SBF cam swap questions

[stephen low]

So guys another query, this regarding a proposed cam swap on my Windsor.

Have been planning to do a cam swap for a while using a new unused E303 cam I've had in storage. The standard ECU can't even handle this mild cam change, so a Motec install needs to happen in parallel.

However on the cam change, first question is whether this can be successfully managed with the motor still in the engine bay? Anyone successfully managed an in-situ swap?

So tearing the top of the engine apart to pull out the cam followers prior to cam removal, do I need to consider replacing the followers or should these be ok to reuse? Not sure about the pushrods either, suggestions?

The car is running edelbrock performer heads and am led to believe the current spring ratings are fine with this mild E303 cam, as lift changes are not overly aggressive.

So hopefully without needing to do an engine pull, can anyone identify the range of engine gaskets I'm also likely to need to replace during the rebuild?

It's been several lifetimes since I've seriously pulled car innards apart but with the right advice and parts I shouldn't get too far astray.

Would appreciate more brains trust advice again.

Cheers

Steve
