I'm in the process of getting my engine swapped from an 305 TBI to a 350 HO TBI. I finally gave into the recommendations of EVERYONE on this board and decided to swap the engine out instead of modding an L03. It says I need a 650 cfm to get optimum results. I also want to keep DECENT gas mileage. Which 650 cfm is the best to use?
The car is coming with vortec heads, so I'll need the edelbrock vortec intake, which I believe is square bored?

Thanks all,
Dave

GM Crate 350 HO TBI coming soon...

 

For fuel mileage I would definately run an Edlebrock #1406.

Last time I checked, and edl 1406 is a 600 cfm carburetor. I believe he asked about a tbi setup, not a carb setup.

Q-Jet, dual snorkel air intake, underdrive crank pulley, Hypertech Street chip, SLP y-pipe and 3" cat back with hi-flow converter, Edelbrock Performer intake,Accel ignition. Running better now.

 

hmm, the topic says carb help, but the message says tbi to tbi??. Sorry for interjecting my two cents, are you looking for a carb or tbi?

TBI, sorry. I need a new one for the crate 350 TBI. It says either a 625 or 650 for optimum performance. And thats what i want, a good 330 hp to smoke some bastard V-Tec rice burner
