Big Block Chev not much problem at all, just make sure you upgrade suspention & BRAKES to suit you may want a better/ stronger G-box & diffs as well

edit: you guys were too quick and replied while i was writing this.

@seehuusen, 383 is (typically) only a small block.

you read my mind smokey, im on the shop for a big block chev at the moment. i read some magazines the other day with some dyno sheets and ive seen the light lol.

sounds like you can answer a few general questions for me. ive done a quick google search, seems they have the same gearbox bolt pattern and engine mounts as a small block. so if a small block was in the engine bay, a big block will bolt up in its place? do you know if they share flywheels, i have all new small block chev flywheel and clutch etc here, wonder if they would bolt straight on to a big block.

how much can you get a big block for? i really want one!

to answer your questions, havent heard of one in an MQ. searching google i found a bloke with one in a GQ, but not a lot of info on it. I have heard from a guy round the corner from me thats done many V8 engine conversions on both MQ and GQ that MQ have a lot more room and are easier to fit a big engine into, so thats good news.

MY-TD6i makes valid points about the gearbox and diff strength, however my personal intentions are for a nicely reco big block with all new manifold etc to 'refine' it, but not necessarily make extra power. i reckon the stock parts would hold up okay then.

with regards to the brakes and springs, i wouldnt worry about it. ive heard the SD33 weighs a bit more than a small block, and a big block weighs a bit more than a small block, so its all good imo.

Both engines are similar in weight as the sd 33 weights 600 plus and the big block Engine Weight FYI

dry weight of an SD33T is not 600KG plus!!!
It's 305Kg dry and I've had my engine out 3 times in the past 2 years... I guarantee my engine hoist can't lift 600+ kgs LOL

in comparison, a 7.2 liter Duramax V8 diesel weighs 1180lbs or 535Kgs and a TD42 is 352Kgs (someone actually put their engine on a set of scales on outer limits TOP NOTCH!! LOL

Big blocks start at about the 427ci mark..... 350/383/400s are still small blocks. Chevrolet originally had their Big Block starting at 348ci but as their small block grew from 265ci to 350ci the smallest big block was the 427 and the starting point for 'big block' V8s is recognised as 427ci.

The recognised BB chevs are 427, 440, 454, 470, 496, 502, 540, 572 and a few other variants. The original 1955 big blocks were 348 to 502ci.

With the USD at the moment you can get a complete GM factory rebuilt 572 with the race block 4340 crank and every option making 620hp for $14k delivered. *Drool*

Stop talking about Duramax engines, everytime I buy a Lotto ticket of late it turns into a Duramax in front of my eyes.
Sweet sweet diesel power, do want!

540 RealStreet High Performance Chevy Big Block Crate Engine
540ci, all new parts including block, forged internals etc, 625hp @ 5200rpm, 640lbs @ 4000rpm, runs on 91 octane! $10k to buy, $1200 sea freight.

im shopping for a stock big block for now, then im going to hot it up with some bolt on parts and i should be laughing. should get 500ftlbs and cost only a few k. far superior option to duramax imo, i could build 3 big block wheel standing MQs for the price people buy 1 duramax engine.

@seehuusen, ive been doing some reading on aussiev8.com and there were a few people who had discussed big blocks into kingswoods, pretty sure they were QLD too. they were saying for seperate chassis vehicles like a 1-ton, the max ci size engine is the weight x 0.33. for a sedan with a uni-body chassis, its weight x 0.29.

so for a MQ to only be able to have max 350ci means 350/0.33=1060kg! i think the MQ is a bit heavier :)
1500 * 0.33 = 495ci
1800 * 0.33 = 594ci
2000 * 0.33 = 660ci
not sure if there is other reasons for the 350 limit, but the above is what i read from people doing conversions.
