Hello all so I've finally installed my 2.02 fuelie heads onto my stock 350 it has flat top pistons with valve reliefs my heads are 2.02 fuelies with manely stainless valves harland sharp roller rockers comp cam springs and guides and are ported and polished also installed edelbrock rpm performer intake and 600cfm carb and comp can xe268h cam. Now my question is I have a Holley 750 with in pretty it has mechemical secondaries but it was rebuilt a year ago and just sat on my shelf in my room. Would that carb be more suited for my motor with the ported head and bigger cam? I also plan to swap the powerglide out and install a th350 with a 2400 stall converter or a 2000 to 2300 whatever I can find. Any info would be greatly appreciated thank you if you need any more info please ask.

I wouldn't use a mechanical secondary Holley with an automatic. Won't hurt anything, but every time you give it the gas, you're burning a lot of fuel.

I would reach out to Comp cams and ask them what they recommend based on your build. I assume the cam grind was matched to the flow characteristics of those heads.
EDIT**Check out this link from Comp about your cam and note the carb used. However, they are using Dart cylinder heads. Your cam

Nice the 3310 holley they used seems to be the same thing I have so I'll probably put that on then and get it tuned up. The edelbrock 600 i have needs a rebuild and the holley I have is good to go besides needing to be tuned. I am running the stock powerglide and rest gears as of now I have a master th350 I got super super cheap but idk the stall of the converter so I wanna order a 2500 for it. And rear gears I'll pribably go 3.55 the cars not daily driven anymore and I'm just trying to make power.

So I've installed my holley and got it running it needs to be tuned and timing needs to be done but it runs. I'm probably gonna take it to a shop to have it tuned after I install the th350 in the car. At the moment the amount of work I've done im disappointed with how it runs hoping the th350 and 2500 stall will help because it feels slower then it was lol. Which to me makes no sense.

So i may have found one of my issues why its alittle doggy the holley 750 is a vacuum secondary I haven't checked the vascuum yet but the brake pedal is alittle hard. So I assume my vacuum is to low. Will adding a vacuum canister to my car fix this issue
