I made 755 rwhp with my old setup. Not 800, but close enough.

making 800 on 346ci can be done... just take me some time

making 800 isnt the problem, if i went from my current 200 shot making 700 rwhp to a 300 jet i would be close to the 800, or i could jet it to a 350 and make 800, but pushing water seems to be an issue around the 700-750 mark, and im still tring to get the car setup with 700. then i will jet it up

He means blowing a head gasket. I sprayed a 300 shot over 25 times on the same motor, never had a problem with head gaskets.

well, pushing water isnt blowing the gasket, when i say pushing water, i mean lifting the head and pushing a little water into the overflow.
every car i have seen making in the 700-750 range pushes a little water. the heads seem to lift just a tad, some times it does blow the gasket. Ive been lucky and i havent yet, but i did push water the last few times to the track do to a slight lean condition do to my fuel pump. she pushed about 1/2 qt of water, but we pulled the heads and the gaskets where fine.
the FI cars dont have that problem as bad because its a little slower of a power curve.
those l19 head studs (or somthing like that) Chris from APE could fill you in on that. seem to have a higher streangth, and they might help a tad.
my car pushed a tad over 700 with a 30 jet which is around a 250 shot with my kit, and it was ok on the dyno, i run a 28 jet now (200 ish) and on the dyno she was fine, but at the track my fuel pump couldnt keep up (thats why i did the stand alone) so she ran a little lean and pushed water. im keeping the same jets this season for a while, i'll see if she still pushes with the stand alone.
