Re: IML: '65 engine possibilities

["Melissa Swenson" <emswenson@xxxxxxx>]

Hello Scott, I also have a '65 four door-neat cars, huh!?  Anyhow, if I were 
in your situation I would find a core 440 and go that route.  413's and 
440's are dimensionally identical and all of the engine's external 
accessories are 100% interchangable! Now listen, I have nothing against 
413's, in fact if you were going to restore the car, nothing short of a full 
rebuild of the original engine would be acceptable. Since you plan to tow, 
bigger engine = more power. Any year 440 would be o.k. Try to find  a 70's 
vintage one that has hardened valve seats so that it will operate on 
unleaded fuel. The only problem you may face with the 440 is that the early 
one's have too high of a compression ratio for unleaded fuel and towing, and 
the later smog motors have too low of a compression ratio to make good 
power. The solution would be to buy new pistons for the 440 which are 
readily available from many sources. About 9:1 compression is what I would 
shoot for. Right now I don't know of anyone making an off the shelf piston 
for the 413. You will need to re-use your original motor mounts, and more 
than likely, some of the bracketry for your accessories i.e. P/S pump, ALT, 
etc. Oh, your exhaust manifolds too. I've got a good recipe for a strong, 
reliable, mild mannered 440 that I can add later if interested. Electronic 
ignition and a decent 2 1/4" exhaust with free flowing muffers(quality ones 
aren't loud) are a must. At least up-grade to a dual-circuit master cylinder 
and hopefully that trailer has brakes on it too. The stock radiator is a 
little small at 22" but you could add an extra row with the original fan 
shroud without hacking the opening for a wider '66 and up radiator. If 
rebuilt, your original cable shifted trans should be retained to save on 
linkage headaches. Add a trans cooler for long life/reliability. Definately 
hang on to your 413 in case you want to return the car to stock or for some 
future owner. Good luck with your project, we've all got your back!
