I run a Howards hydraulic roller in my 505. I like the quiet compared to a solid. Sounds and looks mild.

Drop in fit and zero issues with 5700 miles and hundreds of dragstrip passes. I limit mine to 6400 rpm.

It does what I need it to do without being high maintenance.

Runs low 11's n/a at 3,600 lbs.
