Has anyone done this succesfully? I would love to have it done. I ahve been messing with a late model 8100 vortec motor. It is badass. I would be cool to look in my engine compartment and wah la a 8100 big block. It would fill the engine bay so nicely. What do you guys think?

I think it would be a great swap. I also think that people will tell you that you can make as much power or more from an LSx engine

I agree. Whats up with those 8.1's? Are they easy to tune/make power?

ironic that GM discontinues the 8.1 in light duty trucks and THEN people start getting interested in it. Raylar makes parts for it, and YES it can make power, the knowledge base is no where near what the LSx has tho.

Its a Big Block Chevy, Tall Deck at that, with Gen III electronics and a lot better cylinder head design.

450-490 ft lbs stock. I had one in my 67, broke a piston. Only weak link in the motor really. i would bet clearance under the windshield might pose a problem in a 4th gen.

How much aftermarket is there for one of them?

I heard there is a big aftermarket for them cause they are used a lot in off shore race boats. I would really care to much that it did not make all this power a lS1 makes but all I would really care about is saying I have a 8.1 big block in my car and you don't.490 ft lbs of torque from the factory will most likely be enough for what I am trying to accoplish. LOL It is a tall deck tho, it may have some clearance issuse under the cowling, but I dunno yet. I wonder if I could get some sponsors to help in aidding this project???

I thought it would really look like a Navigator motor in a Mustang, just on the Chevy side of things

Is there a Victor Jr. or that type of Intake made for that Engine, I see it with the Truck Intake all the time, and I beleive there is alot more potential there..

Isnt the 8.1L a MkIV BBC??

That would make a cool swap! 496 cubic inches of Chevy Power!!!!

It is a Gen VII, the 7.4 liter was Gen VI

Guess who was looking at using one for another swap project I decided against it in favor of a LSx.

I would have to make a custom intake to clear the SS hood and cowling. The heads have a lot of potenial, porting wise. The bottom end will need some help I hear they have weak pistons. New oil pan, maybe a dry sump if someone make one? Yea 496 ci inch big block bored and stoked would be insane to put in a Camaro. I would think it would twist the car in half. Even with subframe connectors.

Seems like alot of work for questionable power. I'm still rooting for the Duramax swap!

well i shoved a 454 bbc into a 3rd gen and i only had to buy the type 2 power steering pump since the stocker was far too big and hit stuff up front. i know ive seen bbc's dropped into 4th gens and its a little tougher job but definetly possible.

Now that is still a idea, just throwing a idea out for my mind to ponder. That thing would not fit with out a fight. Rear mount turbos for sure. Injectors if they went out would be a bitch to replace.

This is really good to hear than it is really possible than

I'm wondering how much that damn thing weighs..

i considered doing this about a year and a half ago when i blew my ls1. i could have gotten a 8.1 for the same as my 6.0 locally and wanted to but since it was my driver i didint take the time for the swap since i knew i could just thro a six liter at it and make it work. i really wanted to tho. wish i would have had the time to do it. im sure you could make a tq moster street car/truck out of one.

between 750 and 850 lbs depending on who you ask. They arent lightweights, thats for sure.

yes it could probably be done but why? better start of with a chassis car-a boat anchor I tell ya. besides killing the handling- overstessing the chassis from all the weight and torque, what a PITA to have to do that from installing it from unerneath? good luck my friend and have plenty of these ready when it wears you out! like alot of ideas - it could be done but why?

RsSean

iTrader: (27)

Well I love F-bodies, so I want to put to different motor in it besides a LS1 or so on. 8100 vortec motor or now a duramax. Spring rates can be adjusted and weight can be taken out.

Haha with my 2001 Duramax with intake/exhaust/tuner, utility body, 4 door, long bed 4x4 truck is (i would guess) in the 14s. I get 15mpg hauling a 12,000lb trailer and 17 empty (most get 20 though) and this thing weighed in at 8900lb. Could you imagine how well it would do at half that weight?

Only problem is a new crate from GM is $10,400 and an ebay motor goes for $6,000
