8Ba cam selection

I have the 248F, it’s a nice looking cam. While they were cutting it I found a NOS EAB cam. The 248F came with a degree card which intimidates me and makes me think I will have issues setting initial timing. I am used to setting timing with a stock cam using a timing light and the crank pulley and timing cover.

Cam timing has nothing to do with ignition timing. You'll set ign timing exactly the same way you've always done. If you don't choose to check cam timing when you install the cam, simply install it the same way you'd do a stock cam and it'll be just fine.
 
Yep - Cadillac512 has it right . . . the cam has nothing to do with ignition advance and associated timing (unless you install it wrong!). That cam that was recommended should be a great choice for what you're doing.

If you can, post the valve timing events from the cam card and at what lift they are measured from. Most of the flathead cam guys tend to show timing at .020 . . . whereas I prefer to see it at .050. Maybe the cam card has TWO sets of timing numbers?

The cam that he recommended is probably pretty similar to the 1007B . . . which lifts about .355 or so. Once I see the timing numbers, will know a bit more.

Funny how this stuff starts to snowball on you. I got the cam card out on the 248F and noticed it recommended a stiffer spring with a part number. The valve guy at the shop said that using the ford springs probably wouldn’t be adequate given the lift. Guessing new springs that are recommended opens up a whole can of worms with the rotator retainer and keepers?

Depends on whether the new springs are designed for the late rotator style retainers. Most are not, and require the earlier retainers with more spring installed height. Very important to get this correct.
 
It sounds like you have a good machine shop that knows what they are doing - that is great to hear as most shops can't even spell "flathead" these days!
 
3twinridges - do I remember reading you live in Georgia? If so, would like to know of this “good machine shop” Bored & Stroked mentions above!

I use Tommy at Goza Machine in Acworth, top notch. He does a lot of high end stuff but has a passion for the flathead.

Good to know JB. Thanks. Hope can meet up once you have your rebuild installed. Anxious to hear the 248F
 
Good to meet you Strick. I am up north of Marietta in North Cherokee County in the mountains but work at Perimeter. Some good shops in Marietta, ping me if you are looking for someone. Let’s meet up, I will have our 52 F1 in the Ball Ground parade, it’s one of the largest Christmas parades in North Georgia.
