Edelbrock LD4B

toolmanmike: I have a restalled stock converter. I am sure a looser one would be better, but I drive the car a lot when the weather is nice and its fine.

Mattax: Yes, that 273 intake looks like a 4 bbl version of the factory intake that came on this 318. Obviously, this 318 single plane was not intended as a high rpm screamer as it would only rev to 3500 rpm on the dyno-LOL. I've often wondered if they did them that way for hood clearance. My LD4B and Action Plus intakes are on the way. I'll be sure to baseline the Street Dominator that is currently on the motor before installing the other intakes so we'll have a three-way comparison. I'm very interested to compare torque production between the three of them.

It's interesting that nobody sells a small-runner low-profile single plane intake and claims its a torque improvement anymore.
