Another 416 Stroker Build-Pic Heavy
Ok , I was able to get it on the dyno and fired up today and not without some problems-mostly related to the customer's QFT 750 Annular. Why annular? I have no idea other than maybe the previous build seemed soft down low (which is weird for a 416) and he was told an annular booster carb would be the fix. I really don't know but I will try to find out. As suspected the annular boosters are over activated and this thing is super fat at the moment. It fired without issue and idles @ 1150 rpm with 10.5" vaccuum. It is very responsive to throttle input and should be with 240 psi in all cylinders showing on the compression gauge. It cranks 180 psi on the first pump. Tomorrow I get to dive into the carb and lash and possibly I can get ahold of his TTI large tube headers. That would be interesting to me. Hoping to improve on the numbers but so far I'm satisfied--it seems to be making about what I would expect for OEM heads. J.Rob
