Does it take a lot of work and tuning, yes.

Even in a "street car" (what is the exact premise? working PB, A/C-different thing to different folks)-My point was how many of them(11 second cars iron heads 041 or similar HFT) are out there vs very "similar" combinations that are in the 12s/13s? Walk through the pits at any big Pontiac race and I bet in the staging lanes the mid to low 11s car with iron heads and an 041 are very very few. Yes there are some like Jim and a few others that are there but a whole lot more in that 12-13 second class lane.

And if "new technology" is not as good why are so many guys running good even with iron heads and HR or "hybrid combination like Cliff's? I guess we need to kick Cliff and many of Dave Bisshop's combinations out of the discussion since they use that HR "new" technology. I'll bet 50 years ago they weren't using the coating Cliff is talking about experimenting with for a flat tappet try again either.

And for what it's worth my 78 TA raced in the old NMCA classes with first a 455 then a 400 with iron heads and the 400 had 4 cams some degreed in different spots , different carbs, intakes and header sizes and ran PB ,PS and A/C with most of the combinations and most were "modern" Ultradyne cams. So a lot of combination dialing in.
