They make good power, but at a higher rpm than a big block, and at more expense. Plan on a stroker, or cutting back the impeller. If you will be satisfied with whatever performance you end up with, then OK. If you aren't, thats when the big expense comes in: LSX block, heads, stroker, intake manifold, etc. We have been involved in the engine builds on several of these so far, and have built quite a few for cars too. We did one of the first driveline/flywheel adaptor from billet stock before they were available. Remember the carb/ ign deal from e-brucks, not cheap, the oil pan mods to fit the boat(we did those),or the guy in Michigan who will redo your computer if you go that way, to remove the smog, powertrain, and antitheft functions, also not cheap, or aftermarket computer. Our major user is on his THIRD motor, each bigger than the last. Second intake/ throttle body, fuel rail setup(we did those too), third set of injectors(each set bigger whenever he ups the HP), custom fuel tank with pump and return(did that too). Unless you have a low mileage Camaro/Vette motor sitting around that makes decent HP out of the box and you are willing to chop the impeller, or again you'll be happy with whatever you come up with just because its different(truck motor?), make a thorough list of what you are getting into. The ancillary components will absolutly cost more than the longblock. Call for further questions. TIMINATOR 623-877-8553
