Going with the electronic ignition. Going with the 16" tires and after much dialing I've chased down a guy fairly close (100m) who is willing to do the rear end swap for me. I'm meeting with him over the next couple of weeks to let him have a look at what I've got and determine what he can do for me.
Following up on the 4bbl, I've seen a couple of suggestions. Holley 4160, Edelbrock 500 and a Holley 390. If I'm looking at a Clifford 4bbl intake... is the Holley 4160 overkill for the 235?
