If it's a third gen, I've read just to pull off the nose cone, and lift the engine out, take the trans if you want. Hawks Third Gen (online) or summit racing will have everything you need or want for a rebuild, depending on your budget.

Well so far ive done 3 thirdgen engine swaps so let me try to pass some knowladge across the pond to ya.....


Its easier to pull the motor/trans as a unit. Even if you separate it and pull just the motor, youre going to have a hell of a time trying to bolt a new motor on a tranny thats still in the car. Trust me, save yourself the headache and bloody knuckles and just pull it as a unit.

Also, get an engine hoist with a long boom, or youll have to pull the motor from the side of the engine bay. (the nose on our cars is a lot longer than it looks) Not to say that you cant pull the motor from the side of the car, ive done it. But once again, its a royal pain in the ****

Oh and once that 305 comes out, you may as well use it as a boat anchor, thats about all its good for. Trust me, build a 350 youll be much happier.

Let me know if you have any more questions

You can get a rebuild kit through Summit Racing or Jegs. But before rebuilding anything I would run a compression/leakdown test on the motor while still startable, then take the motor out and disassemble it and see what is broken. No sense buying a complete rebuild kit if only the headgasket is bad (just an example). When I've removed engines it I've always pulled just the engine, no sense removing the trans if you aren't going to work on it. But thats just my opinion.

i am going to second (third actualy) what "StreetRoc85 350" said. if you are leaking oil from the head gasket, and the block itself is fine why rebuild it? just replace your headgasket, put it back together and flush your oil and coolant a few times. good to go.

and also, i know it may be difficult to find a good block over on that side of the atlantic, but if you have to rebuild, and you can get ahold of a 350 block you will not regret it. if in proper tune it will only get slightly less petrol effeciancy then the 305. and you will feel the difference when you hit the accelerator.

so, over here we say Miles Per Gallon (MPG) regarding fuel/gasoline consumption, do you guys say Kilimeters per Liter or somthing? do the english have an acronym for that? just wondering...

well i finally got the bitch out thanx for the pointer StreetRoc85 350 found it alot easier than i thought just removing the engine and tranny as one unit, took longer though as every five sec kids coming up is that the car of knight rider and after 50 times sayin yes i thought i was turnin mad!! Anyway back to the engine the block seems fine after a blast clean came out nice and the oil was coming from the passanger side head gonna have a closer look tomorrow, when removin the valve covers the idiot that put them on put most of the gule on the tappets and the crap lyin around was a joke looks like hair or somthin this car has been abused why.. why bother why do people do this only peneys of gaskets ect.


Still thinkin of puttin a 350 in, will make my mind up tomorrow if its really bad, and Xophertony we use the MPG think the only things we do different is the temp we do it in oC and not sure but we do Miles and do you do Kilomiters? and drive on the other side of the road which when drivin an American car anit that easy even on roundabouts need a passanger to help out, one last thing what should the MPG ona car like this should be i think i was gettin about 15MPG and with petrol here being 97.9p ($1.78) not cheap to run, aways what the price their for petrol (gas)??

Glad i could help. I know what you mean about driving an "american" car on the other side of the road. Believe it or not besides american muscle i also have a bit of an english fetish, that being MGs. My first car in high school was a 1957 MGA roadster (still have it). My dad has a 1948 MG-TC w/ right hand drive and it is a pain in the **** to drive around here on the wrong side of the car, esp when changing lanes....


Oh and btw, we use miles over here as well, its the canadians who are stuck on kilos..... Gas is about $2.75 a gallon over here and my 65mpg gixxer takes about $8 worth of gas to scoot me around for a week.

Also why does the engine coolent turn a rusty colour in the block??

Yes pull the tranny with the motor and If you want to rebuild a 305 so be it, dont let people talk you out of it. There are some people who have 305s that have awesome et's. I personally got rid of a 305 for a 350 but thats my preference. Keep in mind its cheaper to rebuild a 350 than a 305. and a 350 will always produce more Hp than a 305 with same components... but there is nothing wrong with a 305. Very respectable..

We are a screwed up people here. Speed limits in km/hr, distance in km/hr. If I talk mileage to anyone, I convert to MPG. Usually american gallons, and not imperial gallons however. Outside temperature is in celsius, indoor (on my thermostat in the house) is fahrenheit. Flyers in the paper advertise meat at $/lb, in the store the signs show $/kg. Electronics are in metric, mechanical industry in imperial. I have to mill out an enclosure for a PCB, the electrical engineers speak metric, and I convert to inches so I can turn a dial on a milling machine. I'm seriously getting sick of being in purgatory here. DECIDE FOLKS!
/rant.

Gas is a solid $1/litre. In USA that would be $3.73/gallon, across the pond...?


anywho,

white chalk like substance on the piston heads
That's usually running LEAN. Rich would be black.

also found more crap like hair and plastic bits and even some really think oil around the sump and the heads and a thick layer off somthing in the exhaust ports on the heads can be picked out by screw driver but no idea what it is
ugh! gross! Grab some engine degreaser and go to town! The crap on the exhaust ports, I could only guess would be old gasket material...? oh wait, IN the ports... ?


rusty coolant is pretty normal, based on what you've said so far. Sounds like the motor wasn't taken care of, and didn't have the fluids changed very often.

Check the bores, if they're *ok*, you could just hone it out, and put new rings and bearings and gaskets in the motor. Otherwise, see if you can source a 350 there. Shipping a 350 block across the drink would make a 350 swap MUCH MORE expensive then it is over here. I'd recommend building up the 305 in that case.
