'Just wondering if FI like FITech or Holley when used with the 041 cam (no Rhoads lifters) tends to overcome the so-called driveability problems associated with these cams?"

Poor choice for a 400 build unless you have pretty high compression and plenty of converter/4speed and gearing.

Excellent cam for a 455 build but I still put Rhoads lifters on them especially if they are lower compression.

For the most part the 041 cam is too much cam for a 400 build. The engineers at Pontiac knew this and it was used exclusively on the RAII and RAIV engines. Every single one of those I've worked on over the years had very small combustion chambers and a lot of compression and they need it.

As far as the Crower 60919 cam goes, haven't used once in about 10 years but every single one that we purchased came with a cam card clearing stating 304/316 advertised, 231/240 @ 050", and 113 LSA. The recommended ICL was 109. Intake open point (can't remember that one exactly) but it was around 7-8 degrees BTDC @ .050".

At EXACTLY the same time the specs on their website showed the 60919 cam as having a 112 LSA and to put the ICL at 108 degrees.

IMHO at least thru 2008 when we purchased the last 60919 cam from Crower that they were buying SPC-8 cams from CMC and reboxing them. This is very common in that industry and still going on today with just about every single company out there making and/or marketing camshafts The reason I say that Crower was re-boxing those camshafts is that there was no advance ground into them and every single one installed came in around 112-113ICL, not down at the 109ICL they recommend on the cam card and website. If you go on their sight today they clearly state that "4 degrees advance has been ground into this camshaft" and that the ICL should be at 108 degrees.

So it's quite possible that 60919 cams currently being sold may actually be ground by Crower and not "re-boxed".......FWIW.......Cliff
