Re: Reversion what is the impact?

Mike,

Your 388, does it have knock sensors? Is it a Mercruiser or GM ECU? I am being told that the ticking noise from the Rhoades lifters closing the valves faster may be missdiagnosed as engine...

Re: Reversion what is the impact?

Mike,

The Crane web site is far from complete I have found. You have to call the Crane Tech line to get the timing card for this cam #. The cam is essentially the EFI500 so not huge but big...

Re: Reversion what is the impact?

The 496 do not come with headers. They have an aluminum (Gil) exhaust manifold exiting into a 3" SS collector inside a 4" dia SS water jacket which is rather short. Probably could extend these...

Re: Reversion what is the impact?

Knowledge is sure what I am here for.

Yes the bigger the engine CID the more sensitive to reversion is what I read.

When you brought up the Rhoades lifter option I started another thread just...

Re: Reversion what is the impact?

Re: Reversion what is the impact?

Did you run this cam and get reversion before installing the Rhoades lifters or did they go in when the cam went in? If you did get reversion without the Rhoades lifters how much did these lifters...

Re: Reversion what is the impact?

I just talked to Rhodes. No they do not offer a V-max lifter for the 496 but.... they will convert your existing 496 lifters to the V-max for $95. There is some question as to if the current push...

Re: Reversion what is the impact?

Unfortunately I do not see them listed for a GM 496. The 454/502 lifter will not work because of the different oil galley in the 496. I think Crane and Morel are the only sources for the 496 lifter...

Re: Reversion what is the impact?

That is a very interesting approach to dealing with reversion. Do you know of anyone else that run these to control reversion? Thanks.

Re: Reversion what is the impact?

How do "shutter's in the exhaust" work to prevent reversion?

What is a " cam doctor"?

Re: Reversion what is the impact?

Re: Reversion what is the impact?

Thanks as always for the information Ray.

Just to make sure I understand you, the LSA on my cam is 114. I thought that a given physical cam can have only one LSA. I am unclear about your meaning...

Re: Reversion what is the impact?

Is a higher LSA number or a lower LSA more of a reversion problem?

What would be the reversion potential of LSA114 degrees in your opinion?
