Kind of nails it with that statement.

Bring it on budro... I've got 489 cubic inches of pissed off aluminum big bock with your name on it baby!

I tossed around the idea of building some sort of stroker LS motor for my 69. It all boiled down to conversion costs for me. I like things done right and all the other crap I would need to switch over including tuning was blowing my budget. So a 496 with AFR heads and a either a hydraulic or solid roller it is. I can reuse just about everything off my last BBC and have more hp/tq than I will know what to do with. If I want to drive a LS I can get in my DD.

I have both -- and have built with both -- old skool and LS... I'll take the LSx any day.

But then --- there's no substitute for cubic inches... OH WAIT -- you can do that with LS too!

Price out a all aluminum old school 427 SBC or BBC with EFI and dry sump.
Then compare to a new LS7 small block.

Price out a 383 sbc with heads that flow 315 cfm and EFI
Then compare a LS3,

BTW
I've got numerous 730 hp LS7's out there that run on 92 octane, even passed emissions in the UK. They get 20 mpg with a 6 speed.

Hey guys,I am starting to feel like the guy in the 3 duece flathead rod when a fuelly 57 chevy pulls up.......!LOL

I hope you are aware that the LS7 disighn is a steal from GM between a mopar botom end end a ford top end engine disign.

And that that engine in modern corvettes. are alouwd to use 1 to 1 1/2 quart of oil every1500/2000 miles.

And that fuel injections only hase 2 benifits.nr one is that is gives MPG at 50/60 mph and afther that it uses just as mutchs fuel at trotle as a regualr old school V8 engine. nr 2 you dont need to tune your ignition/carb twice a year.

Did you know that the LS7 engine in race corvettes only last 35 hours. then need a compleet rebuild ,due to a engine disight fauld where the piston squirts are to short!!!!..

Im a oil sponser in a international super car race class in Europe
LS 7 corvettes, Moslers V8 stars against ferarris / lamborginies/ aston Martin /
marcos / BMW / Mercs. ecetera.
The LS engine hase superior acseleration for sure top speed is great to say the least.
durabilety is mutch less and maintinese is mutch higher then there euro counter parts.

Also the rediculess price tag on hp parts for the LS engine and the corvette that GM and there vendors in the afthermarket artifisialy keeps high to push the corvette into the same leque as ferrari ecetera is rediculess to say the least.

buy a stok LS7 with 500 hp then try to buy a 700 hp LS 7 engine from a reputable engine builder like Kteck ecetera and your paying a exstra 10 to 15000 usd!!!. what is wrong here.........

If we build a 700 hp aluminum traditional ponticac engine mill with the same 4 inch stroke it wil beat up on the LS 7 engine torque wize plus durabilety it wil rev just as high and fuel consumtion will be the same.
same thing with a SBC ore BBC for that matter.

also for the record the GM LS7 hase NOTHING to do with a traditional chevy engine disighn its a CORPERATED engine build. ITS NOT A CHEVY..

I will say that my big block makes effortless power and I feel with injection it would be a strong contender for drivability. The carb does let me get away with murder on the race track and tuning. It eats up my .666 lift cam a 252/260 @ .050 pretty well where it will idle smooth at 1000 and cruise as low as 1600 in 5th. Lot's of average power. I have to admit when I start it cold I would love for it to sit an idle without touching the gas.

( Driveability ) Bingo, jump in start and go. Because of this I drive my 69 alot more than I drove my 67. Now if I get another musclecar, it will be old school fun.

This may all be true, now take a stock old school and a stock LS engine, bang for buck, superior fuel control = longer life. I was not talking about professional racing, who can afford that?

Oh and GM stealing from Ford or Chrysler does not bother me. I love my L92 and could care less if it was built by a terrorist. ( well maybe I would not admit who built it if that was the case )
