    Hey, I was wondering if anyone would have the slightest idea of where I could find a GM ramjet 502 engine. And how much it would cost. /forums/images/graemlins/1zhelp.gif

    You could do better building one yourself IMO. For that kind of money, you could have the 427 ZL1(?) all aluminum block ($5k) and all the rest of the components for less than $4K, for certain.

    Not saying thats a better way to go, just showing how expensive the Ramjet is. The injection system on it is a joke compared to true EFI IMO. It was made for boats.

    The "updated" 427 block looks pretty good. Dunno about longevity...they DID come in factory available cars (in small quantities) so it must have been something GM figured would last for at least a year or two! I actually would like to have one, although they should have set it up for roller lifters and one piece rear mains for that kind of money.

    My point though, is that with the Ramjet cost, you could probably build a really wild 454+, and still come in WAY under what that thing costs. It probably has good components (forged crank, good rods, 4 bolt mains, good heads) and although I've never really sat down and figured the cost of everything, short of an all out race motor, I think you'd be hard pressed to spent over $8000 on even a strong big block. Just look around and see what the components for a BBC cost you, even from GM, and compare that to the Ramjet.

    With the 4L80E (transmission) "standalone" controller costing somewhere over $500, you know that you are paying at least that for the Ramjet "controller", probably $15-2000 more for the intake, injectors, and so on over a non-Ramjet engine.

    I bet there are other companies out there building 502's with great components, do some searching if that kind of price tag didn't scare you off in the first place. /forums/images/graemlins/smile.gif

    How much do the 427's cost, and where would be a good place to buy one, or what kind of vehicles had them /forums/images/graemlins/confused.gif

    The 427 block alone was $5K last time I looked. (www.sdpc2000.com has them if you check their engine blocks)

    Not sure if anyone is using those as a base for an engine package or not.

    I seem to recall something like 66 Corvettes getting the ZL1 block originally. Others made it into other cars, but the Corvette I *think* was the only one that came out of the factory, intended for public use, that way. You aren't going to find one of those things in the local classifieds. /forums/images/graemlins/smile.gif (a side note, apparently more ZL1 Corvettes exist now than were actually made lol)

    I really don't know my big block stuff that well, but the bore of the 427 is shared with the 454, so I guess you could just slap 454 stuff in a 427 block and it *is* a 454, if you are looking for that kind of engine size.

    In GM's engine lineup, I doubt you'll see more "hop up" parts for any other one than the 454, except the Chev 350.

    Both of those engines seemed to be the "best" of the big block and small block engine families, besides the fact that they were the two most common engines used in Chevy's. (454 being most common big block, 350 being most common small block)

    You are thinking of the 302 for racing purposes.

    ZL1 from all accounts I can find, was a dealer ordered/created Camaro (no need to get technical on whether the factory made them or modified them, they exist, thats what we are talking about) and only 69 were produced.

    The Merlin 540 CID motor is like $8k. I'd say that's a better buy than the 502, if we're talking pull it out of the box and bolt it in and go.

    The ZL1 427 was a '69 only offering with 69 Camaro's & 2 Vettes being offered.

    The Yenko Camaro's were Iron 427's

    The New Aluminum ZL1 (454ci) is a modernized offering with roller cam, but using factory ZL1 tooling. They only plan to make 200, so I'm not sure you can get one anyway.

    As for building one yourself, it is cheaper until you pay for the fuel injection manifold, computer & injectors..... this will likely be $3000 or more unless you are using a Holley ProJection TBI or equiv. Don't expect the same low end torque with a TBI unit or a carb.
