Hey guys, thanks for all the pics, here are some of my swap, hope you like, comments please.

dan42 · 10-06-2008, 03:38 PM

Try again - love to see them.

70rs/ss · 10-06-2008, 03:40 PM

The picts aren't showing up? I have one languishing away in storage waiting for me to get to it. I started this swap 4 or 5 years ago and the LS was still spendy, then I bought a 6.0/4l80e and sold it before I swapped it. The LT1 is too easy to do and super cheap, still usues most GEN I SBC stuff (well, one piece rear main SBC, crank, rods, etc, etc) so they are simpler to work on and less of a hassle, especially if the swap is about driveability and dependability. For all out power, the LS series is a better foundation, but the LT1/4 is not junk by any means and the ones I see here are sweet! Makes me want to get my swap in gear!

Hey I have a 1967 step side and putting a LT1 in it I was trying to find motor mounts or how people are mounting them?

Use the 6 cylinder mounts and bolt them up. No distributor in the back to get in the way.

6772owner · 10-09-2008, 11:33 AM

**schwoch1** · 10-09-2008, 12:16 PM

Got one in my '71 GMC, been driving the daylights out of it this summer. I kinda hacked the factory harness out of a Caprice to work in the truck, it is not pretty, but very functional. Someday I am going to clean up the harness and make it look presentable. What is everyone doing for the fuel pump???? I get the same question, why not an LS1, my answer, if you pay for it, I will put it in. I picked up the LT1 complete with harness, accesories and transmission for a song!!!

6772owner · 10-09-2008, 12:33 PM

Hey schwoch1 sounds awesome man, I havent even fired mine yet, so im pretty anxiuos. Im using the MSD inline electric fuel pump on mine, but again, havent even started it yet.

70rs/ss · 10-09-2008, 05:13 PM

Looking sweet, did it come from a Camaro?? Mine is out of a Caprice, but I picked up a set of Vette heads on the bay for pennies, so I am ready to go, just can't decide if I want to do the 350 as is or stroke it to 383 before I start?! I want a DD with decent MPG, but I also know there is a ton of power being left on the table leaving it as a 350.

6772owner · 10-09-2008, 05:52 PM

Yes mine is from a 96' Camaro, I already had a 700R4 in the truck, so just bolted it up to that. Yeah I want to do a stroked LT1/4 with it someday

6772owner · 11-04-2008, 05:04 PM

Ok guys here we go again, I have some updated pics of my LT1 swap. Hope its ok to post them here.

6772owner · 11-04-2008, 05:50 PM

Here a few more.....

70rs/ss · 11-04-2008, 07:02 PM

Very nice, I am glad I haven't tossed my LT yet. I've had a lot of thinking and rethinking on it and I am just not with the LS crowd to the point of ignoring the LT's (I have one of both!)

6772owner · 11-05-2008, 10:30 AM

Well thank you 70rs/ss it has been a lot of work. I think that both engines are awesome, and have their place, its just about your budget

**lock** · 02-04-2010, 03:03 PM

svgould, what headers did you use... and are the D-port and long tube?

Thanks

My headers are a mid-length camaro header with d-port gaskets. No problems with them at all.

lil blue · 08-10-2010, 09:53 PM

lt1 sounds better when u get a ls in the higher rpms its really poppy that the only reason i dont like ls other then that ls is a better motor over all

63chevyll · 08-10-2010, 10:21 PM

i have one sittind under my bench. trying to find something to put it in

lil blue · 08-10-2010, 10:22 PM

I have a 383 LT1 I built for a 93 Trans Am I used to have. If I ever put it in something I'll let you know how it compares to a stock one

. They dont have as much power as a LS stock but they are still fun to drive. The only thing I dont like is it seems all the LT1 specific stuff costs $500.00.

My set up is pretty mild but should have no problem planting me in the seat.
bored 30, 12.5:1 compression
Balanced Scat crank, and rods, hyper pistons.
LT4 Hot cam kit.
stock aluminum heads (might upgrade to LT4 heads if I find a deal)
new GM 4L60 with 4.3 Torque converter (higher stall on the cheap)
I will run a 3:73 gear the A4 likes this best, manuals like 4:10's

I am still have the harness and ECM so I will make that work. The guy who bought the TA put a big block in it. I kept most of the the misc stuff I will need for a swap.

iceship · 05-27-2014, 08:18 PM

is your ac pcm controled or from your factory harness. .
