    Manual Brakes

    in Modifiers

    Posted

    I did this years ago.  Long story short, I bought some aftermarket 2 piston calipers (Power Stop?) and they stopped worse than the stock single pistons.  I then changed over to manual brakes with a master cylinder and rod from Master Power Brakes (I think), and used the different mounting point on the brake pedal.  Still didn't stop well, so I went back to stock all around.

     

    BUT, I never tried the manual setup with stock single piston and standard type pads.  It may work better than my manual setup with the dual piston and performance pads.

     

    I also tried a vacuum pump and hated it - too noisy and results weren't that great.

     

    I wish I had a better answer for ya.  Try the Chevelles.com, betcha somebody will chime in.

    I just got the news from this post......so sad.

     

    I spoke with Crazy Davey a few times when I was building my 502 and he was just the nicest and most helpful person you could ever want to meet.  Heck, he even sent me a 502 flywheel (for free) when I couldn't find one locally.

     

    RIP Davey

    What did you do to your Monte Carlo today?

    Nice day so time for a bath.  Also raised front end about 2" and while I liked the stance, Headers to close to the ground for my comfort.  Also investigated Factory Tach accuracy suspicion by measuring it against a RPM Meter.  I knew it was off but had a suspicion at different higher RPM's, the difference between the Meter and Tach would grow further apart (with the Tach reading the higher RPM's).  I was right, at 4000 Tach RPM, Meter read 3300 RPM.  At 1100 RPM, Meter read 1050.  I also did some inbetweens so I can more accurately measure actual RPMs.  Next will be trying to read actual engine temperature using the factory gauge.  I'll have to paste new numbers over the gauges plastic faces to remember what each is really doing.  :k  Anyway, here is the new stance look on a freshly washed car.  The third pic is what it was prior.

    That's a huge rpm difference!!  Seriously, how do you fix that?  I had a similar issue with my VDO tach and it really messed me up when I went to the track.  My shift light wasn't matching the tach and turns out my tach was reading too high......

    SS 454 rear gears

    I put a post up a long time ago regarding the 2.56 and 3..31 gears in the SS cars.  I have yet to find a 70 SS that had anything other than a 2.56......same goes for the 3.31 in 71.  I'm not saying they didn't exist, but  I haven't seen otherwise.  Oddly, the Canadian version of the sales brochure lists 3.31 as the only gear for the 70 SS454, yet all I've seen is 2.56 for 70.,

     

    Anyway, I agree with the others that 3.31 is a great all around gear.  With 3.31s, I have found that you can really tweak your highway cruising rpm with tire size.  With a shorter tire, I find myself in the slow lane doing 3000 rpms at about 65, but now I'm running the tall 28" tires (275/60/15), and I cruise at under 3k at 70....in the middle lane!

     

    If you are building a low to mid range 454, I think the 3.08 would be the best all around gear for both city and highway....maybe with mild converter.

     

    Dennis - those mph/rpm calculations include torque converter loss?  With my mild converter, I take my foot off the gas on the highway and the rpms immediately drop like 400 or 500 rpms.

    My first car....

    I don't have any pictures (wish I did) but my first car was a 1971 Ford Maverick Grabber.  I was 14 and couldn't yet drive but I bought the car, which was pretty much junk, with money I had saved from mowing grass and delivering papers.  I had hoped my dad and I could fix it up for when I could drive.  Unfortunately, the car was to far gone and it turns out my father was not capable of performing miracles like I had thought :grin:.

     

    So the first car I had that I could actually drive was a 1970 Monte Carlo.  It was silver with a black vinyl top, had the bucket seats with the floor shifter and the big block (402).  I just recently started a search to find a restored or restorable version of that car and have found one that I hope to have in my garage in the next few days at which point I will have pictures :grin:  :grin:    

     

     

    Good luck with the purchase!  Silver with black top was the car that I saw while riding my bike as a kid, and I thought it was one of the coolest cars ever with that roof line and fender bulges......

    Great find! I own a 72 original "w" VIN 454 car, but not a custom. I thought mine was rare, but this is great!

     

    Same here!  Midnight Bronze originially......

     

    I want to see pix.  Great find!
