After a long wait, (core shortages) I got my cam set today...Let the weekend begin!
Sorry about that, looked good on my end, so I'll shoot a new one.I just can’t quite see the cam card clearly.
Inquiring minds wanna know!
Something that is a first for me, (but it wouldn't be the first time I've come across something that has been a common practice, but new to me) in the installation instructions, "if you are using double spring assembly, along with a flat tappet cam, you must break in the cam with the outer springs only. Assemble the head with the outer springs only until break-in is achieved."

There is a another thread on this forum about 1.6 int/1.5 exh rockers.
Notice this cam has 4* less exh duration.
Yes it is, I talked to the folks, (Dave and James) told them what I was doing and what I was trying to achieve with what I was working with. Everything...Carb, Manifold, head work, valves, pistons, No2, drive train etc. and how the car is to be used. Also I have had a tremendous amount of help from the members here on the forum especially "Charrlie" down in Florida. Hughes came up with the numbers and had the grind made for me.I don't see this grind on the hughes page is it a special grind for you?
The 170 is a good motor. I've watched a lot of Uncle Tony's stuff. I had originally started to build a tricked out 273, 4 speed etc. accumulated it all, (still have everything) then I figured, what the hell, everyone does a small block, so why not the /6, to be differen't. Have some fun with a "sleeper."yeah. i've talked to charrlie several times about my build which will be a 170 slant some people frown at the thought of building the baby motor . but i like it short stroke. and uncle tony from tony's garage said it is a perfect engine to build.. kinda figured it was a special grind..lol
Since when is 110deg "not much" lobe seperation on a quick rate of lift 220/[email protected] cam? Why bring Rhoads lifters into this thread, full of mech cams? The theoretical lift will not be realized, l was hard-pressed to achieve .470" with a .490" design lift on the intake.That is very high lift and little intake-exhaust separation, so will idle poor and rumbly, unless you use Rhoads leak-down lifters (not for solid lifters). Likely not much intake vacuum to operate a brake booster or climate doors. Those look like high-load valve springs too. More for racing than cruising.
