Well I got out a can of starter fluid and started spraying once I got it warmed up. I can go all the way down the drivers side head and around the carbs with no increase in rpm. Then when I go to the back of the passengers side right below the coil the rpm will go up a couple hundred rpm each time I spray around there. I also hear a sound which I thought was an exhaust leak in that general area but I am thinking it must be an intake gasket leak. Would that normally make a sound like an exhaust leak though? Definetly something not right back there so looks like the engine builder did not get the intake on correctly and now we will have to pull it. Anyone have any input before I crack it open??

500 cubes/stealth heads & it ain't been right since day 1 with the massive intake leak. With a killer eng like this you're gonna have a smile on your face once you get it sealed up/tuned
You think OP, once you get the intake sealed up try setting the outboard linkage up on the center carb. by screwing each end rod out longer than needed to insert it into the linkage on the center carb. Then adjust each one of those so they just fit with the outboard throttle shafts closed all the way with the idle speed screw on the center carb. backed out all the way, adjust from there One other thing is to check the idle mixture screws on the outboard carbs, remove the lead plugs if neccesary and adjust them in all the way carefully,do not FORCE THEM in ,then adjust them out 1/4 to 1/2 turn each on both sides. set the center carb. mixture screws from 1 1/2 to 2 full turns out from bottoming out also, then set the idle speed off of the center carb. My last six pak idled at 850 RPM in gear with a lot bigger cam than yours, it took some tuning to do that also You can make it work good also

Since I am going to have it off the engine anyone have any input on what jets, squirters, secondary springs, and pv I should put in since I will have it off? I know I should probably seal up the intake first but since I will have it all off on the bench it would be easy to do since it sounds like it will need something a little bigger. Thanks for all the help guys.

If it is a stock 6-pack set up I'd jump to 70 jets, 33-35 squirters, maybe drop down on the PV also, not sure what type of vaccum that cam should pull. I have yet to change out my acc pumps but I've been to told go up to 50cc. As for springs, try it on the street 1st. I eneded up with the purples and it flat out hauls tail. Once you get it tuned hang on.

brand new remanufactured carbs
Are they an original set that has been rebuilt? Or are they brand new? I've seen some sets of 1969 originals that had the "kill bleed" holes drilled oversize in the outboard carbs which prevents them from opening with vacuum.

going to pull the intake tonight, what should a factory aluminum intake be torqued to? I will use a small amount of black rtv on both sides of the gasket should I use sealant anywhere else to be safe? Thanks

I dont really like RTV on the valley pans, usually use copper spray on them though, just some RTV in the corners where it meets the block/heads.
Since you've got a leak though you may want to consider something. Are you using paper gaskets in addition to the valley pan?
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

Wow. My experiance suggests that you'll be pretty close with stock jetting. Hard to imagine that you would need 70s (comes with 62 or 63) in the center unless you have the mixture screws on the outboard cabs nearly closed.

each motor is different. don't think just because everyone says to run 16 to 18 intial and 36 to 38 total is correct, this is abunch of b/s. my 383 6pk loves 22 inital and runs great with48 total. i run 70's with a 33 squrt, point is find out what works for your gig. standard usual b/s can be a baseline and thats all. i'm not saying that there aren't issues at play here however, there is a correct starting point and then work from there. i'll see if i can get you this tech archive but ANYONE on this site that has a 6pk has read this article, it helped me a bunch. can't figure out how to link the tuning info to you. get a hold of DAYCLONA, member here, he is the one who posted it, great tuning info, follow it step by step. hope this helps.
