Hey everyone, I just posted this on the VITCI site as well but I wanted to copy it to here as well. I hope this category is okay, I put it in General discussion because the engine parts vary by a few years and I figure it can use every ones expertise. Basically I need a new camshaft and the valve lifters between the two cars are different heights, but I'd like to start by giving you a bit of background. I apologize ahead of time for the long post but I'd just like to provide you with as much information as possible about the engines.
I own a '62 Hardtop (I'll always refer to this as MY car), and last year I bought a parts car, '62 Hardtop as well. I was told it was running, but personally never saw it run, I only really cared about a few of the parts on it anyways so it never phased me.
Just recently my dad and I pulled out the engine from my car to go through it and rebuild it. From what we can see it looks like someone had gone through it in the recent past already. It ran great when I bought it so I know everything works. We also pulled the engine from the parts car so I can sell it and swap parts if needed/compare.
Well this is where we started noticing a lot of differences between the two and we're not sure what is right. Although my engine worked, we're wondering why certain things are different, and what I should be using in my engine.
I'll list the specs and numbers below for both cars.
*indicates the most significant differences
MY car:
VIN: 2Y83Z115564
Date: 04L
*Engine Block #: C1AE-6015C
Heads #: C1AE-6090-A
*Camshaft: Spring thrust type
Camshaft lobe width: 1.530"
Camshaft lobe width: 1.725-1.755" (measured a couple)
*Valve Springs: Dual Springs
Valve Spring Height: 2.09"
Valve Diameter: Exhaust - 1.56"
Intake - 2.25"
*Hydraulic Valve Lifters Height: 1.85"
Crankshaft #: C1AE-A
Pushrods: Same length as parts car
Valves: Same height as parts car
Rockerarm Assembly #: B9AE (mounting holes are round, otherwise looks exactly the same as parts car)
PARTS car:
VIN: 2Y83Z50523
Date: 14C
*Engine Block #: C6ME-A
Heads #: C1AE-A
*Camshaft: Thrust plate type
Camshaft lobe width: 1.495"
Camshaft lobe width: 1.680-1.705" (measured a couple)
*Valve Springs: Single Spring
Valve Spring Height: 2.25"
Valve Diameter: Exhaust - 1.56"
Intake - 2.35"
*Hydraulic Valve Lifters Height: 2.00"
Crankshaft #: Cannot find number
Pushrods: Same length as my car
Valves: Same height as my car
Rockerarm Assembly #: C2AE (mounting holes are slightly squared, otherwise looks exactly the same as parts car)
1. WHY are the Hydraulic Valve Lifters in each car so different when everything else is so close to being the same? Which car has the right ones? Considering my car was running, I would guess mine are right but we are really perplexed as to how the parts car engine (supposedly) ran with such different specs. I know from the casting numbers that some are '61 and the parts car are '66 (?).
2. How do I go about finding a new camshaft for my car? I've been told I should go with the thrust plate type, but otherwise is there are part # or type that's out there that will work with what I have?
I'd just like to know what is right and what is wrong so that I can find the right camshaft and maintain/fix the engine with the proper knowledge in the future. If you require any more information please let me know and I'll try my best to provide it.
Thank you for your patience!
