Built 355 not what I expected
Someone please try & help me,here's what I have,30 over 350,10:1 flat tops,292 comp cam ( 501 lift ) Edelbrock Rpm intake,msd ignition,hedman headers,demon 625 carb,40 series flowmasters,Edelbrock heads 64cc 185 runners,the problem that I think I have is maybe I overestimated what kinda horsepower I would have,I'm still running 4l60e with 2500 stall & 342's in the rear,the damn thing just doesn't seem to have enough umph !! Any ideas ?? Thanks !!!!

It does seem a little rich,I wasn't running a thermostat so I put one in yesterday so it would be fully up to temp,started both mixture screws @ 1 1/2 turns out then slowly turned them until it changed the tune them backed off till it smoothed out,wasn't as bad as far as running rich but I think it should be stouter than what it is,kinda let down as I have a lot of money & time in it

Sometimes those flat tappet cams will flatten out if the lifter bores are sticky or if the cam wasn't lubed well enough on first start up. Does it feel like it runs smooth when you floor it or is it kinda sputtery?
