Carb/Manifold combo

Edelbrock carb and manifold packages seem to be the most popular option. I currently have an Edelbrock carb on a stockish manifold. I would like to add new carb and was considering the Edelbrock AVS and a matching manifold.

I'm looking for people's opinions on carbs and manifolds for the 283 with a cam in it.

Right now it runs good and I probably shouldn't mess with it but I want something better, new...

The car is a 62 Impala SS the 283, power brakes, power steering, and air conditioning.

If you are not winding it too high an Edelbrock 500 cfm would be ideal.

Unless you KNOW the fuel/air flow into the head is keeping your engine from it's full potential, I wouldn't change carb/manifold on a well running car.

Just funnin' with you a bit; all running engines 'have a cam". Depending on the cam, 'more' carb, better flowing intake manifold and better flowing cylinder heads may improve acceleration. But, only if mated to a complimentary drive train (see power glide comment below).

Does the car have dual exhaust? Adding dual exhaust will perk it up a bit.

If it's a power glide, switching to a manual (3 or 4 speed) will make a significant improvement in acceleration.

Just trying to be helpful.

What is your opinion of the 625 Street Demon carb with matching manifold.

I've found the best way to liven up a 283 is to replace it with something bigger. I'm building my 283 replacement slowly over time. Almost have everything for the short block ready for assembly. Now granted if I would have just went with a bigger SBC I would already have the engine built, but I'm opting for the "W" motor route which will cost 3X as much to build the engine and even more when putting it in the car cause it will need a new radiator, exhaust, fan shroud...

The previous owner livened it up with a cam and a rebuild. The only way the motor ever will be changed is if it blows up or I win the lottery. I want to get the bumpers couple spots fixed possible repaint. It currently feels like it hauls ***. It seems seat of the pants similar to my 97 Z28 when I had that.

lol, were two spark plugs not connected on the Z?


The 650 is too big for a 283. 500.

1996-'97 had available in the SS and the Z models an LT4 second gen small block Chevy that made 330 hp, but only 629 were made; the rest had the peanut port TPI 305 or a 231 cube V6 with a four cylinder Ford Pinto T-5 transmission and a four cylinder Vega rear end. They were not exactly famous for their power levels despite the LT4 being the fastest production car in the quarter mile in 1997. 1998 introduced the third gen small block LS-x and we all know what happened after that.

Sorry, Dave, your info is incorrect. His 97 Z came standard with the LT1, TPI was done in 92, and the base model was a 6 (NOT Z28). 4L60E or BW T56. The LT1 is actually quite famous for its power and torque, and is certainly much more than a 283.
