I just installed an LD4B on my 318 (302 casting heads with a mild port job and headers) along with an Edelbrock 600 cfm performer carb and I love it! Lots of bottom end grunt and the gas mileage is pretty good too.

Last weekend I did a 600 mile road trip from Edmonton to Kindersly Sask. and back in the 67 Coronet with 3:55 gears and got between 17 and 19 mpg at speeds between 70 and 80 mph. The lower mileage was heading into a considerable headwind too! Lots of runs up to and over 100 mph along the way so I'm sure I could have gotten much better mileage with a lighter foot but wheres the fun in that???

If you ever want to open the throttle for miles on end then take a trip to Saskatchewan ... LOL

I'll start a new thread with the pictures I took along the way, we had an awesome day and I want to do it again several times this summer.

I got my intake from Tony at Tonys Parts (Moparts sponsor) for $100 US and I believe he still had another one in stock.
