Building my 273

my66fish said
I have just pulled the drive train from my 1966 Barracuda and I'm trying to figure what I should have done to the engine for this build. This 273 is a two barrel / 180hp engine, and I'm looking to give this engine a mild build. Nothing over the top because I want to keep it towards the stock side but give it alittle get up and go at the same time. I have gotten a edlebrock 600/1604 carb. I have a factory steel four barrel intake, Mopar performance electronic igntion.
I'm planning on having the heads redone, a mild cam, and all new rings and bearing along with a new timing chain and gears.
Am I missing anything?
Any suggestions with regards to the cam size or head work or block work?
Some people have said a 600 edelbrock is to large for this engine.

Once you get into it, you might end up needing to bore and replace pistons. I thought mine was just tired on the bottom end, but had a fairly thick ridge at the top and ended up haveing to bore it out .030 to get it smooth. If you have to bore it, you may just want to upgrade the pistons to the Commando Pistons (From Egge) as well as balance the rotating assembly. Then you'll watt a little hotter cam... etc. etc.

One thing for sure, when 'refreshing' while its out, put a high volume, standard pressure oil pump in, New freeze Plugs, etc.

Just my .02.

G'day. I too am rebuilding a 273. I am in Australia. If you can help me in locating a reputable USA supplier I would appreciate. See my query to the forum Administrator. Cheers, Buddy :)

Hello,

I was wondering if you can assist me with reputable engine sellers. I need an engine from the USA. I am based in Melbourne Australia, and with the high dollar can afford to buy an export motor.

Preferably a fully rebuilt 273 ci LA engine or if these are rare, as they are in Australia, advise on a 360/5.9L engine that would suit the same mounts as the 273 A Frame Chrysle Valiant VE model. The car has the originl engine but I need a replacement. If someone is willing to swap a rebuilt 360 I will trade them the tired but daily driving 273. Suit Dart etc.

Please pass on my details. Your help would be appreciated.

Buddy, If you have machinist down under that can prep the block, you could order most of the parts from the states and have them shipped down for you could assemble your original 273 and put her back noto her car.

If you're truly looking to have a US machinist build a 273 and ship it on a boat down to you, I can recommend one to you from Las Vegas area, but you'd probably want someone from the coast who has a dock he can go drop it at. This machinist did all the block prep work for my rebuild. Probably the best machinist I've found. He builds quite a few race engines for some of the pro's at Las Vegas Motor Speedway. I'd bet with a base engine block, he could assemble something together for you and not break the bank too bad.

I dont know if Mopar Performance will ship an engine that far, but they do have crate engines that they build at the factory that will probably bolt right in.

Just a few thoughts
