225 Push rod length.

With those numbers you might be OK, but it will be close. Make sure to check. Also check valve to piston clearance.
PS: Whose cam is that? Looks like a Hughes number, but not listed on there website.
You are right, Hughes cam. (not listed, must be a secret stash:)) I ran some numbers by them and Dave Hughes came up with several cams for my application. I'm looking at this one (and a similar one at Oregon) as it will fit the machine work that has been done and my projected use of the car. I already have his valves and springs. I'll be doing a "mock-up" as Rusty had said, and checking in with you for some other things. I going to concentrate on building the engine vs the car itself, as the weather (cold) conditions control my work space. Maybe one day I'll enclose the entrance to my carport.
