Hey guys I made a list of everything I think I need, Im planning on doing a cam swap next month and wanted to be sure I have everything I need to buy, Still not sure on what cam to get but im leaning towards the 230/236, Any helpful comment are appreciated





LT1/LT4 Camshaft Swap Gasket Package
Comp Cams Hi-Tech One-Piece Chromemoly pushrods, 7.200" (OEM Roller - Factory Length)
Crane Gold Self-Aligning, Narrow Body Rocker Arm for Center Bolt Valve Cover, 3/8" stud, 1.6
Comp Cams 26918 Beehive Ovate Spring

Comp Cams "Extreme" LT1 Camshaft, 230 / 236, .510 / .520, 112LSA

also a electric W/P and clodes chain

 

first off i would get the pac springs

second i would go with some 7/16 nsa comp pro-mags with trick flow guide-plates and trick flow chromolly pushrods

 

Don't forget thread locker and gasket RTV. I like the Ultra Copper or Black.

 

Will stock heads with those springs take that much lift? Just thought I would ask since my seats were machined down to accommodate higher lift (that I am not using).

 

I was wondering the same thing, I will probably get some 1.5pro comps, with the 503 cam

 

I have seen an install on the web - I'll try to post the link - where the beehive retainers were not compatible with the Crane SA rockers.

Is this indeed the case?

I am very interested in this as I am thinking of a similiar install and I have a set of GMPP SA rockers- same as yours

 

That isn't a lot of lift at all. Duration has more effect, as I understand it, on PTVC anyway. You will be fine with 1.6 RR.

 

The 224/230 is my choice. Bigger is not always better.

 

I took it as a question about retainer to seal clearance, I don't know the answer though.

To get installed height with beehives you pretty much need longer valves or retainers/locks to raise the installed height. The later will cause SA rocker issues because it raises the retainer higher on the valve leaving less tip sticking out for the SA portion of the rocker to guide against.

 

I think this becomes the issue. Take a look at the link I attached above.

Can anyone else step in who has experience with the beehive type spring and SA rockers.......
