Which LS Engine?

[kiwigt]

I'm starting the build of a 69 Camaro that I'd like to be sort of an 'iron fist in a velvet glove' - an AMG Camaro if you get my drift. A somewhat luxurious PT car, with the emphasis on the touring part of the equation.

I'm committed to the full DSE catalogue, and the car must be auto gearbox.

I want a new crate LS engine; about 550-650fwhp I guess. Engine has to be run by a GM computer - no other setups such as Mast etc.

If money wasn't the determining factor, which LS engine/auto gearbox combo would you recommend for what I'm trying to achieve?

Oh the irony of me being the first one to post on this thread. :rofl: How about 700hp?


Guys, the reason I'm even considering the supercharged LSx 376 is because I fell in love with this engine that Greg Weld had to put into his 62. There is no denying the beauty of this supercharged look.

Hmm. Maybe wait a bit for the LT9 or whatever they end up calling the supercharged version of the new direct injection LT1 when it comes out :D

Love that engine...I've already repeatedly returned to that post for more looks....

LSA with paddle shifted 6l80e, plus you get a warranty!

I've been following the Lou's Change build LSA swap on here closely, I like the idea...

Are 6L80's becoming common now in first gens ?....there doesn't seem to be that much on the forums about a heap of people doing it...

I have to say I like the idea of a factory paddle shifter in a PT car. I really like the paddle shifter in my daily driver c6. The only negative I've seen about the LSA is the factory redline which is 6000?

I'll also tell you this now before you spend 150k. If you have mercedes benz on your mind when you build a PT Car, you are in for a rude awakening on your first drive. It's a 40 year old car with 40 year old basic engineering, it can't be done.

Thanks. I've built many cars (myself) over the years and have the PT disease firmly in my blood, so I feel I'm approaching this with a fair dose of reality. Many of my previous cars have been fairly hard edged, and I was trying to convey in my post that I'm not looking for every last dose of horsepower (been there) but more looking to create an overall balanced and driveable touring package, while retaining what we all value - the '40 year old car' bit....

Understand, I've been down that road myself. I was wrong about the LSA, it's 6600.

Re the paddle shifter - The 'connect and cruise' LSA crate package comes with a 4L80E. I assume if you use a compushift setup you could paddle shift or use a G8 shifter - I would really like a tap shifter such as the G8 setup

that is because most guys want manual. 6l80 will also definitely require tunnel surgery.

Way to go Debbie Downer. I'm so happy you said it first and not me. That was the first thing on my mind. My new GT500 feels like a Rolls Royce after a long drive in my Camaro (DSE frame and quadralink). Don't get me wrong, the Camaro actually rides smoother over bumps than the GT500, but the Camaro is 40 years old and despite some sound deadening and good dampers, it still feels like you got out of a washing machine after a two hour drive. That might be partly to do with the engine though. If I were you, I would definitely go factory LSA for something smooth, reliable, and tame until you put your foot down. With lots of Dynamat, plus lizard skin spray on heat and sound deadener, plus that sound padding under carpets (I've got that stuff in mine), you might be able to make a quiet car. Also, forget about loud exhaust, and long tube headers. In my opinion, if you focus on eliminating the noise and vibration from a big cammed LS3 engine, you might come close to making a car that is at least on par with a new Ford Focus. :lol: Getting an old car to those levels of refinement would probably make you feel like you were in a Mercedes Benz. At least that's how I'd feel. It would be quite an accomplishment.

I don't know about the GM automatic transmissions with paddle shifters. Maybe Todd can chime in again. I've always wondered how well they actually work. Are they quick to upshift? How about when you downshift, does it take for ever, can match revs at all? The only reason I would ever own an exotic transmission would be able to make cool rev matching downshift noises with click of paddle.

Well, my 67 RS Camaro has LS3 418 with a Harrop TVS 2300 and Bowler 4L80-E transmission. The 4L80-E fits in with no modifications to the factory transmission tunnel. If you plan on a 6L80-E, then you have to modify the transmission tunnel. I seen only 1 done so far, but it is something that you must think about in your build. Mine is a paddle shifter automatic from Twist Machine. Mine should be done this year, but I never built it to be smooth riding car.

I admit that we spent longer on the undercarriage than most pro-touring cars. Actually it was 2 years of re-working the flaws in the factory floorpan. We did some beefing the floor pan, but only a few know about. I could care less if the ride quality is poor, it is high performance car. I couldn't give up the sound of the exhaust! Todd expected that it to ride and be quiet as a Mercedes Benz? Hmmm, Todd hasn't been on the Autobahn! He would have a rude awakening, but I was only in a rental VW Golf. Todd, it only goes 120 mph.

Hey Todd, I have a friend that is a former F-15C fighter pilot, but he refuses to fly in propeller planes anymore since he has flown in fighters.. Ummm, they are rather loud too. It might hurt your ear drums a bit. He is into Camaro's too, but not sure about Mercedes Benz!

How bout this for way out in left field? Pull a engine and trans out of wrecked SL65, E63, or S63? It'd be big money, but you won't find anything much smoother and crazy sounding. Plus- who has that?
