In 2014, I pulled out a fairly stout cam from my 440/493 because I was looking to make the car more comfortable on the street.
It was a Lunati solid flat tappet with the following specs:
I was using the same 1.6 rocker arms that I still have.
I had it installed 4 degrees advanced and degreed. The car ran really strong. It actually had decent manners too. It was the idle quality that bugged me. At the time, I was running a 727 with a loose feeling 10" converter built locally. Part throttle performance was soggy. I also had a Gear Vendors overdrive unit and coupled with the converter, freeway performance was soft until I floored it. The combo was great at WOT but felt loose at any other time. I didn't like the shakes at idle in gear so I set out to smooth out the rough edges.
I pulled the GV overdrive and also changed to a better quality 11" converter. Drivability improved at part throttle and cruise but the shaky feel at idle in gear still got to me. I later switched to the Mopar Performance 284/528 solid cam.
Idle vacuum went way up. The idle in gear is much smoother. Power is good but noticeably lower than before.
I'm looking to do a conversion to the popular Tremec 5 Speed. This got me thinking.
I saved that Lunati cam and the lifters are in order. It is very tempting to swap it back in to get back to that snappy performance. The Tremec trans will mean I won't have the "in gear at idle" shakes.
The compression is approx 10.17 to 1. I have ported Edelbrock heads, RPM intake, 2" headers and have 3.55 gears in but also have some 3.91s I can use.
I have heard that a manual trans allows you to go a bit wilder with the cam and still have decent street manners.
Opinions?
