Right, the LD4B was the 273 intake, D4B for the early heads with the different bolt angle. We better not talk anymore about the intakes with Billy Nees on here watching.☺

Now you got me thinking about converting my street car (1969 Barracuda, 340, 4-speed) over to a stocker again. Since it is an original 340 car I didn't want to put a roll bar in it. My racer friends thought I was crazy wanting to race it without a roll bar. With the 160 MPH "Stockers" out there, they have a point. I figure the 318-2bbl combo would drop me down to R/SA where I wouldn't need the roll bar. If I put a roll bar in it, I might as well build a 383 for it. It has less HP than the 340 with basically the same AVS, bigger valves, slightly better heads, more cubes, etc. More weight on the nose though.
