Re: 383 or 5.3?????????
On a budget, gen 1 is for sure the way to go. You have the stuff already and if you're not liking what your engine builder has to say, there are many rotating assemblies and short blocks online cheap

I paid $2000 to have my short block done (stock rods, crank and hyper pistons, new balancer, probably some other add-ons...), and I had him do the cam and timing set... I bolted on the rest after he inspected my heads. It seems like an expensive price tag next to some mail order or online deals, but I know for a fact that mine was gone over with a fine tooth comb, and balanced properly before I picked it up. There are probably many good cheap short blocks out there, but knowing the reputation and quality of the job I got was worth the money. If I could go back 5 years, I would have at least priced out the option of going to a 383, but at the time, I wasn't even prepared to put down 2k on a 350. |

Re: 383 or 5.3?????????
You can build a 383 on a budget. You first need to make up your mind and have a PLAN! The beauty of a 383 is it makes more TORQUE! You can get decent mileage BUT it's more fun with your foot on the floor! The engine in my truck is simple and cheap to duplicate! It rins awesome!!!!!

Re: 383 or 5.3?????????
lol.... wow all these these videos! well let me be the first to put a video of my white truck. its a 6.0 with cam only done to the motor, stock heads with full bolt-ons... did i mention it fully streetable and it weighs over 5000lbs street weight! how more reliable and powerful can you get?
here is some videos of my truck... its a 6.0 LQ4 out of a 05 Cadillac Denali... the grey truck is my friends, that truck has a LS1 with heads/cam and runs 12 flat.... and last, is one of my 11sec runs on the nitrous... by the way guys, im not bashing no ones opinion! im learning alot of this website from you all, but i do know a fair share about these new LS motors and like mentioned in previous posts, LS motors are the futures performance motors!

This is just a lively debate. I am strictly trying to stay on point. There isn't any such thing as a 5.3 with 486hp (out of the junkyard), but there also isn't any 383's for $500 with 486hp. Let's compare apples to apples. You can build a 383 for $2000, than I will take one please. The problem is he isn't doing the building. You can get a 5.3 swap for about $500. Then there are the auxillary parts. Which from what I have seen on LS1tech can be as low as $1500 including the motor. Now he won't have the power of a 383, but he can drop heads and a cam in himself. Not real difficult and make as much power as the 383 with the fuel injection. We all have a computer or we wouldn't be talking so he can easily tune it to. I am not knocking your 383, but IMO the LS motors are the wave of the future. If he isn't building the motor himself than the $2000 that you keep mentioning doesn't come into play. That is the only point I am trying to make and point out that 383 isn't a viable option when comparing the cheap LS swap. We can compare HP and then we can compare $, but we are not comparing the both in the same context when you take out the build factor. I am all ears if you have another solution. Maybe you could build his 383 for $2000? That would be a good alternative for him. C'mon help a fellow board member out! |

I'm gonna unsubscribe to this thread. It's just getting under my skin.
Good luck on your engine muscle1 and let me know which route you go. I'll be looking for your build thread. |

Re: 383 or 5.3?????????
Guys this is a good debate with good info but we must remember we all have different ideas and experiences with these motors. What works for one may not work for another. Me...I am happy with my factory 402BB.

I am sorry, but I would rather have an LS in my 1972 then a 383. So I won't mention you building me a motor again. Again sorry that you feel you need to unsuscribe to a thread based on me stating my opinion about what could be. Dave |

Re: 383 or 5.3?????????
I love the 5.3 in my 02 Tahoe 125K on it and she runs as strong as ever, I wish I had on in my 71, no sputtering old cold blooded manual choke 350, what a loss! but 383's are fun too, IMO you'll get ALOT more longevity out of the 5.3 than a stroker motor.

Re: 383 or 5.3?????????
thats strange try this one http://www.yearone.com/serverfiles/f...p?pid=CT350PC1
it's yearone's power crate 350 incase you still can't get it to work. its 400+hp/400+ftlb for 2900 doesn't include carb distributor fuel pump or waterpump but im pretty sure you have that. looks like a good deal to me and i've talked to a guy who has one and he's pretty darn happy with it just another possibility it looks nice though. late model roller cam block with 4 bolt mains and its bored 30 over |

Re: 383 or 5.3?????????
lets say you can build a new 300 hp 383 for $2500. and you can put a junkard 300 hp 5.3 in your truck for $2500. i think those are realistic numbers.
the ls engine will take much longer to get running. the 383 wont get 20mpg epensive tuning. some places charge less than $400 to cut down your harness (eliminate vats, and any unnessecary wiring or systems) that includes unlimited free retunes for when you want to change your mods. bottom line isboth are viable options depending on your goals.

They are installed everyday for less than $2500 if you bargin shop and can do the work on your own. If you go hog wild and pig crazy then you ain't going to install one of the motors for less than that. If you have a torch, welder, some wiring skills, basic handtools and common knowledge of how to install a motor there is no reason in the world you can't install a LS motor for less than $2000. This subject is just like saying a ford is better than a chevy, not everyone is going to agree. ![]() Last edited by jkade; 05-19-2009 at 08:11 PM. |

5.3 = $450-$700 if you shop around Cam = $200 all day long used with a few miles on it.

Engine Mounts = $15 factory style from and parts store New Computer tuned with everything you need = $150 (wait4meperformance) Guages = $400 new Misc (relays, painless 7 circuit fuse block for efi, connectors, air filter,etc = $300 If you have a th400 then spend another $300 and you are running driving and blowing 383's off the road (just kidding) ![]() You can knock $600 - $750 off that if you do a 4.8 or a 5.3 and you be patient and bargin shop for the parts to complete the swap. This is just my experience and maybe I got lucky. |

Re: 383 or 5.3?????????
No knocking a LT1 but they will not make the power a ls based motor will make. They are still a good choice though.

Re: 383 or 5.3?????????
how about a crate motor .
with 2000-2500 for short block. 500 dollars more for roller motor done .400 hp 440 tq order it .shipping 500 bucks drop it in swap parts which already you have here ya go 2990 roller ready to drop in http://www.yearone.com/pco/P_0407/full.asp?page=4. buy it drop it in. save for ls swap later date. gather parts needed for swap.look for deals i found easier to drive and gather parts instead of being apart. sell old parts off old engine.
