Stuff you need to switch over to an LSX platform.

Thats the one I have been looking at . If I can't find a deal on the intake I will go this route . I saw an intake for $200 , but was too late . The MSD setup is only a little over $300 , but the intake is pretty expensive .

Kinda thinking the same thing on the nitrous plate setup too  :smile30:

I found a really low mile 5.3 here local for $500 , no core charge . Might go with the 5.3 , the 6.0s that I have been finding are $1500-1700 .

Can you run the 6.0 heads on the 5.3 ? Seems like I read somewhere that they would work .  think.gif

No, bore on the 5.3 is too small for the intake valve on the 6.0 heads. I'm going to make an attempt at porting my heads. I did it once before on some smog heads with some OUTSTANDING results. Since the 706 casting heads area a dime a dozen. I'll take a chance on ruining a pair.. LOL

Does that 5.3 come with the harness and puter?

No harness and computer , just the motor intake to pan . I am not planning to run the harness or computer so I didn't ask for a price on the rest of it .

But by the time I drive to Dallas to save a few hundred bucks it's just not worth it . I wonder if the other place will ship it down here for me .

Oh no, for $235 you have to pull the motor yourself, hence the name "Pick A Part"

Some of the ones that you posted for really cheap were high milage motors . I was hoping to get something to hone and put new rings in without having to send out to get machined .

At 120,000 I will just drop it in. 120,000 to 250,000 hone it and put it back together. WAFOBABY will get on here tonight at tell you that those motor's bottom end is good for 500,000.

I will admit I have seen some of them with crazy high miles on them , but I am planning to shot some nitrous to it , and probably more upgrades later on . I just don't want to have all the internal parts become external parts right as soon as it hits the water .

I'm gonna plastigauge and mic out mine and make sure it's all in spec, then roll with it. Something lower mileage would be better though.

Depending on the motor I find I may just do the same thing . If I get one of those nice 25k motors I will just run it . I am talking to a guy with a 240k 6.0 that I am considering , if I get that one I will do at least rings and bearings .

Got outbid on the Weiand intake, which is OK. The biggest bang for the buck is cam and springs anyway. A nice 575 lift cam and some beehive valve springs are good for a 100hp on these motors. Another 35 hp in removing all the accessories but the alternator also.

Looks like I will be going with a 5.3 , carbed with the MSD setup . I would like to pickup a used intake if anyone sees one for sale anywhere . If I cant find a intake I will be ordering the full kit to do the swap . I have some OT pipes for logs that I think I will use on it for right now , just need to find logs . Anyone know what you have to modify to use the 351c logs ? I heard you have to drill the log , another person told me to drill the head .

I was looking for some 351C logs before I built the 460 as I was considering the LS swap then, but those were about at scarce as a virgin on prom night.

Found some info on putting the 6.0 heads on a 5.3 last night. It CAN be done but it lowers the compression ratio quite a bit. If you want to turbo the crap out of engine they are a good choice. I'll be sticking with the stock heads, but massage them a little bit on the innards.

Gonna use the stock truck intake also if I stay EFI. An LS6 intake will only get about 12hp over the truck one, and the FAST another 10 on top of that AND those gains are at ridiculous RPM's. A NOS shot for less $$$$ will easily add 100hp or more at any RPM.

Read another one this morning where a dude took a stock bottom end 5.3 with a cam, push rods and a FAST intake on a 150 shot and chassis dynoed his S10 at 458hp/470 something on torque. He was at about 325hp NA at the REAR WHEELS. In a boat with no accessories, a cam with springs, should get a solid 350-370 NA with no problem.
