So you want 2 go Big block...Read this first!

well, i just got done puting a 360 into a slant six 74 duster. I did not put a 500 dollar junkyard 360 into it, i wouldnt waste my time. i built a nice powerful 360 with plenty of go fast goodies. But as far as everything else goes.....
300 for aluminum radiator(slant six has smaller radiator)
180 for conversion mounts
100 for aluminum bellhousing
400 for centerforce clutch kit
kept the 3 speed manual trans wich will break soon so figure 500 for rebuilt abody trans
250 headers
still have 7.25 rear but that will go soon so figure 900 for built 8.75 rear with 391 gears
250 upgrade to disks (9 inch drums wont stop a rev happy small block)
120 new shock
500 misc

you can do the math, this is not including the cost of the engine wich is well over the 3k mark

Your parts you put in are mor expensive than normal. My original post is for new...reasonably priced parts. I big block built like your 360 would prob cost $2000-$4000 to build in comparison. You didn't need to go aluminum rad with a small block..but for the long run, a good choice. and I think you spent too much for your centerforce clutch...I didn't spend that much, and thats what I bought for my car. $250 for headers seams high...What kind did you get? even still $3000 for a small block instalation...compared to $5k-$7k big block (if you had to buy everything)

I didn't make this post to try and have a competition with what cost more, or if it is the same, Or what. I wanted it to be a post that people could look at if they wanted to do a big block swap.
