Hi guys i just thought i'd share this with you all, i'm putting together a Yblock for my 32

running twin 4's and a normal valley cover wont fit so i made this one out of S/S it's fixed to the block by M5 set screws around the perimeter, cheers oggie











y block powered mudshark or atomic

Thanks for the engine picture.  Looks good.  I still think you have a problem with the front carb.  Do the power valve pistons work freely up and down?  I'm assuming at this point you've checked the base of the carb and the adapter itself for any vacuum leaks.  If all else fails, then I would swap the carbs so the front one is on the rear.  If the problem goes to cylinders 3 & 7, then you know it’s definitely the carb.
