I bought a D8 head from the local scrap yard and paid something like 50 dollars for it. I took it to my machine shop and had them plane it down, and do a valve job, and fix a crack and replace the springs... ummm I believe the total was 200? and then bought the holley 2300 series 500cfm carb (paid 219 for it new and have heard alot of peopel saying its overkill so I would siggest the 350 cfm version) when I got it home I ended up buying an aluminum adapter for putting the holley carb onto a different car I dont remember what though... and the used a dremel and drilled out the 1 bbl hole and used a littel bit of epoxy to make for a good seal, and tapped some hole and mounted it all together, works great but I woudl suggest a header and exhaust and an electronic ignition, and a cam would probably help too... overall it was a bit of work but worth it I think I just looked through my pics and couldnt find any of the head before I mounted the car or any of the linkage, I will take some tomarrow if your interested...
