6=8 and bore over?

Don't spend the money on Clifford stuff, it is simply not worth it.

PST Suspension kit with new shocks. (I tell everyone this from Slant to Big Block)
Aluminum Radiator
1 Wire Alternator
Get the engine running and driving well, Super 6 is a nice upgrade
Rear End!!!
Disc Brake Conversion

Finally... start to play with internal of engine

I chased the slant six dream for a while. It can be fun and was a great learning opportunity for me. That being said, when I got older and had a bit more money it became un-enjoyable. For the $3000 I spent upgrading the slant it was still a 16 second car. I would get the car running great and plan a 360 magnum from MRL performance or something of that nature.
