Hot Rods Isky cam question

Does anyone still use an isky cam in their street 327-350 Chevy? I think it would be fun to run one but i just don’t see many new builds using an isky cam

Lot's of guys run Isky cams in SB Chevys. I'm not sure what would be "fun" about running an Isky over, say, a Comp cam, a Crower or any other but if that's what spins your crank then, by all means, buy the Isky.
BTW, I have a cousin that lives in Roscoe, SD................small world

 

I am running one in my 57 Chevy it's a Z-50 solid lifter. I like them and the brass timing plate that goes on the firewall.

Its a cam, and not that much different then anyone elses, They are just not hyped in Magazines or mail order catalogs

 

Take this for what it's worth...,

I've read over on the Ford Barn that the Isky flathead cams are prone to being ground out of spec. Don't know if any of their other cams suffer with this, or not.

Z55 grind in a 409, if that counts.

think you should file that under internet truth.NOT if one is off they would all be off as I am pretty sure they use a master slug if one was off they all would have been off common sense should prevail when reading something like that.

 

^^^^^ Bad timing gears would be the issue.

 

Also, there are two patterns for flatheads, and most, if not all, are ground to one of those. I can't remember if it is early or late, someone here will know.

 

...I use them in EarlyHemi builds.....no issues.

And Ford Barn doesn't know this? I didn't but that's because I don't mess with them.

Where does this shit come from ?

Early & late patterns would be the same .
Any difference would be the distributor drive method.

I run ISKYS' in my flatheads & vintage Cadillac's.

 

Early flathead valve angles are 49 1/2 degrees on one side, 52 degrees on the other. Later ones are 50 degrees both sides
