Motor advice needed

It is finally cold enough in the garage and i have some time so i have started working on the boat. I am doing motor work now(thread coming soon), and am ordering parts. I have some GT40P heads, ordering a weiand stealth intake, 4160 rebuild kit, gaskets and head bolts and other misc items

Just wondering if the DUI distributor/wires are worth the ~$500.

What about a new cam. Not sure i want to tear into the motor more, but it is also out. Figure $250 for a new cam and lifters, could probably reuse the push rods.

Also, how do you break in a cam and set the timing? Seems like it would be hard to run it at ~2500 rpms and varying the rpms and get the timing set. Do you just set it close enough, break in the cam, then set it to whatever it is supposed to be?

Anything else i need to order?

I have been using the automotive HEI distributors found on eBay seller theswapmeetparts (24237 . You will have to remove the vacuum advance, install a vent and re curve the advance weights but for $99.00 with wires its well worth it . You will also have to remove the pin on the cam gear and let it float. I have been running them for years on three different boats. They work perfectly. Let me know if you need more information Mike 678-227-8833

Consider if you clock the lifers and rotate the engine 20 revolutions before putting on the intake, you can verify all the lifters are rotating, or not.. Then with more certainty the cam will survive break in, or correct the issue immediately before damage occurs. at startup

I'm partial to a pertronix igniter triggering an MSD box and blaster 3 coil

I take your engine is std rotation?

That cam seems a good improvement without being too much , i'm running similar lift at 214/224 duration

However you should do some thought about running roller cam valve springs with the flat tappet cam. that said many have done it successfully without issue.   You may want to measure some spring pressures and make sure its not too high, and of course oil additive.
