LS Engine Debate

[FrankZ]

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.

I pulled a wicked 468 out of my car and went to a built LS last year. It's the best thing I ever did for the car. It's within tenths speed wise and has made the car far more enjoyable and useable.

I'm in my mid fifties and am in the "planning-parts gathering" stages of a fresh motor for my 69 Z/28. As much as I would love to have an injected LS motor in the car,honestly the electronics scare me. Also the expense of having to change everything (mounts,fuel system,front drive,etc) makes the swap less attractive.I can build a decent traditional small block for pretty short money this days and that's appealing to me.

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

I was really trying to instigate a few more responses with my "there's no replacement for displacement". There is no doubt a LSX engine is the cats meow for affordability, economy, leaks, and $ per HP. 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.
