It's not the original engine in my son's Barracuda, someone transplanted an early 70 318 engine in it with the LD4B intake...
For the 64 - 65 bolt pattern, the sister to the Edelbrock LD4B is the D4B which is identical to the LD4B, but with the old intake bolt configuration...
You could always swap a set of 66 and later 273/318 heads on it to match the LD4B...
Or a quick cobble would be to drill the intake bolt holes a little larger to give clearance for the older style bolt pattern...
The cleaner way is with the 66 and later heads....
