Manual or Hydroboost?

[68Formula]

I just put hydroboost on my S10 that runs 10's on motor and 9's on spray and love it. I love having power steering and power brakes that will stop on a dime. I got my hydroboost unit off a 93 Astro van for $20 at a local salvage yard. Bought my master cylinder for $30 at NAPA and ordered my lines and fittings from Jegs. Got about $250 tops in it. Line and fittings was the most expensive part.

Do you have part numbers? Did it require bracket fabrication?

Thanks.

I didn't have to do much fabrication at all on the S10 because it used the same brake pedal rod. What I plan to do on my Camaro is cut the rod on the hydroboost unit weld a 2" or 3" sleave on the rod and then cut a Camaro rod and insert it on the other side and weld it. I used a round track late model power steering pump with remote canister with head mounted bracket from Speedway Motors. I didn't have room for a power steering unit down below to use a factory power steering unit. I think the only other modification would be to make the hole in the firewall a little bigger for the hydroboost to stick thru and it bolts on with four bolts. MAKE SURE YOU GET A HYDROBOOST UNIT FROM A 1990 - 1993 ASTRO VAN! It has a flat bracket and installs flat on the firewall. Most units will have a tilted bracket. You can modify the bracket but it takes forever. I used a late model truck rebuilt mastercylinder part #390257 from NAPA that cost $30. I would recommend going to a parts place like NAPA or some place they can look up part numbers.Below is a list of part numbers for early model mastercylinders that will work as well.

36306 - GM Camaro 1.125 bore
39052 - GM C6 Corvette 1.125 bore
39018 - GM C3 Corvette 1.125 bore - uses deep push rod
36367 - GM C3 Corvette 1.000 bore - uses deep push rod

Below is a diagram of how it all installs. I hope this helps everyone.
