Well I finally decided to attempt the swap. I can't even count how many articles I have read about ls engines and transplanting but I think the more I read the more indecisive I become about the best way to do it. I think everyone agrees I'm nuts for trying but you can't win if you don't try right..... So I have a base '78 V-8 Camaro that I traded a '68 Dodge Coronet in 1996 when I was 15 years old lol I could only legally drive it at the local drag strip The Camaro was going to replace the dodge as a track only car but then I was convinced to "fix it" make it street legal. With my older cousin’s help and the use of a local machine shop we built a balanced 454 and an old school Muncie 4-speed out of left over parts he had from the 60's. The car was awesome but after owning my '01 WS-6 T/A M6 I wanted the Camaro to be able to do more than make lots of wonderful noise in a straight line. I installed QA-1 coil overs and upgraded to Nitto K555 275/35/ZR18 front and 295/45ZR18 rear tires. The performance improvement from a wheel & tire upgrade is amazing! Now that I could push through the corners I realized how weak my brakes were.. I installed some hawk street pads that fixed the fade issues but I still had an overall lack of stopping power. I figured that the solid lifter cam in the 454 was a little on the large side so I installed a vacuum canister. This was great for one or two pumps of the pedal then it was same old same old. According to the gauge it only pulls 5lbs at idle. I decided to upgrade to a hydroboost setup problem solved The one problem that I never could lick was the amount of heat the 454 created. I tried every trick every combo known to man no dice. So....I decided that it's time to shelve the big block and swap in some new tech. My goal is to have similar power with a cool running engine freezing cold A/C and some sort of O/D transmission. In Texas we have lots of wonderful sunshine but along with that is the 105+ ambient temps and a scorching big block with long tube headers and no A/C is just not acceptable. I started this project at 16 and I just turned 35 so I decided to punt and leave the old school muscle for one last revision of the Camaro. As a teen I always dreamed of a twin turbo big block Camaro running around town looking for mustangs to devour but now that I'm a little older I would rather build a more balanced car weight wise that can actually handle like a modern vehicle and not a drag car. This is the first thread I have posted in my life so I hope I don't offend anyone if I am not posting the correct area. I would like to get opinions on best combos engine, trans, brackets, accessories, controllers efi & ignition, cam, intake etc. for the swap. I purchased a long block 6.0 LQ9 out of an '04 Cadillac Escalade it had 140K on the clock. I also recently purchased a running 5.3 with a 4l60e (I believe) out of a 2000 Suburban full harness and computer all accessories from air box to drive shaft. I would like to have a T56 mag someday but I will be more than happy if I can make the 4L60 work for now. I have a fresh 12-bolt posi rear with 3.55:1 gearing. Any advise / help is appreciated more than you know! Cheers!
