hey guys, im new here. i do not have a grand national, or a turboed 3.8 liter. but i do have a mazda b series. and i am looking for some help. i just got this truck and it has a 3.8 l buick in it. i looked around and found a couple things. like mi dizzy is like the even fire as shown here, http://members.toast.net/rbuchholz/heiexp.html as opposed to the odd fires.
and i looked here.... http://www.earlycj5.com/technical/engines/dauntless-225-v6buick-231-oddfire/buick-v6-casting-numbers-internal-specs-for-most-years-and-notes/ and found that.
and then, shockingly i ran upon this http:

QUOTE "The way to find out exactly what kind of engine you have is to look up the serial number cast on the engine block near where the bell housing bolts to the engine on the top, you might be able to see it looking down the firewall of the engine compartment to the top rear of the engine. The valve covers style make the engine look like a 1976 or later Buick V6. The Buick V6 changed from odd-fire to even-fire in mid-year 1977. You might have the very latest odd-fire that had the external appearance of an even-fire engine. The 1976-1977 odd-fires are the strongest Buick V6s ever made, stronger connecting rods, single piece cams, large wrist pins.
When ever in the junk yard and you find a Buick V6 with an odd-fire HEI check out that engine it might be the last and greatest odd-fire of them all If it has freeze plugs in the heads it might be a super duper 1976 odd-fire. These odd-fires have a very strong bottom end because the odd-fire crank combined with stronger Oldsmobile V8 style connecting rods. The oil stick even enters the block like an even-fire everything looks even fire until you see the casting on the drivers side under casting says “76″ on the block, you must pull the oil pan, see the odd-fire crank shaft. This was the transition series of engines. QUOTE
so i checked the heads, and there is freeze plugs in the back of them, and maybe in the front of them, idk stuff is in the way. i couldnt find the "76" stamp they were refering to though..... could this be that rarer motor?
