I just wanted to know a little bit of technical info about the l83 engine. I would want somebody to fact check this.

Like the LS engines, LT engines are also the same dimensions. So the 5.3 has the same dimensions and crank bolts etc. So is the 5.3 8 bolt too? Has anyone checked? The reason i ask is to mount the correct flywheel and clutch combo..for a manual.

Do any one of you guys run headers? Are there any out there for this swap? I do see a lot of truck headers and camaro headers but i am sure if they will fit older cars?

Do they make a mechanical/belt driven vacuum pump for the 6.0L LQ9? I know I could go and get an electric vacuum pump, but would like to try to keep it a bit more clean and considering a belt driven unit, if that is a thing....

So did you get it running and the vacuum measured yet? I'm really wanting to remove this pump.

Hello. I have been busy painting the 69 Camaro. I went with the LT1 intake, it has the port for power brake vacuum as the LS type intakes. I won't be able to measure the truck intake vacuum. I did turn the engine on with the truck intake and the vacuum at the emissions fumes valve is very strong. I have no doubt it will be enough for power brake booster.

Good luck.

Default 6L80e in a 1969 Camaro

Very little information is available with regards to the 6L80 in first gen Camaros. I was able to fit my L83/6L80 combo in my 69 Camaro. No cutting of the floor. I made some minor changes to the firewall (small endentation to give the high pressure fuel pump guard bracket clearance), I moved the fuel injector wire plugs off their brackets and against the intake, and hammer up the metal slightly at the middle very front area of the transmission tunnel. The original subframe and engine tower were modified to accept the engine.
