Or I should say id like to put another 700hrs on it myself

Mcollinstn its a 1050 holley carb but ignition is all stock

So is there not a good cam out there that I can install with out doing any machine work or is there no way around this

You can use the Gen VI cam in your Mk IV. Just need to get the retainer plate thru GM. The block "should" already be machined for it. I'd be surprised if it isn't already. Use the Gen VI chain set.

That's the link to the GM chain set and includes the retainer plate. Some have said they needed to elongate one of the bolt holes in the plate to use it on the MK4. Some will complain it's a single roller but it's plenty strong and durable.

So there isn't a direct replacement performance cam for this engine
