ton about motor builds and also happens to race on the new TV show No Prep Kings which is a spin off from Street Outlaws. He will be racing his own car this season on that show. Kelley runs a Dart 800 cu in BB with 4 kits and looks like a plumbers nightmare and hauls ***.

I have a howards retro roller in my L-82 355:
219/225 Duration
.525/.525 lift
LSA 110
Operating range 1,500-5,600 RPM with
AFR 180's and 10.2:1 compression.
I have heard the same about the duration split with AFR's but can tell you my 355 has good bottom end, BIG mid Range, and strong power to 6,000 RPM. If there is a deficit using a split duration cam with AFR's, I would be shocked if there is any real world difference based on my motor which is monster for a SB V8 with 1 7/8 inch Long Tube headers. My builder who is an expert building GM V8's said the difference is VERY small and considering my engine should be in the 440-450 Gross HP range, i would never feel or note the difference on the street.
