Morning,
I have a '79 C10 350/Auto with a noise speedometer cable. My truck has the two-piece (upper and lower) setup.
I've removed them to measure and get a new set, but I can't find anything that matches. The lower cable is 23", and the upper cable is 44".
On the upper cable, I can find 41". Short but close that maybe I'm not measuring it the way the factor does. On the lower cable I can't find anything close to 23". Also, I'm not sure if they have the right ends. Some pictures show a male end like I have, some show female, and some show something completely different.
Why is the cable two pieces anyway? Seems like it just complicates things.
Am I missing something obvious here?
I did remove the drive on the transmission. The gear was in perfect shape, and the square drive looked good, too.

Sorry I missed the part about pulling the starter. You have to pull the starter. I was thinking without replacing the starter. Not much to pulling the starter though! You cannot get to the screws to remove the solenoid with it installed.
You can buy a Starter Solenoid for about $20.00 if you just want to replace it. It is fast and easy to replace. Take out 2-3 screws that hold it on and disconnect the wire on the back. it will come right off.

Yes, I did many years ago. Have not done it lately because anymore I just replace the starter. Some starters at local parts shops will give a lifetime warranty.

Greetings, Can the starter solenoid be replaced without pulling the starter? Looks possible at a glance... Thanks, Aren

Don't trust them, avoid them! Besides, don't do business with anyplace in NY.

Anybody ever buy from automobiles and accessories? Can’t tell if they are legit or it’s a scam! Seems kinda fishy. Won’t take credit card or pay-pal. 501A W 45th St, New York, NY 10036, United States

I checked out the 1995 Cprice 5.7L engine and the pushrods run just over 7.8 in length. I used a couple of methods now (last time today) to check for the correct pushrod lengths and both methods came up to a 7.200 pushrod length.
The last method I used to check the pushrod length was very easy and effective. I checked for the rocker geometry, which gives you the length of the pushrod. Seemed to be very accurate.
Rocker Geometry: 1) The Gross Valve Lift of Cam: .792 / 2 = .396 2) Thread Pitch on 3/8” studs = 24 TPI (.042” per turn) 3) Make 90 Degree Mark on rocker arm (Center bearing to Center roller) 4) Put a mark on top of adjuster nut so the number of turns can be counted 5) Put Rocker on the stud and measure with an Allen wrench from valve to stud the 90 degree line. 6) Figure to determine turns on adjuster nut: .396 /.042 = 9.43 (turns needed) 7) Put tape on top of adjuster nut and mark it to determine the number of turns.
Figures: Intake Lift .495 Exhaust Lift .502 Rockers 1.6:1 (Full Roller - Scorpion Rockers) .495 x 1.6 = .792 (Gross Lift) .792 / 2 = .396 (Half of gross valve lift) .396 / .042 = 9.43 (Turns needed on adjuster nut) Afterwards: Insert and adjust pushrod checker, then removed rocker and pushrod checker. Measure pushrod checker.
Equation used to find Gross Valve Lift: Intake Lobe Lift x Rocker Arm Ratio = Inches Gross Lift
I went ahead and ordered and the information on the pushrods from Summit Racing is below: HDR Thickwall Chromoly Pushrods SUM-14957200 Compatible with Guideplates: Yes Pushrod Tube Diameter: 5/16 in. Pushrod Material: Chromoly Top Tip Style: Ball Bottom Tip Style: Ball Intake Overall Length (in.): 7.200 in. Exhaust Overall Length (in.): 7.200 in. One-Piece Pushrod: Yes Oiling: Yes Tapered: No Tip Attachment: Formed Top Tip Diameter: 5/16 in. Bottom Tip Diameter: 5/16 in. Wall Thickness (in.): 0.105 in. Heat-Treated: Yes Quantity: Sold as a set of 16. Notes: Commonly used with SBC O.E. hydraulic roller cams, .105 wall 210 degree ball ends. Summit Racing™ HDR Thickwall Chromoly Pushrods Summit Racing™ HDR premium thick-wall pushrods are a great upgrade for your engine. Factory pushrods (and even .080 wall aftermarket versions) act like a pogo stick in a running engine. Not only is static spring pressure working against them, it's also the valvetrain inertial mass increasing with RPM. This reduces power and valvetrain life. While a .080 thin-wall pushrod may not break, it doesn't mean it's the best option.
Enter the HDR's. Summit™ used FEA (Finite Element Analysis) in the initial testing. We didn't just compare them to thin-wall welded-ball factory pushrods, but with aftermarket models, as well. The results speak for themselves!
* The Summit™ HDR 5/16 x .105 wall pushrods have 20 percent less stress and 25 percent less deflection than a typical 5/16 x .080 chromoly pushrod * The Summit™ HDR Pro LS 11/32 x .120 wall have 25 percent less stress and 28 percent less deflection than a typical 5/16 x .080 wall chromoly pushrod

Don't over think it. You need the pushrods I mentioned above.

I have seen a few different methods for measuring push rod lengths. I will do my measurements again tomorrow to double check my pushrod length and the proper geometry of my rockers arms/lifters.
