TSP 454 LSx, what cam?

$5095 for basic shortblock from TSP...
with upgraded Callies crank and Oliver billet rods, $6100.
VERY good price for 454 cubes.
Why choke this motor with L92 heads? Get some ETP's or LS7's that are ported to 390-400 cfm. Make sure to get killer valvetrain, and spin it to 7500 rpm and make 750 crank hp!!!!!!!!!!!!!!!

6k shortblock
3k et 240cc heads
2k valvetrain from springs to rockers to pushrods to timing chain to lifters ect
5k itb intake 0r 3k sheetmetal intake+TB (id rather the itb's)
add another 1k-2k for random crap like injectors, fuel rail, gaskets and covers, plus a nice ned deep oil pan
750 for a ***** out tune

If you use L92 heads and an L76 intake, you may have 454 cubic inches, but you won't have 454 cubes to use. Its a waste of cubes to use those heads and intake. You won't make any more power than a 422 or 427 with the same heads and intake. Hell a 427 is too many cubes for those heads and intake.

As far as $$ goes I'm just seeing what it's going to take first then go from there. If it ever does happen I'm well aware that it'll take some money and time to configure the setup right.
It's just hard to say what will work right now with no real hands on time from anyone. I'm sure in the next few months if not weeks we'll see what will work and what won't

what bore and stroke are you using to make this 454ci? If this is an LSX block, I'll just put and LS7 top end on this block, should make some good power. I am thinking about something similar myself.

i cant imagine what the tall deck 500ci lsx motor will cost when you need custom everything
So you guys are saying that an LS7 top end want get the job done with this 454ci engine? I personally think it will be enough, take a look at BBC heads flow numbers. On a big bore say 4.200 or 4.250 this 454ci engine should make around 25-50 more horsepower.

it might get the job done, but not well
On anything over 440cid, I'd really look into something as close as possible to a 260+ duration hydraulic cam. Especially if the bore is 4.200" as it is on the LSx. I ran a 447 and a 260/260 114. It was like driving a 346 with a 220/224 and it had LS6 heads and still made 580rwhp and 545rwtq with only 11.2:1 CR. You have to just about throw everything out the window about the LS1 when you step up to these size engines.
Also, the LS7 topend (untouched) would probably be the best bet from what I've seen. The LS7 is nearly too much head for the 4.125" bore and 427cid. It'd be perfect for this size motor in a street package.
The reason I chose the 257/266 is because that's what TSP has and will offer you. It'll work too. In a 408, it's too much, but the difference between a 454 and a 408 is actually much bigger than the difference between a 346 and 408 (though the cid displacement is similar). The bore increase is far greater on the 408 to 454. Just look at what opening the bore to 4.125" does. Before the 402s were the rage, people actually built 427s and they did outpower the 408s very easily with similar cam and head packages.
