Ld340 vs ld4b

Thank you for all your responses. I will go with the LD340 on my 70 340. I think the mechanical secondary 4779 would be more streetable? The LD340 does not look like a spread bore app. Still kicking around the 318 stroker with the 920 cast 273 closed chamber heads and the LD4B intake.
Thank you,
This is more helpful than the Maports sight...lol:shock:
