engine swap
Hey, just wondering if anyone could help me with some advice. I've looked at some member rides and builds and wondering about the LS swaps. I've got a 69 cst-10 2wd short-box and was going to update the motor to make it more driveable (I was running a big block at about 5 mpg). I bought a 1999 Silverado with a 4.8L and will be using it. My question is this...What mounts work without headaches, and do I need to change the pan. I've seen lots of mounts and adapters out there but there is usually one that is better than others, I forget the manufacturer but was leaning towards the kit that includes plates, mounts and tubular brackets. Also i've seen the adapters that move the motor forward or back, is that just to avoid pan clearance problems? Thanks in advance for your help.

Re: engine swap
I would tell you if I knew but unfortunately this one isn't anything I've had experience with. I hear that 4.8 is a sweet little motor and does very well in these trucks. I would expect that if you use the search feature you should find a few conversions. You might want to check this part of the forum:

Re: engine swap
I'll see if I can help.
1. you do not have to change the pan. 2. several vedors have the mounts and you really can't go wrong with any of them. However, please try to buy from a board sponor if possible. 3. issue areas: figure out what kind of fuel sytem is on your budget. Several options here. Also, the wire harness will have to be converted to a stand alone harness and your computer will have to flashed to run as a stand alone. However, You can get your harness and computer done for $340 (I did). I also suggest you read as much as you can here: http://67-72chevytrucks.com/vboard/f...play.php?f=206

Re: engine swap
1. I got my mounts from CPP and they bolted right in quite nicely.
2. go to lt1swap.com and you can learn to rework harness yourself for free. 3. lt1swap.com will reflash computer for around $100 and quick turnaround. 4. I got a tank out of a mid 90's chevy3500 31 gal that fits in between frame rails new with fuel pump (pm for part #'s and i can find them) for 175 delivered. 5. buy a coil of 3/8 and 5/16 fuel line and straighten it out, runs really easily inside frame rails 6. start it up and have fun! There are also multiple good discussions about upgraded radiators, as I havn't gotten to that point I don't have input All said and done my swap should total around 1500 including motor and tranny, that price also adds in a new radiator

Re: engine swap
He's got a 4x4 but these mounts are really adjustable and may work for you. A good thread in general is Crash's: http://67-72chevytrucks.com/vboard/s...d.php?t=494599

Re: engine swap
I'll also be using the 4l60e and would like mount for everything (engine and tranny). I've seen some posts where guys have had to chop their tunnels and don't want to get into that with mine, just looking to bolt in so it could be changed later with lasting effects.
