Both engines are similar in weight as the sd 33 weights 600 plus and the big block Engine Weight FYIedit: 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.
Stop talking about Duramax engines, everytime I buy a Lotto ticket of late it turns into a Duramax in front of my eyes.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
