Dont mind me, but dont the newer 5.3s share many of the same bolt patterns and designs as the LS1? Because last I knew many of the LS1 guys would swpa out their heads for the 5.3 truck heads because they had larger chambers, ports, and valves..

That's correct.. A 5.3 is a cast iron Gen III block.. so everything will transfer across, just as the 6.0's do.2000 Firebird.

^^ My point exactly. So you'd have an LS1 minus some displacement ;)Mustangs.. Come to the darkside...<br /><br />The dark side is the path to the shadow of greed. =DComment

Yeah compared to the LS1, which means it will feel like you have a boat anchor on the nose of your car compared to the feel right now.Originally posted by slow:

Not that I don't think this swap is a good idea; it is one of the few interesting topics in advanced tech.Matt<br />2000 Firebird<br /><br /><a href=\"http://www.fullthrottlev6.com/forums/index.php?\" target=\"_blank\">FullThrottleV6.com</a>Comment

Ok now that a v8 is actually cheaper than my turbo setup i'm thinking about going the way of the 8 and selling my turbos (got a guy with a v6 mustang drooling over them so it wont be a problem to unload them ;) ). My only questions are would a stroker kit for the ls1 work with this engine, and if i switch to the lsx intake and heads what parts from the ls1 would not work in this engine. i would assume all valvetrain, the cam, and really everything to carry over giving an abundance of performance parts. the only thing i would think would be different would be the exhaust and some accessories (basically external engine differences).2001 Arctic White Firebird With Black Drop Top<br /><br />3:42 Gears<br />Zexel LSD<br />BMR upper A-Arms<br />Trans Am exhaust with 3\" I-pipe and cutout<br />Modified intake<br />Mecham Hood<br />Trans Go shift kit<br />Making rear control arms and panhardComment

geez...when i was not having much luck with the SC & NOS...i decided to go with one...the cheaper one...NOS...but one of my ideas was to just get the bracket kit for the SC for an LS1 and put it on a Z28...too bad those turbos wont carry over!

yeah it sucks cause i will eventually do a twin kit for the 8 if i get it but those two would be way way to small for that engine... maybe i'll be like chrysler and go crazy with a quad turbo haha. seriously though i am considering this if i coudl do a 383+ stroker it on it and if enough parts carry over from the ls1. another question do we know if the bore is the same as the ls1?2001 Arctic White Firebird With Black Drop Top<br /><br />3:42 Gears<br />Zexel LSD<br />BMR upper A-Arms<br />Trans Am exhaust with 3\" I-pipe and cutout<br />Modified intake<br />Mecham Hood<br />Trans Go shift kit<br />Making rear control arms and panhardComment

There are WAY more parts for a SBC than there are LS1's. A lot more different brands to choose from, many more different styles of heads to choose from, the list goes on and on. Also, it wouldnt be hard to put in an F-body because they will bolt up into a LT1 K-member. As for the oil pan clearance an LT1 oil pan would probably work since the LT1 is primarily just like a regular SBC. As for a 5-speed or 6 speed bolting up, a LT1 6 speed would bolt up or a 5 speed from the 3rd gen F-bodies. THey have the same bolt pattern. They're also cheaper to build than LS1's.The 5.3 is a good motor, but there's sooo many more mods for the LS1, and it would be much easier to swap in. I think the 5.3 will bolt up to a 4L60, but certainly not a 5 or 6 speed manual. Also keep in mind that the oil pan is probably to deep and would scrape because it came from a truck.<b>Black</b> 1998 Pontiac <i>Firebird</i> A-4 swap<br />271.4rwhp/259.4rwtq NA<br />13.30@102.44 <br /><a href=\"http://www.freewebs.com/wickedsix98\" target=\"_blank\">www.freewebs.com/wickedsix98</a>Comment

the 5.3 we are talking about is a gen III block just like the ls1 only not made out of aluminum and will bolt up to an ls1 k-member. if i can stroke it with kits made for the ls1 i will buy it. i think it will actually be better for me as i am a boost head and an aluminum block just makes me a little uneasy (not to sure why).2001 Arctic White Firebird With Black Drop Top<br /><br />3:42 Gears<br />Zexel LSD<br />BMR upper A-Arms<br />Trans Am exhaust with 3\" I-pipe and cutout<br />Modified intake<br />Mecham Hood<br />Trans Go shift kit<br />Making rear control arms and panhardComment

wait even the 6.0 is cheap as heell if you want to build it from the ground up, http://cgi.ebay.com/ebaymotors/ws/eB...spagename=WDVW . one exactly like that sold for slightly over 500! i am so going this rout now. I will keep working on the rest of the post turbo part of my twin turbo system and keep what can be reused from the pre turbo part of the system so i wont have much work to do to turbo the v8 after i get it up and running. I am so stoked right now.
Do you think this stroker kit would work with the 6.0L LQ4 block? http://www.rsbmotorsports.net/produc...f_id=BRA%2D427 something about the #427 that puts a big smile on my face :D but a 383 would still keep me happy.

I read in a magazine where this guy had a 402 crate motor with forged internals, 5 angle valve job, a hot cam, forced induction (believe it was a supercharger, dont' remember the specs) and a 6 speed. He had 675 brake hp. AND claimed he still could get 20 mpg at 70 mph on the freeway. With a say a .8 overdrive gear in the sixth slot.... do ya'll think its possible? I'm tempted to say yes b/c the 350 CI is easy to get 20 mpg out of in the c5... and the 402 isn't toooo much bigger. What ya'll think?Now, how badly do YOU want to see my brake lights?<br /><br />Pacesetter headers, 3 inch y pipe, high flow cat, magnaflow catback, many suspension mods, intake, built a4 with 3200 torque converter, 5 angle head job, dis 4, firewires, etc etc....Comment

the way you describe that engine i would say that 20mpg would be a pretty big stretch plus is this a gen I, II, or III block? makes a big difference.2001 Arctic White Firebird With Black Drop Top<br /><br />3:42 Gears<br />Zexel LSD<br />BMR upper A-Arms<br />Trans Am exhaust with 3\" I-pipe and cutout<br />Modified intake<br />Mecham Hood<br />Trans Go shift kit<br />Making rear control arms and panhardComment

If I'm not mistaken, the LT1 is not a gen III small block, so I'm not sure about that.Originally posted by WickEdSix9838:

I missed this thread back then, but this swap seems very unique and attractive for my pocketbook. The only thing I'd be worried about it the weight.
If you think about it, some of the higher boost S/C and Turbo'd cars have iron engines swapped in. It's an awesome idea for a S/C'd 327 with a 6 speed in a 4th gen. :D
This thread is making me think, I'm going to visit some truck forums and see how these things handle boost. :D2001 Black Z28 M6<br />Sprayed, slotted, geared and more~Comment
