So, after fighting with the c10 over EVERYTHING. I finally decided to just sell it, keeping the engine and transmission. Being I have my camaro.. I am somewhat torn if I want to keep it the way that it is ... or throw the scrapped project's engine in.

So.. The two drivetrains:
Currently in the car--
489 big block chevy--makes around 630hp probably 600ftlbs of torque
-profiler 290cc heads
-10.2:1 compression
-Edelbrock fuel injection, proflo xt manifold
-2" headers
-straub roller cam(236/242 on a 109 600.600 lift)
T56 magnum transmission to a built 10 bolt that'll eventually go 9" or S60 with 4.10 or 3.89 gears.
--I have no complaints of this drive train. It's loud. It's quick. It's brutal. It's fun to drive. Not bad on gas with the double over drive either

Other drivetrain(is the grass greener?)--
Fully forged 6.0(summit pro LS kit) 370" LS--unknown power
-Fully studded and machined mains and heads--goal is 15psi or higher built specifically to do so
-LSA heads that are currently stock with BTR double springs for camshaft
-9.5:1 compression
-CTSV blower--2.45 pulley, stock lower pulley and will be using LSX concepts blower drive system
-BTR Stage 2 Turbo cam(226/231 on a 113 with 0.600/0.600 lift)
-1 7/8 headers if I decide to ditch the manifolds I currently have(possilby will keep them initially)
Built 4l80e buy a local place that does great work. 3200 stall circle D triple disk converter
Same rear diff

Which would you go with and why?

It's kind of cool to say "my car has a big block".
It kind of depends what you are going to do with the car. If just a local cruiser I'd keep the big block. Even with the T56 you might get 10-12 mpg maybe?
Having said the above the LS combo you listed sounds pretty cool. Similar hp and torque to the big block? Gas mileage with an LS will be double compared to the big block. Don't know if that is a big deal for you
I think the big plus for the LS is the weight reduction compared to big block. The LS will save 200 plus pounds? Less weight up front means a better handling car.
You can reuse the T56 on the LS wit some mods. Headers? I'd go aftermarket in a heart beat.

I would agree will almost all of your statement, lol. "Not bad on gas", What is that to you? I would imagine the LS set up would do at least 5mpg combined better

The benefit of the ls is better mpg for sure. My big block currently gets about 17 to 18 on the highway and probably 8 or 9 in town.
I should just throw the ls in a crown vic... But we have smog here

That's a tough one, If you put it in a 02 camaro the LS would slip right in. The big block would be very cool, but heavier like LS1 TJ said. I'd put the LS in the camaro and save the BB for some older car/truck.

My only issue here is freaking smog!
My camaro is a 75 so it lends itself toward the big block.. the LS though.. would make for a TON of room in the engine bay!

I have thought about going back to a auto instead of the manual in the car.. but I don't know. That 4l80 is exactly what I would want too

Dont even bother trying to fit that bbc in an f body, the amount of cutting and fabrication would not be worth it at all. Plus if you have any sort of emissions testing you’ll be screwed. You could always look for a better chassis to put it in like a chevelle or something with a full frame.

02redchevy

It's already in an F body
But I'm stuck.. I can't have anything later than a 75

Oh ok, I didn't know you had a 75 camaro,your name says 02redchevy,I just thought it would be a 4gen. Anyway, I guess if you're into corners, go with the LS it would be much lighter, If you want to go straight drop the big hairy big block in.

Actually in California, it's anything later than 1974. 1975 was the first year of widespread use of catalytic converters, so that is the dividing line for smog.

02redchevy

nope 75 and older do not need smogged

jetech

Cali.gov.'75 and older exempt
So no smog worries for the Camaro

Well, I think I've decided.. Going to go forward with the LS/4l80 swap and put a 9" in it while I'm at it... Hopefully I am not going backwards. I REALLY hope this makes the torque the big block does.
