Hi,

I hope you can help me I am considering a new perfermance cam for my Tahoe 98, the engine is stock except for performance headers and I have removed the cat.

Can I use this cam ???

TFS Stage 2 Retro-fit Hydraulic Roller Camshaft SBC Chevy


Do I need to upgrade the injection system and cylinder heads too ??? Or will it work with my stock engine.

Thanks alot from Denmark, Europe.

Way too much cam for the injection, especially the factory black box ECM and intake manifold. Its also a retrofit roller and will not be needed unless you have a non-roller block.

You would need an Alex Spring/Retainer setup to run this cam on stock heads but IMO it would run well under the stock injection.

Thanks for the reply but mine is not the vortech engine I believe Its made in Mexico, Can I still use these Alex Springs???

 

What is the cylinder head casting number??? Reason I ask is I have run across a few of these Mexican built Chevy's here in Texas. IIRC they were called Grand Blazers or something like that. Even though the one I worked on was TBI, it still had Vortec heads and accessories on it.
