What do I have? (289 teardown)
PSA: Please bear with me - this is my first time ever looking at the internals of an engine, so I'm a total newbie when it comes to this stuff. Trying to learn and make a plan of attack here.
I pulled the 289 out of my '65 this weekend as I continue the overall teardown. Seeing as I was 14 when the motor was built, I didn't really get to be very involved in part selection. Couple that with the fact that my dad isn't the best at documentation, and I'm left trying to piece together what exactly is in my motor and what I should do to/with it. The engine was rebuilt in late 2001 and probably has less than 10,000 miles on it since then. My original plan was to fully rebuild again and do a roller conversion (at the recommendation of my engine builder), but as I got to thinking I was wondering if it made sense to try and limit doing a full rebuild and focus on heads, intake, and carb. The motor has always had a little tick, but I know it had an exhaust leak (headers) and I was told it had solid lifters, which made more noise (I've not been able to verify that and I doubt it based on cam info I've found). Here's what I've been able to decipher, based on receipts and what I've disassembled so far:
- C5AE-6015E 289 block - bored 0.040" over
- Turned crank/resized rods (no more information), ARP rod bolts
- Speed-Pro L2482F40 0.040" overbore flat-top forged pistons
- Clevite 229-1734 camshaft (looks like duration @ 0.050" is 204/214 and lift .448"/.472") with new (unknown) lifters
- Clevite 215-4051 push rods
- Clevite 211-1915 and 211-1932 exhaust and intake valves (stock replacements, it looks like)
- Comp Cams 144216 Magnum 1.6 roller rockers
- Edelbrock Performer intake (definitely being replaced)
Tonight I took the valve covers and intake off to look around, and everything seemed to be really clean and basically brand new to my untrained eye, outside of some oil in the area around the lifters and under the intake. Next I plan on flipping the motor over and pulling the pan to check out the crank and rods/bearings/caps, although I admittedly have little to no idea what I'm looking for. I've added a couple pics with the intake removed and I'd be curious if anyone notices anything alarming based on those (for instance, is there supposed to be any oil in the area under the intake? I don't know what's normal).
I've downloaded How to Rebuild Your Small Block Ford and I plan to read/learn, but what I'm wondering is where people would go from here. Do I stick with my original plan to have it all torn down again and rebuilt, or based on the specs and pictures should I just clean it up, verify everything is within spec, and just focus on a new intake and improving the heads? Any advice anyone has on what to look at next in the motor? Is the fact that the crank has been turned a major issue? If there are any particular pictures anyone wants to see, I'd be happy to get them.
I was running Tri-Y headers and an Edelbrock 600 carb, and plan to switch to Hipo manifolds and a 4100 (have access to both a 1.08 and 1.12 - leaning 1.08 for throttle response). This will be mated to a Z-spec T5 and used primarily for backroad/highway cruising - no track time. I would prefer more low end than top end power, as I generally stay below 4,000 RPM. Thanks for taking a look and for any thoughts or input anyone has as I venture into my first real engine rebuild experience.
