Sorry to beat a dead horse if this has been overdiscussed but my searches turned up little info. We apparently wiped #4 intake cam lobe and are very seriously looking at the Ramjet 502 as a replacement. Mainly due to ease of installation, tuning, and hopefully a very reliable engine. The car is a 1970 chevelle that currently has a 454 and a turbo 400. The 10 bolt 3.73 posi will get swapped for a 12 bolt 3.31 posi before the engine install. We will also be adding headers. It looks very straight forward except for the fuel pump. We have a fairly new tank and it doesn't have baffles, and a good solution is proving elusive. Anybody got ideas, tips, suggestions, or experiance? I know we could have a fuel sump welded on the tank but we would rather not. Thanks in advance!

I have a 70 also and installed a Ram Jet in my convert. I am installing a fuel tank from a Buick Grand National which fits perfectly but is not centered under the car due to the location of the spare on the GN. The lack of baffles will cause numerous problems with the stock tank if you use an in-the-tank pump which is the way to go for street use. Feel free to e- mail me for more info.

I didnt do this to my Elky (still has a carb) but I have a sandrail that has fuel injection with a spun aluminum tank (no baffles). Talk about sucking air on the side of a dune! What I did to correct it was installed an accumulator tank (which you could do in the engine bay) and have a seperate fuel pump that pumps fuel from the main tank to the accumulator(top) with a return line(top) back to the main tank, then draw your fuel for the fuel injection from the accumulator tank(bottom. This keeps fuel in the accumulator tank at all times because if the main tries to suck air it is only for a short while and the accumulator has enough fuel to cover this timeframe. It works great in the dunes where the problems are much greater than on the street. A small fuel cell( 1 gal or less) in the trunk should work just as well.
