It appears by your description to be what I call a "mail order parts engine".....
the edelbrock parts are not bad, but they are not that great either...for the price you can do much better. The Scat crank.....IMHO, I would not touch one.....they originally started off building VW cranks etc.....now many high end racers use their products (promotion for sure) but the parts they use & what you buy are 2 different things....if you check Ford racing (and others- similar), you will not find any engine using a non-forged crank (stroker) but Scat sells these kits left & right.....others who have been in the business for decades will not sell non-forged units either (in 90% cases) such as Crower....hank the Crank was the oldest crank builder in the business.....forgetting more than most will ever know...non-forged cranks for any stroker were not even an option in his shop & he started in the 40's eventually retirng & selling his shop in the late 70's.
and the cam.....
Comp has by appearance - seems to be a company that has experience more cam lobe failures than most and places the blame on the low ZDDP in the oils. Is it a factor yes, but I highly suspect that they are also using Chinese cam billets & they do not include Parkerizing their cams (Parkerizing is the final step and a crucial step to help break the cam in- a heated acid bath that microscopically etches the metal surface and adds a very thin layer of graphite coating which allows the cam lube to hang onto and penetrate into the cam surface during cam break in) unless you specifically request and pay additional money for it. If someone ever tries to compare advertise specs of a cam to another, it is really impossible because advertized lift/duration/lobe separation is just that- advertized and not the specific grind including ramp profile that is used on the cam.
That is why I highly recommend Iskenderian & Crower & Chet Herbert & Lunati...all are family owned, been grinding cams for decades, and both will even re-grind your oem cam if possible- saving you even more $. As an example of the QA differences, Isky inspects & test every single valve spring befor it leaves the shop...Comp, well it is cyclic the complaints that you hear from machine shops...it goes from bad valve springs, poor quality retainers, cam lobes suddenly having excessive wear (many reported as soon as 10,000 miles). Comp is a mass production high volume operation.....for the same price, you can get a complete (or your machinst can purchase) cam valtrain assembly that is hand selected for your engine & application by one of the family owned/operated cam companies.
Given the criticality of the component, when it comes to making an engine breathe, there are so many variables including elevation, humidity, fuel blends/available octane, most cam mfgs will vary a "core grind pattern" to match the external impactors in addition to the internal impactors- which today IMHO makes the different between and engine that runs well, to one that just seems to run a little bit better, smoother and gets better mileage than expected.
While the price for a stroker build in general is about right, for the same $ you could definitely get an engine build with a higher quality of parts.
