You would need quite a bit of money to even purchase the LS7 crate motor as well, if I remember correctly. You can get the same power for less by doing something similar to the OP

 

i know the crate motors cost about 17,000. but .....the ls3 in gm performance catalog sells for 15,000. so if you were to buy a crate motor, you could probably sell the ls3 on ebay for some where around 10-12k if it were imediately taken out before driving the car too much. i dont think im going to do it, but i would love to. ill probably just throw a pro charger on.

 

What are your plans for the L99?

 

or you could build a stroker LS3 for $7000 and have way more power than the crate LS3 engine

 

probly keep it around for a while,, not sure

 

The LS376/480 (basically a cammed LS3 with 480hp) crate motor sells for about $7900.

ya and its only 480 hp 376ci and stock heads, my stroker LS3 is 415ci and has cnc ported heads, forged pistons, forged crank, forged h-beam rods and a better cam than the crate engine and will be way more than 480HP and i have $7000 total in it right now and its ready to bolt in!

 

Sorry, I quoted the wrong post. I meant to quote the one that said the LS3 crate motor was 15 grand. It isn't.

 

sorry i was looking at the wrong engine. its about 9k for the ls3.

here was were i found that it cost 17k. it must be a misprint(type) .....http://www.gmperformanceparts.com/se...o_sitelet.html
click on the dale jr camaro and then select the engine and it shows the price.
thats where i saw the 17k price.
thats pretty cool how you can just click on the parts on the car and it shows the price.

 

or for that 7 grand i can put a supercharger on and have about 550+ in less than a days work.

 

yeah, and then you're done. with the 4.0 stroke, he can add a power adder and make a LOT more power. Besides, a supercharged stocker is not as cool as a big bad nasty stroker.

 

gofast908z very nice engine, do you have any numbers , dyno or track??

i thought about going with the 4.1" crank but im probly going to spray this engine so the 4.0" crank was a better choice for this combo.

 

Thanks man.

it did 487/444 through the stall and on a 111 degree day, so you can imagine the power loss with that heat. I've made some changes and it will be back on the dyno for a complete retune, it should do 530+rwhp.

When its time for a rebuild, i'm probably gonna go with a 4.0" crank to take it down to a 418 and slap a Procharger on it with 8-10 psi.

 

not necesarily done. i can still do new heads,cam,intake,throttle body......etc. and the list goes on.
may not be as big and bad but it get the job done. and he said he was only goign to be running about 500+ hp. i can get that from the blower and some(550+) cheaper and easier to install. then do some tunning,power chips, headers, exhaust, lighten the load a little. and still quicker than it takes to build a motor.

 

Did you consider the LSX for a build instead? I believe GMPP is going to have a crate LSX 454 with 660 hp. I know on their site its listed at 620, but I swear I've read 640 and 660 from other GM sources. Anyway, I bet if you wanted to build a killer street engine for drag racing, $18k build-up in a LSX would make an insane engine. I think a power-adder gives something like a 45% boost in power. That would mean a 900+ hp street capable motor. Does that sound about right?
