Dang, the cost of this is skyrocketing as I research. I went from "I want to put a cam and heads on my mostly stock 440" to a full stroker rebuild after finding magic sparkles in the oil last month. 😂

I dropped off a good '78 440 block at the machine shop yesterday and spent 45 minutes or so talking to him about the plan. It's just going to be a street engine, no racing, and no need or desire for wild power numbers. I'll be sticking with 27" tires and an automatic, want to stay on CA pump gas (91 octane is the highest that is easily available) and most driving will be around 3000 foot elevation. I want to avoid breaking other stuff as much as possible and obviously spend less than more while still having a good strong reliable engine.

I already bought Andy's book, and this will be my first real engine build so I'll be here with lots of questions along the way I'm sure.

440 Source 512 kit and Holley SD intake is the only thing I'm sure on so far.

Probably Edelbrock E-Street 84cc heads so I can keep my current exhaust setup that won't work with angled plugs(or if I can find a good discount to drop pricing some, RPM heads and TTI headers would be an option. I wouldn't even be opposed to Trick Flows if I can find discounts, but I don't really want to re-do my brand new exhaust I paid 1400 bucks for last year, and I don't really need them for the power levels I'm wanting to stay at)

Originally I was planning on just sticking a Lunati 704 cam in my old 440 but now I've talked myself into just going full roller, machine shop guy is going to recommend some but I'm open to suggestions. I assume Harland Sharp are the recommended rocker setup. Any other lower cost but still high quality options to look at? All the other small bits and pieces I've got a pretty good handle on as it's stuff I've done before. Oiling system, pan and windage tray, intake, front end accessories, etc. should all be pretty easy or stuff I've got in the garage already.

The block I picked up also came with a set of 906 and a set of 452 heads, and the 440 in the car now has 915s on it. I'll probably throw all three sets up for sale at some point, as I won't have much use for them moving forward.

In doing more research, the E-Streets don't work with the cam I want and the price difference in RPMs and Trick Flows is so close it doesn't make sense to not go Trick Flow. I was really trying to avoid having to buy a new set of headers though. Stupid costs keep rising...The TF would raise CR higher than planned, but I should be able to fine tune that with gasket thickness?

I did order the 440 Source kit yesterday though, so that's an exciting step!

Cometic gaskets are the best choice & available in various thicknesses .
I would go to Lunati for the roller cam ,
I am not a fan of Harland rockers , I prefer to use Stainless rockers with bushings such as PRW , the needle brgs reduce the surface contact to almost nothing & what a mess if the rocker breaks & needle brgs take off

I built a 440 Source 512 for my 70 Chally many years back. It had Edlebrock RPMs and a factory six pack setup. It was a great on the street...not the fastest set up but very driveable.

Putting together a summit shopping cart to order hopefully early next week.

Which oil pump do you folks recommend? I'm seeing on 440 source they recommend high pressure rather than high volume for stock size oil pan which is what I plan to run. Or is a stock pump sufficient for a mild street stroker? The old motor has a high volume on it and I'm sort of wondering if sucking the pan dry like 440 Source said can happen is what I did with that one.
