looking at buying the hardin marine cyclone shortie headers they are direct replacment for gill manifolds and my gill riser the tall long riser will bolt right on, with the 741 cam will i have any reversion problems, is the 741 a 112 or a114 lobe.

Thanks

The 741 cam has a 112 lobe separation. When you say tall long are you referring to the HP500 riser? if you would like to email me a picture of the riser I could be much more specific.

rssteiny ..... the cyclones are the same setup as the Gils ...right? .....seems if you did not have problems with the Gil Manifolds the Cyclones should be ok? What does HM say? Are your tail pipes the long ones with the Dumps at the end? I have looked at the Cyclones too and look like a nice setup to get away from the Gils ..... Keep us posted !!! m

Here is what i have they were on my 2000 hp500 with no problems with the gills and the stock cam, now im using a bigger cam and dont want reversion problems, these dump out about 3" from the end.

This is what I run with a 741 cam and have know problems and hardin headers.

Are they the cyclone shorties and gill risers,, sweet looking ser up

Jeff P31

Yes they are , and another bonus is life is a lot easyer when changing the plugs compared to the gill's.

acaruso

thay suck same problems as gills REVERSION that is why I sold you my tail pipes Ilooked into them VERRY POR WELDING

rssteiny

So what do you suggest for exhaust

Another solution is to have a small (1/2") angled dam welded into your risers. have it welded in farther in than where the water dump holes are.
