I am thinning the herd of parts I will never use so please let me know of any interest...a pristine LD4B for the 273LA that looks like new is offered to our list members. Chrysler part #2836139 on the LD4B.The Edelbrock LD4B comes with OEM cast water neck outlet, temp sender...killer manifold for the 273 & 318LA engines; looks like the LD340 in my Dart but smaller size runners to mate with the 273/318LA. I will send pictures if they don’t come through on this general email posting.Email or call me with any interest.Thank you!Gary Pavlovich
