Hot Dang!!!!! This hood gets plenty of attention and comments, all positive. I was having second thoughts about the window but loving on the Vents, but everybody loves it. One lady coworker stopped me in the middle of the street to get a look, and then said it was cool. Now I gotta polish and clean up, maybe switch valve cover styles. The vents are a lot more transparent than expected, so you can see the engine from three holes in the hood. You can't creep in a yellow vette with window and vents in the hood.

Some interesting information. I'm always glad to see others who are looking outside the box for lighter parts to put on our overweight antiques. Prior to putting the C5 m/c on my car I looked at several aluminum OEM master cylinders, but kept striking out finding one that would fit. I have a couple similar looking master cylinders in a parts box for future installation onto my street rod, but my experience was that they wouldn't fit the Corvette booster. I've got a spare booster out of a (IIRC) '72, and while the bolt holes line up, the pilot hole in the booster is too small for the m/c to engage into. Do you know if that m/c will fit the Corvette booster? I was wondering if some of the C2500 truck applications use a Hydra boost, in which case the m/c would definitely work in BeeJay's application. This m/c seems to be much heavier (percentage wise) than a C5 part, but still much lighter than the cast iron C3 part.

Yes you can!

The M2903 is 1.750" external and the hdyroboost sleeve is about 1.6". You can't get a 1.750" sleeve into a 1.6" hole.

Beejay,
You're obviously not using a big enough hammer!

Update, M2903 will not fit into hydroboost. I think I need M2904, which is built for the hydroboost. I'll see if NAPA will exchange for me tomorow. The M2903 is 1.750" external and the hdyroboost sleeve is about 1.6". You can't get a 1.750" sleeve into a 1.6" hole.

Wonder if the M2903 will work with stock booster.

I must say that I do not know. My best guess, as a software engineer, with zero experience in fluid dynamics, is that the brakes would be grabbier. I do appreciate you measuring the booster for me, though.

Simple hydraulics. The bigger bore should reduce the pedal travel in cases where the pads/pistons got kicked back during spirited driving, and pedal effort will be slightly higher. (We'll leave it as an exercise for the student to do the bore area math.)
