Maybe switching projects, instead of the S-10 swap, I may just plunk the 5.3 into my GS California. So the dumb question of the day is......Can I use the LS1 Camaro exhaust manifolds without modifying them to fit the frame?

Engine: 1999 5.3 from a Silverado

Stock intake
LS1 Corvette cam
Stock lower end
862 heads
LH8 Oil pan
1998 Camaro exhaust manifolds
2000 LS1 Camaro SS Torque converter
Have the S-10 engine mount system, SS396 frame mounts (car has the BBB specific frame mounts that will have to be changed out)


Car: 1969 GS California
455 Stage 1 / TH400 / 3.31 12 bolt posi
2.5" dual exhaust

Still need to get another 4L60E, fuel system mods (new stainless line, tank to engine, when I built the car), Jeep Grand Cherokee steering box & related steering components. (have the Jeep steering shaft already)

Yes I read all the S-10 and A-body threads. Just couldn't find out if the exhaust will work or not.

Thanks, Jim

Either way, I will have to buy the Plug & Play harness, just have to figure out the way to go for now. Eventually, the Buick will get a 6.2 from a GMC Truck. (Currently 7.5 CU IN of BBB power!)

I searched "F body manifolds LS S10" on Google.

Thanks Joe. I saw that one. I will have to mod them for the S10. But trying to figure out if they have to be modded for the A-Body frame. S10 and G-Body are the same. A-Body is a little different.

I've used the stock camaro manifolods on a 1964,65 and 66 chevelle. It depends on where the engines sits. I've seen a couple that could not get them to fit with the motor sitting in the 1" setback location. I'm not very familiar with the 69 A body differences.

I do know that the LH8 pan you have listed does not fit the A body cars very well. It hangs down WAY below the front cross-member and will hit anything in it's way. lol

Well that's not good. Already have the oil pan. Was way shorter than the stock truck version. (And needed to do the S10)
