Hey Guys, Have picked up a 265 rebuilder. Was a runner but was thinking of freshening it up before I put it back in... Thing is where do I start? I have never rebuilt a motor so wondering what to do first. Im going to leave the bottom end standard so should I just chuck some rings in there? Do I put new bearings in while its apart? I will get the head and cam done.

What prices do I look at to get the block cleaned up?

Any advice would be sweet!

Cheers

Rings and bearings at a minimum if you're gonna pull it apart. Might as well do the frost plugs too.

Ok cheers mate, Whats worth doing on the head. Cheers

Machine the piss out of it for max compression

Nah, but a quick skim to give it a nice face for the new headgasket to bed to wouldnt hurt.

Choice!!

Find an engine shop with a good rep. Get your block tanked, and honed. If you don't have a micrometer, get the shop to measure your crankshaft. If need be have the journals reground. Get you rotating assembly balanced. You''ll want to get a new balancer. The guys at moparmarket.com forums rate the ross ones.
Get the shop to fit new cam bearings too.
I'd consider having the block deck machined to zero too. Buy some new lifters, and either get a cam place to regrind your cam, or buy a ready to use cam. Personally, I'd lend more toward reusing the cam core you have now, as it'll be matched to the gear on your oil pump.
For cam choice, talk to whoever is going to grind it, and get something to suit your needs. There zero point in getting an E49 grind cam, if you plan on using the standard two barrel carter carb.
If your motor doesn't have the afterthought timing cover bolt can endfloat elimitaor, then it'd be best to add it.
Dont forget to get a good quality timing chain and gear set too.
With the head, get the guides replaced, and the seats recut. Given the age of our beloved hemi 6 motors, don't be too suprised if the head needs to have new seat inserts fitting to it.
Much of the above work can run into quite some $$$.
So you might just want to get a quick hone, and slam in some new bearings.
BUt if you want a motor that will go hard, and you can beat on when the mood takes, you'd be much better off to spend the extra $$$ up front.
YOu're also going to need new valve springs to match the cam. (Depending on how radical a grind you decide on)

any engine responds to the 4 (was 3) C's

crank .... to be safe
cam
compression
carb

unsure how mental you are going, but the locals with the 265 (or 245) in streety or stockcars make sure crank is good and do shells,bump compression to legal 10:1, fit max cam for class (E49 spec is limit, i believe) then use the XF Coon Weber as it is matched to the restrictor sizing. to make gas escape, the twin port exhaust is a good option if flows are not readily available.

unsure about balancing, the Hemi likes to rev, but unless mental, i don't deem balancing as essential.

Ok thanks guys. Budget is limited and not going crazy on power. Just want a little more than what my 245 is doing. Will see what budget allows.

carter carbs are more than up to the task of keeping a camd hemi revving..

but i would chuck on a 500 holey 2 barrel just for shits and giggles,and a speedway cam grind.
theres not a huge gain from porting the head on these unless you plan to run triple carbs and extractors, maybe just a clean up would do.

make sure you get your oil pump cover modified to stop end float in the pump assembly,some places sell alloy covers with the anti float bolt allready fitted.

electronic ignition would help this fire a lot too...something i never got a chance to use in the stockcar.
these things are torque monsters not rev heads, so try not to treat it like one and shell be all good..

The carter carbs fitted to Vals were lemons.
They were produced under license in Australia by Email ltd. I've read that they had numourous quality issues. From my own personal exprience, some hemis are really good on gas, and other were gas hogs. Since you're going to want to fit headers, try to get an aftermarket Aluminium inlet if you can source one at a good price. (Try ebay au)
Untill you pull down your donk, you wont know how good what you've got to play with is. Shit gets expensive quick when it's out of spec. And because it's all so old, it often is. Strip it, and have a good measure up before you form a plan. (ie, know how much the basics are going to cost you)

[lowrota]

Good idea. Will see whats the go. I have a holley 350 on my 245 that I can use.
