ls3 callaway or ls7 engine?
San





For that matter, an LS3 can be supercharged, too, if it needs more power. Or twin turbo a la STS.
Yes im planning on stick the ls3 callaway engine in a 69 camaro and just want it to be able to do 160mph with ease and possible be able to do more if i ever have to put my foot to the floor

I have been trying to find some information on what the 580hp callaway engine tops out at however i cant find an article where anyone has tested one.
Thanks for all your help and i will be using a t56 6 speed maual will that be able to take the force from the engine or will i need a tremec6060 6 speed?
Also theres another question i have im guessing that a 69 camaro or any 60s muscle car(chevelle,mustang,shelby,camaro,corve tte) weights alot more than a new 08 09 corvette im guessing?
Its just ive been looking at howmuch 60s muscle cars weighted and the new cars weight and they are along the same lines from what research i have done.
Or am i just wrong which i think i must be.
Also if anyone can help me what do callaway do to the ls3 to allow it to run a supercharger different pistons? If i contact gmpp and buy a new crate ls3 engine what then do i have to buy to turn it into the ls3 callaway i know i need the supercharger but will i need to buy the liquid to air intercoolers different pistons to run the supercharger different cam? would i be best buying just and ls3 block and building it up as i go sort to speak?
Does anyone have the specs on this engine they could give me.
Sorry everyone for the questions but i just want to make sure i take the right path as i dont want to buy something that wont do what i want it to.
I appreciate all your help and think your advice is brilliant
Sorry for the long post and lots of questions.
Have a great day everyone

Not trying to confuse you but have you ever looked at the Mast Motor engines. They have a 427 CI LS3 @ 618 hp and they just started making some Magnacharger Motors in the 750-800 range. They also sell the chip's to make A6's work! I did not see the new Magnachargers on the website yet but I know they are making them. You might expand your search a little and these are good guys!

At 160 mph, areodynamics plays a bigger role than weight. You might also start looking into whether areodynamic mods are available if you want the car to be stable at 160 mph.
There are enough S/C 600 rwhp LS3 cars out there that a piston swap probably isn't needed to achieve your goal.
I'd still vote for an LS7 or similar 427 build.
A nice 427 will easily put down 550 rwhp and with the right gearing you will hit your target.One last thought: There are a lot of LSx swaps into 1st Gen Camaros out there. They can tell you what works (e.g. you may need an F-body oil pan rather than a vette oil pan, etc) and what results you get at given power levels. There are better boards to help you.

I did a similar type sway by putting an entire LT1 with A4 into a 67 Cutlass. We dropped well over 200 lbs off the front end and had to put lighter springs in the front. I sure you will probaly go with a new subframe but the new Ls3 is going to be lighter than the Iron 327-396. Lots of fun!

Thanks for all the information.
I have been looking at the callaway ls3 engine however after some thought i have woundered if i should play it safe and go for the ls7.
If i plan on installing the ls7 in the 69 camaro i would run the dry sump set up like in the new vets, surely thats better than wet sump?
I found something funny a couple of days ago a friend of mine showed me a clip of a 67 shelby gt500 super snake i think doing 150mph and reached speeds of 170mph with a 427 sideoiler in it and thats back in 67

So surely if a shelby did it with a fe427 sideoielr surely a 69 camaro with an ls7 would beat that easy right?
I mean the 67 shelby doesnt have better aero dynamics that the 69 camaro i would of thought?
Cheers guys for all your information and i will check out the ls3 427 builds
cheers guys
Have a good day
Dave

p.s This sounds childish but i saw the new transformers film last night and the concept corvette stingray
is awsome i hope it makes production





Otherwise you could be throwing a lot of money down the toilet and wind up with nothing---nothing worth having, and nothing anyone want s to pay money for.
Just my opinion.
On any car, you will be flooring it to get to 160 mph even if it was a 6 cyl. or a Viper. I wish you luck.
I myself am not sure which one to pick i must admit i like the whine of the superchargers my self however if i buy a stock ls3 engine from gm what do i need then on top of that to make the callaway engine is it just the supercharger they put on it i think i remember reading that it was a liquid to air intercooler and some other stuff so what would the cost of all those mods be?
Plus does anyone no what the 580hp callaway vet tops out at? anyone have one that could chip in and say what the performance is like?
Plus if i pick the ls7 is it still avaliable i remember hearing that gm was going to stop producing the engine due to costs?
Thanks everyone in advance.

I havent' topped out the 590 Callaway C6 (just got it yesterday), but I can tell you it is an absolute beast. For comparison's sake, I hit 180 mph on many occasions with my 480 fwhp C5 Vette. This new C6 Callaway will easily surpass that.
