I am going to be putting my Lt-1 in this month. I was woundering if anyone had pictures of what has to be done to the frame/engine mount to keep the ac? Thanks, Kory.

LT1 or LT-1, there is a differnce. LT-1 being the 1970's version and LT1 being the post L98 small block.

91 RS W/carbed 350, Vortec heads, performer rpm, Comp cams Xtreme energy 226/230 duration and .477/.480 lift. BFG Drag radials. 3.42 posi,Corvette servoed 700r4, ****ty stock converter.

Just like the 2000 LS6 and the early 70s LS-6 right? Who cares? if somebody says im putting a LT-1 in my car we know then mean post L98 because noone in thier right mind would pick a 70s LT-1 over a 90s LT1.
sorry to be an A-hole, but why get technical?

Plans for an LT-1 or LT-4,
also plans for dual flowmaster exaust.

Got a corvette when i was 16, paid for it myself, screwed the engine up (idiot light didnt work, and i trusted the guy when he said he just changed the oil), and it turned into a project car.
now my TA is my daily driver. not a bad one, but it needs to be faster.

My thoughts exactly.. I would imagine that if he was putting the early 70s LT1 in, he would just say that he's putting a 350 in.

www.hpsalvage.com/3rdGen.htm has an article on this that should be helpful.

Let me say this as nicely as possible and I'm not trying to start a flame war. If you didn't have to meet emissions, the 1970 LT-1 would be a great engine in anyones thirdgen f-body. 370 GROSS horsepower (Corvette or 350 horse in Z-28 with the main difference being exhaust manifolds and Chevy's reluctance to have lesser cars rated near the 'Vette) at 6000 rpm (5600 in Z-28), 380 lb. ft torque @ 4000 rpm (380 @3600 Z-28). 11:1 compression, High-rise aluminum intake, Holley carb, 2.02 intake, 1.60 exhaust heads, solid lifter cam (.450 something lift), steel crank, 4 bolt mains, big balancer, etc. GRANTED, these are gross rated power figures, but the 1972 LT-1 using today's method of rating power still managed 255 horses with just 9:1 compression. An original LT-1 would be an excellent engine if you didn't mind the high compression of the 1970 version. It is also a VERY strong base for building a much more powerful engine. The power figures I'm quoting are out of my 1973 Chilton's Manual. I have also driven and raced vehicles with the 11:1 LT-1 back in the early 70s when there were a few on the streets. I also realize the original post was most likely about the newer LT1 but just imagine, if you didn't have to meet emissions, what fun a 6000 rpm solid-liftered small block could be.
jms

my thoughts exactly jms. I wouldnt have said it just to be a wanker!

Kory, I did this swap (LT1) and wanted to keep my AC, so on the front of the crossmember just above the engine mount, you have to notch about a 3 inch wide by 2 inch deep hole into it. but dont make the mistake I did, you have to weld 1/4 steel into the hole, not 1/2, I had to grind most of mine down on the bottom. e-mail me and I can probably get some photos for you if this was confusing
