Re: Anyone use howards cams?/heard them run?

I am running a Howard's 110961-08 it would be the next size up from yours.

Also Howard's #98212 valve springs (115@1.780″, 340@1.250″) with offset keepers and valve rotators deleted. Ye Olde "Z/28 springs" would probably have worked fine.

Mine is a 285 advertised duration, 231/231@050; 470/470; 108LCA; 104ICL

I am running 10.9:1 compression, 2500 stall converter, and 3.73 gears with a TH350. It has enough vacuum to "adequately" run power brakes. The Rochester has been heavily doctored via Cliff Ruggles book, and I'm running a 5inHg power piston spring. The idle air passages have been hogged out significantly to try and keep the throttle plates closed enough.

I'm getting 10mpg, which isn't at all bad, considering what it is.

The cam survived break-in, and hasn't lost a lobe yet in over three years of daily-driving. I currently use Shell Rotella Diesel oil and a ZDDP additive.

I'm a big fan of 108°LSA. The idle brings peace to world. I call it "Potato Therapy." Just a minute of idling in the parking lot at work, and I'm ready for my day. Fire it up to go home, and I'm at peace again.
