I have the very same Comp cam in my 505 RB 68 Cuda.
Victor intake , 950 Holly , Cnc'ed Stealth heads . 11.2 - 1 compression , 440 Source 505 kit
I wanted a rumbling idle in my Cuda . The big cubes will smooth it out a bunch . My engines not together yet , but a fellow member on here sent me a video link awhile back with a 500 CI with this cam and his car sounded very good , but not radical. But still smoother then I expected for this whopper of a cam .
Im also running 3.73 Dana 60 , drag radials with a Dynamics converter
