If you want to put a blower on it, I would plan for that now and put rods and pistons in it. It can live at low boost with the ring gaps opened up but the pistons will fail if you try to run 15-20 psi. Really don't know what a safe boost is maybe 10 psi.

I'm sure a power steering pump off an eagle car engine will fit. The mds will need to be deleted with lifters and plugs. They make cams for the vvt engines so you can use either one. Eagle heads on early engines have alot of compression.

I have not used megasquirt, I had nowhere to put the computer as it can't get wet. I use Holley Terminator X, The X Max can do drive by wire throttle.
