    I just watched a video of a 2009 ZR1 corvette, that sells for over $100,000, and has 638 hp blower engine. It would be hard and expensive to get anywhere close to that hp in a camaro swap. In the test the corvette ran a 11.20 et for the quarter mile, that's only 2/10 of a second faster than the nearly stock 350 posted on this site.

    You can get that and more out of a LS based motor with the proper forced induction build.
    It's not cheap to build a Gen I 350 up to that HP level either......or a BBC.
    Either way you're going to fork out some dough. So start with the cheapest
    possible base.
    No idea what 350 you're talking about doing an 11.4 ET ??
    IIRC ehe C6 Z06 does 10.99 on drag radials with 133hp less and no supercharger.
    So I'm sure the ZR1 goes alot faster once you put the proper rubber on it
    and maybe a tune.

    LS1's in Fbody's were 13.25 in SLP cars.
    Add a better rear and better tires, and that goes down too.

    If you've never ridden in a newer LS powered car, you need to go drive one
    rather then speculate. It's a world of difference as many have testified.
    Of course a BBC will be alot more fun off the line for sheer grunt power.
    Nothing will EVER touch that. But ......sucking gas like a pig and a boat anchor.

    I have one in my 78 Camaro and I'm probably doing a LS based Gen IV LY6
    in my 442 clone too. After seeing the newer motors......dealing the old
    technology that's not even worth updating , or heads that aren't even worth
    porting and polishing becomes a strong reality.

    Freshly rebuilt 1970 Rocket 350 .......probably yankin it and selling it to a purist.

    Driver and traction are huge factors. You can have a million Hp and if you cant plant it, youre not going to go very fast

    I always wondered why there weren't GenIII style heads/intake setups for GenI blocks, and it seems there were/are. Just only for serious $$$.

    Nice little post there.

    It's cheaper to just pull your Gen I out if you don't have bookoo bucks tied up in it.

    I sat for 3 years doing engine builds on paper.
    355, 383, 400, 454.....turbo's.....superchargers......
    I ended up with an LS1.

    Now with these LS based Gen IV engines soooooo cheap and L92 heads, it's obnoxiously cheaper.

    World Products came out with a Gen I block that accepts LSx heads, but why bother? I haven't worked out the total cost of building an engine setup like that (not even remotely interested), but I'd be VERY surprised if it weren't cheaper to just install a complete LSx engine. Plus, with the LSx block you get a relatively inexpensive aluminum block (compared to a Gen I), and numerous other technological features.

    If a muscle car does an 11 second quarter mile but has a top speed of only 130 mph, it is not just even remotely the same thing as a $100,000 car that does an 11 second 1/4 mile. The $100,000 car will corner and do over 200 mph. You can't measure cars just by quarter mile, that is completely missing the point. I see this all the time online, ooh my $10,000 car is faster (in the 1/4) than a porsche, lambo, etc. Well, maybe, but drive them through some mountain roads and get back to me on what you think. I have driven an LS1 manual trans car and even in stock form they are quite impressive.

    I hear that. I have about a dozen Excel spreadsheets for different engine builds (SBC/BBC, custom built or crate engines). In the end, a Gen IV LSx makes so much more sense for me.
