Why aren't there any aftermarket LT1 Blocks?

Just because the guys don't post here, doesn't mean they aren't "out there". They are. No $3000.00 heads, either. Last pull on mine was 522, another customer with a "mail order tune" made 521. Both have non-lock up 4400 converters and 4l60Es. Mine has LT4 heads & intake, his has LT1s. None costs as much as you indicated. A couple others right at 510 rwhp.

What's the highest HR N/A pump gas setup youve seen? I think Ive heard of 1 or 2 in the 470 range but it seems like people who get to that point drop the HR setup and start getting deep.

I was 486 rwhp with a hydraulic, drove it to Nobile, near OKC to run it (right at 120 miles each way). Ran me off after one pass because I had no roll cage in it yet. Hoped they would not notice for a few passes. Couple of weeks later a rocker stud broke (should have use ARP, instead of GM) and a lifter came out, turned 90 deg, and ate the cam. Went solid rollers after that. If you do it correctly, valve lash stays put very well. No more RPM than the factory PCM will allow, you should never hurt one of these things. Loose a bearing with a stock PCM, you really screwed up someplace building it.

it used to be LS1s were too expensive to make good power. now its the other way around. if you want an LT1 to make 500 rwhp you're going to have to spend $3000 on heads and another $1500 converting a single plane over.
Now 500RWHP you are correct it's going to cost you more.... But don't think for a second that those LS1 guys are running 1500 dollar heads and making 500RWHP..... guaranteed those heads are running them 3g's easy.... if not cores then the work into them will make it to 3g's.... Intake swaps yeah you're going to have 1500 in an intake.... but I think a single plane victor will outflow a FAST 90/90 anyday setup right... I don't think anyone's arguing that the LS1 is a superior motor stock for stock... But a properly setup LT1 will even the playing field when money becomes involved...
I don't keep any secrets about how much money will be involved in my setup.... most likely close to 15K in the motor.... It's an easy number to get to when the rotating assy is just shy of 5K, heads are 3K, valvetrain easily approaches 2000 to include cam/lifters/pushrods/shaft rockers. The intake will go about a grand completely done (direct port NOT included)... then you have misc stuff like 4 bolt splayed mains, good rings/bearings/gaskets..... Fabricated valve covers, balancer, dist, crank trigger...... we're almost at 13K now and we haven't even discussed labor, machine work, or how to CONTROL the engine (XFI,DFI,BS3)..... but these are not just LT1 specific issues.... Ask WormBoy how much he has in his LS1 and I guarantee you my number will PALE in comparison.... when you play, you WILL pay.... and the harder you want to play IE Sub 8.0, sub 9.0, Sub 10.0, etc will dictate how hard your wallet gets hit.... regardless of motor, make, model, FWD,RWD, 4 doors or two....

you can make anything fast.
and if you know the right people, and have the right info, you can make it fast, cheaper then the other guy.
that applies everywhere in this thread. from the "LT1 vs LT1" argument above, to the "LT1 vs LS1" debate also going in this thread...
