    Exactly. If I could build a 540 for $5k I'd have one in the car right now. That's not even counting the crank/rods/pistons, rings and bearings. Ad in all the other small BS stuff and my budget blew past $8k in a hurry, especially if your going for a roller cam.

    You can't let facts get in the way of a good story. ;)

    Yeah, I priced out the stuff I wanted to rebuild my BBC and I was over $5,000 and I wasn't going for anything crazy and hadn't factored in any machine work yet. I also priced out building an engine from scratch and that was well north of $10,000

    I priced out a SBC 421 build for my 72 with good stuff all the way through and blew by 7K before I quit looking and I already had a virgin high nickel 400 block!
    I bought a crate LS3, swapped to a cam that suits my needs, put a carb intake on it and make north of 500HP without loosening a head bolt ! I sold the EFI intake and factory cam and now have an engine matched to my needs for less $s than the crate engine costs. I have 6K ( way more money than it can be done for) in an LS3 with a total of 500 miles on it so far. I wish I had been more hotrod inginuitous (LOL) and found a junk yard short block and built from there. I was afraid to build it on my own because I didn't want to screw something up and have to start over. I am much more versed in LS tech now and am ready to build a 418 out of the LS3. I just have to blow it up first, lol.
    A person that shops around can build a solid 500+HP LS for the same price as a set of quality aftermarket BBC heads.

    I'm into my LS1 swap for $4200 right now.. Probably be right at $5k when I'm done.. But I bought a bunch of New parts when I could have gotten away with used like complete exhaust, fuel system, cooling system.. Doing the wiring myself and I paid $150 for the PCM reprogram w/ express shipping to/fro b/c I thought I would be way ahead of where I actually am.. Could have saved $50 right there alone.. lol

    I pull this off successfully, I don't think I will ever go back to a Gen 1 motor; especially after I learn from the mistakes of the first swap and can do it cheaper 2nd time around.

    Well I can tell you I paid 1100.00 for my brodix heads and 2985.00 for my dart short block through my buddys shop. He owns a machine shop here local. He is in the process of doing the CNC port work on my heads now. So in my long block I have about 4grand not even close to the 10k you think

    That's $4085, so you're saying you got an oil pan, timing cover, timing set, crank, pistons, rods, cam, lifters, intake, bearings, balancer, water pump, all the bolts, all the gaskets and all the machine work for $915? BS

    Not defending him, but the rod, crank and pistons and usually part of the short block. I still don't see the #s adding up though. I don't see the mark up that high on speed parts. At cost , maybe 40% savings.
