There is a port on the side of the block you can use. goes into the water jacket.

Maybe a hydraulic shop can help you with the hoses. Must be nice to have all that space to work with. :) It even looks like all the header pipes are on the same side of the column.

Of course this is a 64 dart, but there is a mini starter down in there somewhere. Lord help be if I ever need to replace it. :)

THat is why I mentioned you may need to get a Ujoint for the steering as the "rag" joint box is too big. I got the one with rubber in it to take out some of the whine in the steering wheel.

Power steering and a 4 speed is going to be fun, had to go with a flaming river ujoint to get that to work, and the zbar still hits the header. Is this an early A ?

Are you sure your rings are broken in ? Also you aren't running the 273 crank in a 340 are you ? 273 anything on a 340 is no bueno.

If you are using a throttle body you probably dont want a dual plane.

you have a bigger Radiator than what is in a 64 dont you ?

My 340 in my 64 dart overheats also and nothing but an electric fan helped. By the way lowering the temp of your thermostat doesn't increase the cooling ability of your system. if it is overheating with an 180 then it will overheat with a 160.

You can get hardened bolts from ACE that will work.

Well I know one thing if you have a set of bolts for an iron bell, don't try to use them on an aluminum bell, they aint long enough and will back out on their own. learnt that the hard way.

[FOR SALE] - 340 Rebuilt Short Block

If your engine was still together I would suggest trying it without the spacer and with more spacers to see if it made any difference in the running of the engine. PS. I am also interested because I am adding a fitech to my 340, and I am hoping to avoid such issues. I have an airgap, a...

I only brought it up, because, it potentially could skew the AFR at idle speeds which could in an engine that had varying compression ratio between cylinders, cause the engine to misfire and shake. Just spitballing here, not looking for a fight.

Well a Carb only supplies fuel to the barrel that is being used, but a tbi blows fuel in all barrels whether they are being used or not, so with a spacer you will still have too much air in half of the carb and not enough in the other. I would think this would cause some kind of imbalance.

On another subject, is it wise to run a dual plane intake on a throttle body injected motor? I dont think the TBI knows which side to spray in, so it sprays fuel even on the sides not sucking air. This could cause poorer performance on the low end. Just a theory on mine.

Check distributor for cracks.

I wonder what would happen if you ran the motor without the harmonic balancer.

That looks awesome, but I would check the hood clearance, I know it was a problem in my 64.

I have a 1965 rebuilt 273 with around 3k miles on it. I would sell you for $1k plus shipping from Florida. It came with the car I purchase and a swapped in a 340 that I had built. I have a video of it running when pulled. depending on when your car was built this would keep you numbers...

Are the bores heat treated on blocks ?

So install a stock 360, and tell people it is a stroked 273, I am not sure you will be able to tell the difference.

I love it when people take an engine made for revs and turn it into one that isn't.

wow that looks tight, you had better have good motor mounts or a torque strap of some kind.

Nitrous is cheap, 340's aren't.

I wonder if the lowend problem is because of turbulence messing up the AFR, in the low end, and if running an FITECH would fix this.

I will never let the carbon build up that much, I just use it for the extra zinc in my 340. works well in my lawn mowers also.

I am using shell T6 15w40 https://www.walmart.com/ip/Rotella-T6-15w40-Ck4-2-5-Gallon/847530443?athcpid=847530443&athpgid=athenaItemPage&athcgid=null&athznid=PWVUB&athieid=v0&athstid=CS020&athguid=688a6f2e-007-176d082ffea4e7&athancid=null&athena=true

I didn't say it wouldn't work I just said it doesn't work well, oir as well as it could. There was an engine masters video that pointed this problem out, but they didn't say why there was a problem.

That is why they cut the center section between the barrels out of a dual plane manifold for TBI.
