Default lt1 swap?

i have a 80 vette im looking at doing a LT1 swap and i tried the archives search but nothing came up,im agoing to install a 700r trans 1st and then in jan or feb install the lt1,im planning on doing an aftermarket harness to make the swap easy and i looks like if i find an lt1 out of a vette it should drop in a/c compressor and all with no problems, does any one have any info links or pics of the swap,thanks for any help or info

raw, both engines will be a good choice for a swap, LSx or LT. Cost between the two will be the biggest issues as the actual swap is about the same really. Parts availability for both is excellent. Wiring between the two is different but I wouldn't say one was harder than the other. The LSx does hold more power potential for less, but if you're not building for big power than that factor no longer matters.

In general, you already know about the wiring issues. The transmission you're looking at requires a new DS. A 2004R does not and is an OD auto. You need to add an electric fuel pump. Edelbrock offers a nice one that's actually made by Walbro. I have used this one before on a 73 vette we put EFI on. You'll need fuel line fittings for either engine. We have Russel fittings available that slide onto the smooth fuel rail barbs and have 6 AN fittings to connect up to the fuel line. Some other minor issues are there as well but nothing major.

The choice is yours. Either will be a good choice.

the 200 is a easier swap,but the 700 has a lower first gear 3.06 which helps accelerate off the line better and the overdrive is different between the two.
FIRST GEAR SECOND GEAR THIRD GEAR FOURTH GEAR 700r4
3.06:1 1.63:1 1:1 0.70:1

200
2.74 1.57 1.00 .67:1

DS is drive shaft. Sorry, I need to get better about using slang. The 200 is a lighter transmission too. Which one is stronger is a big debate.
