Have a 1954 TR2 with a TR4 power-plant [the way it came - wrecked] and did a frame up rebuild, installed HS6s... not a problem and I'm using the long neck intake manifold for added velocity. Got the HS6s at a junk yard, traded the Strombergs and a couple $ - got the rebuild kits from MM. Soon as I can figure out how to post images I'll try to select a few that will show you the layout. Oh, did needto crush the fwd air-cleaned a bit to clear the fendor but only a wee bit. See if that image can go on now... look at the bottom of the photo album.
