oil slinger - yes or no?
I don't have problems with belt alignment. And The slinger wont fit with a race cover. Also if you have probems keeping your seal in and rely on the slinger. You have other issues. I run methanol and Nitro. My new cover takes a o-ring. If your blowing your seal out you could go with a old cover they are installed from the rear of the cover.
Also a race cover is ment to be used with a after market damper , There is no tin dust cover. Like I said if you start adding reciprocating weight you would be surprised how it adds up. Even a fluid damper cuts initial reciprocating weight. The weight sits still and catches up.
Also no good damper has the slinger figured in on the measurement . Check them out if you have them sitting around as I do.
Also the fluid dampers are to be used with the 69 back pulley and no slinger on the 70 up cars. it acts as a reduction and puts them at the proper depth.
There are some that wish they would know and some that do. But every one has a cocky remark so I just don't answer them when they need something. Cutting off your nose to spite your face is common on this site.
