I know,...there are many threads, video's and books about this very same discussion, but not by me.
Please note, that I'm not talking about top high performance, same cam specs or exact apples to apples, but debating a fairly mild 500 HP, costs vs power vs sound vs feel, is 21.4 HP worth the added expence of a roller engine.
Say, $250 flat tappet vs $1,000 mechanical roller.
Having to lash valves vs seldom.
Also weigh in on this question.
Working on engines is fun, almost theaphy, so I don't mind lashing my valves a few times per season.
This question shouldn't be in this thread, but is there a difference betwern your muscle car, hot rod etc vs your race car, in having to lash your
valve train ?
Or, to some it's a pain in the butt, so you have a buddy or a mechanic do it for you. No,...shame with that.
The guys on this video are split, and I am too.
What would change your mind ?
Is gaining 21 HP worth the added money for the sound and feel of a roller motor ?
No or yes and why ?
At what gain in HP is worth the expense, sound & feel ?
Doesn't matter, rollers rule !
Rollers suck and are too expensive !
What's your thoughts ?
