Yet another carb question
Cars a 79 Z28...
Carb has an accelerator pump issue so thinking about replacing the whole unit .. 355 cu in comp cams xe274 -- .490 lift split duration 230/236 Performer RPM intake Aluminum heads -- 2.02/160 valves 200 cc runners -- springs set up for .525 lift 65K HEI with Accel ECU 1 5/8 headman headers turbo 350 with B&M Holeshot Converter (2400 rpm) 3.42 gears Currently has an Edelbrock 1406 600 cfm carb .. this is a fuel saving carb (not what i am looking for) .. Thinking I need something in the 650 --750 range with vac secondaries .. Is 750 to big or should I look for a 650??? Thoughts ??? Also any speculation on HP/Torque in this setup ???? Looking forward to your advice .. -Mike- |
If you're looking for a carb with good lowend and midrange response, then the vacuum secondary carb is a great choice. I like to go smaller usually, but the way your engine is set up a 750 wouldn't over carb the engine if it's vacuum secondary. A 650 would work, but not sure how high rpm response would be.
