looking for intake carb / manifold recommendations for 318 1973 La block
It may need tweaking, right? Just saying. I agree its a good deal and work well with his combo.
Previous guy said it was too much carb. That carb should be able to be tuned to any v8 to work well.
MAY need tweaking is correct. Rods and jets for tuning is the most it’ll need. If any linkage is off from what it should be set at, this information is readily available and easy to adjust with simple home tools. Worst case is a trip to horrible fright for a mic, pliers, needle nose pliers, flat tip screw driver.
I don’t know why the seller felt it was too much carb. His opinion? IDK. I’ve bolted down big carbs on small engines before and it’s all in the rod and jet for Carters or just jets for Holley. Adjust the pump shot, jet correctly, your done.
The 318 normally came with the small primary TQ if not always. This is a factory move to prevent issues in the extremes that some of the general Joe and Jane public will find a condition it won’t work to their expectation. Scenarios like, it’s cold outside, I pumped the gas pedal 50 times and it won’t start.
Cars starts, I floor it in gear, it drive like ****.
(Mechanic) Did you warm it up?
Owner - No! It started right? It’s good to go, it just sucks.
i'll echo what others have said here: intake wise a factory 4bbl or aftermarket dual plane 4bbl like the performer, weiand or offy would be a great choice. pair that up with a carter afb/edelbrock 500~650 or an AVS. throw a factory electronic ignition at it and you'll be rocking and rolling.
that would be about the most reliable, low lift, inexpensive, easiest install you could do. TONS of parts new and used.
Another dual plane I like is the older LD4B or a Weiand Action Plus. No coil mount for the Weiand.
