Ford 302 V8 Conversion
This page is going to be choppy until I get things sorted out. Anyway, I did the Ford 302 conversion, I basically made it up myself since I couldn't find anybody else that has done the conversion. Yes it is true I did the whole thing for under $1000.
Main points of interest should be:
I had an exhaust shop do this, H pipe and dual glasspacks. It is true dual exhaust all the way back, and it even comes out on the stock place, so it looks as if I still have the 6 cyl with dual exhaust:)
I have a C4 3 speed automatic tranny in my Z. I am still using the same Datsun Tranny mount, all I had to do was drill two holes in it.
You have to get creative on this one. What I did was spliced both cables and welded them together, amazingly it's still correct.
Remember, the car was originally an Auto. so is the new tranny I installed, the linkage was a trick, because Fords linkage setup is on the opposite sides of the tranny than Datsun, so I disassembled the Datsun shifter, and ironically, the lever can be turned 180 degrees placing the linkage on the correct side of the Ford tranny.
The rear end holds up okay, but I burned out mine and had to get an R200 from a wrecking yard. If you do decide to install the R200 (mine bolted right up), I strongly recommend getting the urethane bushings for the mustache bar, and solid steel diff mount from Motorsports, otherwise your going to bust that rubber damper every time you give it half throttle!
Cost: R200 $60, urethane bushings & solid steel mount -CALL MOTORSPORTS-
This will have to be custom made, I had a Ford yoke & U joint in front, and Datsun U-joint & yoke for the back.
This was a direct match, it was so easy I don't remember how I did it. If anybody has any problems wiring up their Datsun, just e-mail me. I am using a Ford alternator, regulator, and starter relay, it does wire directly into the Datsun electrical.
Cost: Starter relay & regulator about $25.
Oil Filter Relocation Kit
The z-car motor mount towers will get in the way of the oil filter, so you will need an oil filter relocation kit for the 302. It was real easy to find and install, you shouldn't have a problem getting this.
I went ahead an installed the 4-row radiator from Motorsports to ensure better cooling. Although the stock 2-row did fine, but I live in a cold state (WA), I don't know if the 2-row will work in a hot state such as CA. I got 2 cheesy electric fans, because the clutch fan would not fit height wise. I have heard rumors that a radiator out of a camaro will fit(I haven't investigated this), which will save LOTS OF CASH!
Cost: radiator $235, electric fans $30
This is totally optional, I had one installed because the 302 was twisting the car pretty bad! This was done professionally.
Obviously I kind of went to extremes on the cost issue where I could have gotten things way cheaper. But if you only buy what you need to get the conversion done, it should come out under $1000.
