dude...LT1...ugh

[Mr. Luos]

Doesn't the 383 kit leave the bore stock and increase stroke?

Either way...good luck. I know what kinda work that involves. I finally got my LSx 402 running in my Trans Am.

[blakmnoncmps]

haha yeah not in the pistons themselves he didn't really get into specifics, I was wondering the same thing. But maybe bore out some smaller spaces in the stock block, and then fill it with concrete? And I was thinking the same thing, bore it out to a 383 and stroke it...I'm trying to get as close to 500 as possible without having to resort to the bottle. I want to be able be all motor.

[CamarosRsweet94]

Yeah, I thought the 383 kit left the bore the same in the 350, it just changed the stroke to make it a 383 CID engine...

[666_speed]

wouldnt concrete under extreme heat bust? i dunno

[CamarosRsweet94]

The concrete idea is NOT smart, if i worked it probably would have already been used in an engine. All it would be is extra weight, whoever told you that is either: really stupid, full of shit, or F-ing nuts...

[blakmnoncmps]

Yeah you're all probably right, I was just wondering because he works as a mechanic and he's done all his own car engine overhauls and things like that. That's just one idea he said. I wasn't going to do it because it sounded like more trouble then it was worth.

[97cavalier]

ops sorry about the bore thing, but ya do the 383 swap and get some forged pistons incase you want the bottle

[blakmnoncmps]

I thought the LT1 pistons were already forged? or are those just the crankshaft and pushrods? But, nah I'm not really into the bottle...but I might go forced induction once the cash comes either vortec, ati, or I'm even starting to like the sound of the STS. not sure which i'll try to save bank for.

Where does this guy work as a mechanic so I can try to avoid ever having him look at my car, drive by my car, or even think about my car.

OH!, That explains why he said put concrete in the engine. Those import boys are always trying to find a replacement for displacement...

weird thing is, though, he's the one in the my opening story who has the Z28 with 450+RWHP...so that's why I was thinking he might know what he was talking about. But I guess...not?

[CamarosRsweet94]

He might know most of what he is talking about with cars, but his ideas need a little work...

i think if your going to tear the motor down you should keep in mind what you are going to do to the top of the motor... if you think ahead... buy the right cam, right pistons and set it up for a supercharger or maybe a big shot of NO i think youll get the best results. and try not to concentrate mostly on HP get some forged pistons and build a solid motor. if you build the internals right youll have a very solid base to work on top of-
I also would say do not buy cheap internal parts 1) because when they break they tend to destroy your engine 2) even if it the block or the heads survive its gonna take a lot of time and money to fix it and then your just back at square one

go with the 383 kit if your aiming to be secret about it but i think the supercharger is the the best way to get a solid car that will put out plenty of HP.

i know money issues are always tight but if i were you i would make sure you buy what you need for the enitire build at one time. when your goin that far on your car you need to put months of research behind it and get whats right not whats rumor... puls it gives you some time to save a bunch of cash

[sl1cksNsk1n1es]

ive heard the myth about the concrete... dont now if its true but you dont put concrete in the cylinders.... ive heard that you can fill the coolent passageways on some blocks to make them stronger. but i dont know just dont do it... you could build an awesome motor without that
