I have only had one problem with this set up. The MSd was bad would not let me rev over 7200 prm. Other than that. My motor had ran perfect. I do run 110 fuel at all times. My head gasket is copper and the cylinder has an O ring installed in it
Entomer..Just so you know. when i put my ds on the dyno to find out what was wrong with it. I was making 65 hp at 7200 prms. I would call that a very big improvment over stock.
I do need to go back to the dyno and see what i can get now that i shift at 9000.
Ok thats my 2 cents

There was a dyno shoot out a few years back with some major V-8 engine builders and one of the rules was 93 octane pump gas would be run as an equalizer. I was quite amazed at the compression ratio's they were running. So I started studying to find out how they were doing it. I found out cylinder pressure is WAY more effective than static compression. The builders used giant camshafts and ports for high rpm so they could make good horsepower and figured out they were giving up hugh amounts of cylinder pressure because of duration so they started bringing up the compression. Even on pump gas one builder was up to 15:1 compression with no signs of detnation. Most of the other builders were around 12 or 13:1.
Compression is what everybody talks about but cylinder pressure is where the horsepower is at and the way you get it is with porting and camshaft timing. I can make way more cylinder pressure with a good port job than by putting a high compression piston in. Now give me more compression and I can give you better cams that will make power higher in the rpm range. IT'S ALL ABOUT MATCHED COMPONENT'S!

Hahaha,hehehe,lol,lol,lol! Yeah, that is funny, I dont care who you are. I like that. We will see how much sand you (THEBIGSHOW) can sling at the spiderbucket. Its gonna be kind hard to fill it up with sand when your running behind, [img]i/expressions/face-icon-small-wink.gif[/img]

720 Big Bore blown head gasket
O-ring your set-ups and blown head-gasket failures will cease to exist unless you go wild with power additives or have sleeves moving around, the mls cometic is a good short-term fix and may last some builds a good while, but if the ponies are being put out, a stainless o-ring smashed into a copper gasket is a better solution for high h/p motors.
