A better common block? Russ Jerome?

[packrat_turbo]

Has anyone compared these blocks, as far as comparing weights?
If castings in Mexico are so much better, why are so many people illegally crossing the border into the U.S.? It boggles the mind!

Que???

[78Dodgekid]

I have an 89 shadow with the 2.5 ,built date 10-88 but the "C" is backwards.

Any ideas?

[1985ShlbyChrger]

I got a motor from an 89 Lebaron GTC TII car that has the C on it. Build date is also 10/88 I believe.

nimby. Not in my backyard. Aluminum foundries take a LOT of electric and I assume emit gasses. Canada built a foundry in southern Mo. because of a special cut rate on electric and tax incentives. Mopar had to build in Mexico because US companies don't get the incentives foreign companies do. It is just a more modern plant in Mexico.
If we gave the same breaks to US companies, they wouldn't move overseas so quickly.
Why do the Mixicans still cross the border? They get paid 10% of what Chrysler pays in the US.

[bluneon]

stock production turbo blocks came crossdrilled. but for efficiancy's sake chrylser later on just used the same crossdrilled block after around 91 model year. my 94 2.5 TBI has crossdrills in the block AND head.

not all stock turbo blocks were cross drilled,i thought the 88 t2s were the first to get the crossdrilled head or block

[turbodudehere]

The block that I have all machined up has the date code 12 E 94 with out a C, hope this will hold up to some serious power ?!?

[shelbyplaya]

heres a cuple pics of my blocks.. i've noticed no differnts between then 2 other then this.. i've had a few blocks with no letter cast into them, as well as blocks with a 'C' and a cuple blocks with a 'B' cast into them.. take a look and tell me what you guys think...

Just picked up a C block today in a 12/88 Lebaron GTS (Hbody) Casting date is 1/8/88.

[beyond_audio]

so has anyone actually had the metal tested to see if it is stronger on the "C" blocks?

[looneytuner]

I think it has more to do with the bore location of cylinders. I saw a pic where the head gasket doesn't mate very well to the bores on some blocks. The bores with the old technology are not as precise as the new casting method. This would also affect thin spots in cylinders. Somebody had a post on the new casting method. It said the sand molds are computer made for each pour. Less chance for a bad casting. This should give better uniformity and strength with the same weight or even less.
