LS Engine Debate

[XcYZ]

As Chad noted, I don't think there's really that many LS conversions out there. At Car Craft last month, with 5,000+ cars, there were very, very few EFI conversions of any make.

Agreed, I could count them on my fingers.

Hindsight 20/20, I'd do an LSx. For what I've spent on a whopping 475hp in this old Poncho, I should have.

Alot of it is the fear of the unknown. Men are brand shoppers and don't stray too far away from what there used too. We go to the store get it and get out. Until you have tried other options its really hard to have a legitimate opinion, IMO. Conversion to LS isn't cheap either.

I don't hear people putting in LS motors and bitching they should have ran a big block!

For me a gen1 works,Ihave too much time and $$ in it to swap out.However if I were starting from scratch (ie. no motor) I would go for the latest and greatest.I look at changes from the perspective of---What will I get for my dollar spent. Bling--NOT ,Results-GOT

There is no replacement for displacement....

I tend to agree with Todd. However, the LSx stuff now can be punched/stroked to go pretty large. The packaging still is beneficial too. A BBC can be built to shed some pounds with aluminum block too but they are just sooo expensive. Getting tougher and tougher to stay true to the big blocks .

Old school is nice, but letting a computer control combustion, superior ground up design, longevity, MPG's, easy HP, light weight, great throttle response, self protection, ..........

Ive seen two LS powered 69 camaro's that were driven by the owners on the street for a year or so. Both cars ran great with awesome gas milage. They have both since been swaped out for the all aluminum 427ci GM crate motor. The reason I got from both owners was that the LS motors just didnt seem right in the car. They perfer the traditional rumble of the BBC.

...and superior drivability. HP doesn't mean anything to me if it's a pain to maintain and drive.

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..
