yeah! its damn impressive, but at 403 cubic inches on that ls engine, running on 22-30 lbs of inter-cooled turbo boost pressure,and I'm assuming E85, I can,t help but wonder if your not going to be able to duplicate or exceed that power output with something like a 477 cubic inch big block with a 3.75" stroke and 4.5" bore.

on the 7 second pass it says they were running C16 so with that leveling the playing field in detonation resistance anythings possible... but even with the 8.3x at 160 on the 93 pump swill yea i suppose more displacement you may go faster except that LS cylinder head design is so vastly superior to any of the factory or off the shelf aftermarket big block stuff that im not sure if the results can be duplicated with the pump gas. i mean the trick flow 255 head flows In 363cfm and ex 262cfm @600" and 382 / 258 @700" right out of the box with no porting or any work.... and if we are talking about single digit race cars theres this for the ls series...

so i mean if we go to big blocks i think it would make more sense to pop something 500+ inches in there to compensate for the other effects that running a bigger heavier motor brings about. you also have to consider packaging... the aftermarket makes dropping a high performance LS into any common vehicle platform easy and cheap

the problem with building a big block chevy based engine is simply that you need a bottomless checking account balance because theres dozens of company's with hundreds of products that can be purchased to build just about any conceivable combo if you have the bank balance to pay for the parts, and even cylinder heads that easily bolt on stock blocks can be purchased that will flow in excess of 500cfm on the intake ports if you have the cash.
the LS has a rather large aftermarket support base as well and theres some impressive heads available, but due to the basic block dimensions and stroke and bores size limits your never going to compete in total displacement with some of the aftermarket BBC offerings, but then again COST is a huge factor and EITHER engine design could easily cost you upwards of $15K to build a fairly robust example.

heres a 770 hp 454 cid LS based crate engine that costs $24K

heres a 720hp, 572 cid big block crate engine for $14K

DO YOU REMEMBER READING THESE ARTICLE'S?
salvage yard turbo LS builds are some thing that you might choose to look up and explore, keep in mind its NOT ABOUT PEAK POWER, but the POWER TO WEIGHT RATIO!
the HELLCAT weights about 4200lbs and with 707 flywheel hp thats about 6 lbs per hp, a 2900 lb z car would require about 500 hp to easily out accelerate the hellcat if properly set up

i dont know if anything is actually BETTER than anything else, sbc/sbf/bbc/bbf/mopar hemi i think there are steps you can take with each motor design to make a real fun car that competitive at any level of street or race performance. shit, a 302 powered fox body with 350tq to the tire naturally aspirated and a 4.10 gear is a FUN STREET CAR and you go can go out and have a blast with a whole build costing you less than 5 grand depending on what caliber of car you started out buying. on the other hand i know guys who have three times that amount of money in their mustang, have beautiful cars with superlative paint and interior that makes you feel like you should take your shoes off to get inside, but they are slow moving as pond water. it all depends what your goals are and your budget is.

this guy obviously spent some money on his combination and right now the aftermarket is saturated with LS everything so thats what he went with... but there are plenty of BBC "phony pony" builds from years past that are fast as all hell too...

with regards to the crate motors you have to think that people look at a 120" smaller motor, with a shorter deck, with the aftermarket suport to bolt into anything, thats lighter, that makes 50 more hp... i mean i wouldnt buy a complete crate motor like that, probably ever, partially because i think alot of the parts on crate motors would need to be swapped out with ones i think are more reliable or make more power, and partly because i'll probably never have 25k to drop on anything, ever at one time like that.
