what is a good size carb for my 351w???? A had a edelbrock 600 ready for my 302 but now that i have a 351 should i go bigger? because a have a holley 850

NO!!!! A 600 should be fine... I'm runnning a 650 on my car... More than that youre probably going to be washing down the cylinder walls with gas... an that is not a good thing...

An 850 would be too big, I dont remember the cfms per cubic inch ratios, but a 600 should be just fine.

ok thanks.......i was just kind disapointed because the 600 was brand new......and i didn't want to go buy another one

randy78045

Ha, i know how you feel... i have a 750 sitting in my garage...

850 is way too big for a 351. youll have the problem the dumbass in the white/purple hatch with no hood on pinks that was racing the guy named quick thats on here and be shootin fire everywhere. no wonder he could win a damn race. lol

i need a 750/////but 600 on a mild 351w or stock is fine..on a slightly radicle one a 750 is ok...

my 351w is going to be FAR from stock.....and hopefully supercharged....

Well it depends because your motors not going to run right with a huge carb on it so I would figure out how long its going to be before you actually get a supercharger and maybe just consider running the 600 until you do get it and than sell it and get something bigger for the blower... Im not too familar with carb'd setups so thats all the advice Im going to give. Good luck man.

I change my oil about ever 1000 miles and do oil analysis each time... fuel showed up in the oil when i was running the 750.. and i wouldnt exactly call my engine mildly modded... a 600/650 can go a long way.... IMO...
