66 292 to 350 swap questions

[Bushman66]

1. What side to put the dipstick on? The Gen 1 350 Chevrolet crate motor has the option for either side.

2. Will I need to shorten my Z-bar for my clutch? Keeping the factory 4 speed for now, I have a new (OEM-style) clutch kit to install while I'm in there.

3. I plan to use the 69260 Hedman street headers. Any issues with these?

My plan is to hang some cheap turbo mufflers on the headers for initial startup/cam break in of crate motor. I'll also use the points distributor for now, when I replace the factory wiring, I'll upgrade to HEI.

4. Any other tips/gotchas, things to check before first firing? I've done engine swaps in the past, but this time, I'll have a brand new engine that needs to fire immediately so can't afford to miss anything, miswire something, etc.

Thanks!
