Best bang for the buck, LSX 427,440 or 454? Hey guys,
OK, I'm planning a build on a '98-02 camaro and I want to get opinions on the best motor to put in it. I'm not going to be racing regularly, maybe an autox or two on occasion. Otherwise it's going to be a DD, NA btw also.
I've talked to the guys at LME and we talked about the 3 options I'm considering and I'm leaning toward the 440. I was told that I could change out the pistons and crank later to make a 454 if I decide to at some point, so that's cool. But since it is going to be a DD and I'm not made of money, (it's going to take a while of saving for the motor) I am still considering the 427. I know that motor has awesome potential, hell GMMG puts it in the ZL-1 & DH cars but I don't want to spend the $$$ on that and regret not going 440 or 454.
I just would like some peoples' thoughts and opinions on the smarter & best bang for the buck choice. Thanks.

LME is currently building my 440...
A 427 & 440 in an LS7 block is the same price +/- $100.00.
The 454 i would NOT put in an LS7 block, i would put that into an LSX block. But you have to ask yourself is the extra 12 cubic inches worth 120 pounds extra?..... NO.

Are you doing the LS7 or the LSX for your 440? I'm really liking the 440 idea actually. Mainly because I could always change out the pistons and crank later on to go bigger.
And LME seem to be good guys to work with, Brian answered all my questions.
LSX block is for FI, IMO.
I did the LS7 440. Wiseco Custom Pistons, Callies Rods, Compstar Crank. With a Moroso oil pan for that longer stroke clearence.
Bryan is an awesome Man! My block should be here next week!

If you don't mind me asking, how much was it? Bryan quoted me around $5900-6000 for a LSX 440. What was it for the LS7? I assume the LS7 would be more because it's an aluminum block.
& mine was some more than what he quoted you.
Also i plan on hitting mine with a 200 shot of nitrous, that will get me into the low to mid nines at full weight.
The reason i said the 454 is pointless with N/A is because you can now make power out of 12 cubic inches to make up for 120 pounds. If you were FI, then it would be worth it but still would not go 454 because of cylinder thickness. I would do an LSX 434 or 427.

There has been so many debates about spraying 440 aluminum blocks because of the stroke and the thiner cylinder thickness.
I will be spraying my 440 all day!
Yes you can spray the 427 and 440 aluminum.

Cool. I might want to look into the aluminum block then for either the 440 or 427. It would be a little lighter for one thing. But if I go the LS7 440 route, can I make that a 454 if I choose to like with the LSX 440? Sounds like an easy & obvious answer but I just want to make sure.

I like your thinking. But seriously I was dead set on the 454 but I talked to Bryan from LME. The fact that I'm going to stay NA and not race it, though maybe a autox once in a blue moon I'm thinking that the 454 would be serious overkill for the street. Would it be cool? Absolutely but I'm thinking I can get all the power that I could want in a 427 or 440. But I do want to find out if the LS7 440 can be made into a 454 by changing the pistons and crank like with the LSX 440. Anyone know the answer to that?
That way I'll have the option to go bigger if I decide to later on without having the expense of boring the block or buying a whole new one. $$$!

Whether you go with a 427, 433, 443 or even our 500 CI our sleeving will hold up to the FI applications as well as the NA applications. I think the aluminum blocks are the way to go when you can get the reinforced like we can do. We even have a FI ERL Superdeck II and the difference there is that instead of our 4.200 bore size on our 500 CI Superdeck II we go down to a 4.125 bore size and it becomes a FI 482 CI monster.

But just for ***** & grins, which place do most of you guys recommend? LME, Rapid Motorsports, TSP? Feel free to list others that you have had good experiences with as well. Thanks guys,
