Heads are all the same design. Totally different CR's and bench flow rates. We put 5.3 heads on 5.7s all the time. Comes out to 10.9 CR which is a nice bump from stock 10.2. The LS6 heads flow the best out of the box and have lighter exhaust valves (sodium filled). While the 6.0 heads are a close second and are ideal for FI motors and are a reasonably priced head compared to the LS6 heads...

subscribing to this thread too. Lots of good info. Some one mentioned ls1 tech on another thread. Tons of info there and a special forum for people doing conversions. Linkity link link

However, the way I read your statement was that for instance, I could use a 4.8L (LR4) crank and rods in a 6.0L (LQ4) block and it's a bolt in. Also, I am not sure how you're seeing motors with stock CR of 10.1? From my GM Tech resources website: LQ4: The displacement of the engine is 6.0 (5967CC). Compression ration is 9.4 to 1. Firing order is 1-8-7-2-6-5-4-3. Bore and (X) stroke is 101.60 X 92.00mm, with a stationary 2 valves per cylinder. Rocker arm ratio 1.7. LM7 The displacement of the engine is 5.3 (5328CC). Compression ration is 9.45 to 1. Firing order is 1-8-7-2-6-5-4-3. Bore and (X) stroke is 96.01 X 92.00mm, with a stationary 2 valves per cylinder. Rocker arm ratio 1.7. LR4 The displacement of the engine is 4.8 (4807CC) Compression ration is 9.45 to 1. Firing order is 1-8-7-2-6-5-4-3. Bore and (X) stroke is 96.01 X 83.00mm, with a stationary 2 valves per cylinder. Rocker arm ratio 1.7. BTW, Nice R1. I have a 2003 R1 SE. 162hp at the rear wheel :p Last edited by FormerMember; 10-19-2004 at 05:00 PM. |

Right on. The only experiences I have is using LS6 cranks in 6.0 block builds and 6.0 cranks in 5.7 builds. I guess the 4.8 is an odd ball stroke. Not sure why anyone would build a 4.8 just sounds to close to a 4.6 and we all know those are worthless motors haha...
Gotta love these bikes, such cheap power. Mine put down 154 rwhp with some tweaks. Good enough for me!

Actually, the GM 4.8L makes decent power: 275 HP @ 5200 RPM 290 ft-lb@4000 RPM You can buy them cheaply and do some of the same mods. Pretty close to the 5.3L but we all know what the 5.3L can be made to do. I have a full TI Akrapovic exhaust, GYT-R cams, ram air, PC3R and a few other things... bike screams! |

Yeah I was just saying it to take a cheap shot at the mustang boys.
So when are you putting a lil turbo on your bike? I've been dying to that ever since I saw one in Houston...

It's the 5.3L mentioned above, engine designation is a LM7 not truly an LS1. LS1 is an Aluminum block, 5.7L with the same fuel injection. |

woa woa, why hasn't the forum been emailing me? this thread got away from me
![]() ok, I'm up to date now. I've been spending some time on www.ls1tech.com also, it has a "hybrids" category that feeds this interest well as well, I'm also spending time on FSC cos I DD a 2003 Z71 and they have good info too since they work on these engines. not tryin to advertise for other forums!! just tryin to help people get the info I've gotten to make this easier for everyone. So, from what yall are saying about the ls1 and vortec engines.. would it be any advantage to swap out the stock 5.3 heads to some stock ls6 heads? I iamgine you can get them cheaper than the mongose street heads for the ls1s that AFR makes.. $2500.. ouch for those of you considering the vortec engines let me just make a comment that I found out the hard way lol, the intake manifold on these trucks, based on year, and state, are very different. The 99-00s have the EGR hole on the side and the Evap on top, the 5.3 (or at least mine) has an FPR on the fuel rail and 2 fuel lines going back to the tank, as such the FPR uses a vaccume line off the side of the intake manifold, if you get a 4.8 intake and try to put it on your 5.3 you will have to tap a vaccume line somewhere for this FPR, or relocate it because the 4.8 has a single fuel line system with an FPR somewhere else down the line. Also on 2003 and up the intake is different because of drive by wire, the tube that comes off the valve cover into the TB on the 99-02s was moved back to the manifold because of the throttle motor on the TB in 03+ and 2 of the 3 brass "bushings" on the top of the manifold were removed because there was no throttle cable. If youj get one of these intakes and plan to use it with a cable'd TB you will have to either ditch the tube on the TB, or flush and fill the hole on the intake (I chose the latter) and you will al;so have to get some of those brass bushings, and press them into the intake. I'm considering making like a how-to or something on this, not sure how it'll turn out but I think it'd be of an advantage to make a sticky in the not so distant future on this ls1/vortec/ls2/lt1 whatever else.. swap heh Last edited by DarkFox1; 12-03-2004 at 11:26 AM. |

There is a tremendous amount of advice about this stuff over at www.camaroz28.com, message board for lt1 and ls1 especially.
I am a member of that board as well and it is a very active community over there.

just kinda bumpin to see how everyones doin.
I've got the motor pretty much assembled, I have to tap a vaccume for my FPR since like a dummy I got a 4.8 manifold on a 5.3 motor. Learn as you go eh? heh. I've found yall.. for those of you planning to use a GM stock fuel pump but finding the silverado one is a few.. feet.. too deep. GM part # 10355739 is a flex-fuel GM stock fuel pump from a 2004 tahoe 5.3 its about 9" tall with a 4" opening (.5 ring around that so 4.5" total diameter on the top) has only 2 tubes on it instead of the 3 the silverado has, and can be compressed with the springs integrated into the system down to about 7.5" tall. I plan to use one in my project. I've been running into a lot of trouble as far as instrumentation here yall. From what I've seen.. you either have to have double sensors on the motors so that normal guages can read them, or you gotta use stock wiring. I'm leaning towards the latter since I'm working with the stock wirting all the time now, it shouldnt' be aproblem. Just fool the wiring into thinking its in a silverado and everything should be fine. One thing that puzzles me tho is the fact that to use stock instrumentation yo uneed to use the silverado guage faceplte.. which.. doesn't exactly fit in the stock dash. I know jeremys doin somethin like retrofitting the dash into a glovebox. Also an option for me, but.. what I'm considering tho.. and this is a STRETCH of an idea.. but.. taking the stock silverado guage assemblies apart.. and putting them inside the stock c10 guages? just a thougth yall. |

I was just going to suggest the same thing, you might have to repaint the numbers or get some printed off the computer, but I cant see any reason why it wouldnt work, do any of y'all find a problem with that?

Re: 5.3 SSR Engine Installed with 4L60E
Are any of your guys running the Edelbrock Air Gap 4 barrel intake w/msd ignition control that they make for the LS series motors? It comes with a TV cable bracket for the 700R4 or 460L. This is what I think I am going to do. I don't want all the computer and hassle of wiring the thing up.

Re: 5.3 SSR Engine Installed with 4L60E
The eddy intake works well, victor jr. is better though. And the Ignition control that comes with the intake is ok, but if you get the MSD version you can control all the timing maps on your laptop
