intake casting # ID please
 

My son's 2bbl on the ole 350 is now junk. We have the Edelbrock 1406 ready to go. I have 2 cast iron 4bbl intakes to choose from. One is 3965577 and I think it's off a 69 or 70 350. The other is 340234 (340284?), unknown.

Both are identical except for the way the 4bbl intake is cast. Both are for q-jets but are slightly different.

2 ?'s:

1. What are these from?
2. Pros and cons, which would you use?

On a budget, just using available parts, not wanting to buy new intake.

Thanks

CP,

My book says 3965577 is from 70 Corvette, Camaro, 4 BC, cast iron, 300 & 350 HP.

The closest to the other one is 340281 - 305,350 82-85 pass. or Camaro cast iron Q-jet.

or 340261 - 340261 350 74-76 pass., Camaro, Chevelle, Nova.

I think the first one lends to higher performance. Just my opinnion.

you ought to snag a stock aluminum intake off a 80;s air conditioned car like 870 caprice, etc, they are 4bbl 305 engines, i like those intakes on mostly stock motors, they stay alot cooler and are so light and easy to set on engine under hood.
i have three of them lol, i snag them when i can.

good luck.
