    What would you stick in a project/kit car and why?

    Think of something along the lines of an Ultima GTR. :)

    LT5. 4 valves per cyl means you can get air/fuel in quicker and exhaust out quicker.

    6- more aftermarket support and easier to work on

    LT5 because I like the idea of a DOHC V8 with lots of displacement.

    Not to mention parts availability. ;)

    BUT- wouldn't it be cool to remove the accessory drives and spin that bitch to 9000RPM on a straightaway... :wackit:

    And they both make about the same BHP, right?

    :slap:

    I'd bet valve sizing makes them about equal.

    And personally, I'd rather go with the simpler design- 2 big-ass valves, instead of 4 smaller ones. ;)

    But neither of these motors would work in a beck (although a 3.2RS Porsche motor would be :cool:x10981378).

    And the Cobra guys would scream heresy if you threw a Chevy motor in a Cobra. :o

    LS6, because you could blow up the motor lots of times and rebuild it cheap, unlike the LT5.
     
  12. The fact remains that 4 smaller ones can end up with better top end and less low end loss than a 2 valve/cylinder car, simplicity aside. :o

    Well I'm not saying I know 100%, but I have never seen anyone who felt performance, reliability, etc suffered on a four valve engine versus a two valve. Except you :hs:

    DOHC is more effecient then OHV because of less moving parts. I'll stick with the LT5

    LS6, reliability and availability of parts. Plus, the LS6 is the better motor ;)

    I didn't think they suffered, per se, but I thought that picking the motor simply for the number of valves it has was a pretty silly reason. ;)

    I was hoping for something more concrete. ;)

    Not really- just in that aspect, I'd rather have something simpler. but the LT5 does have it's advantages.

    And they're not THAT hard to get a hold of. GO search on EBay and I bet you'll find 3 or 4 complete motors. It's the parts that are a bitch. :hs:

    With 4 valves you can have vavle overlap. Cann't be done with 2 valves.
