LS2 vs. LQ4

I agree with you VFF JEFF thank you for puting perspective on this and adding an opinion that is not only true but does not try to directly down someone elses opinion like a few others have tried to do!!

What gets me is guys that have to come online and insult people by telling others they are smarter than everyone else. We had one here not long ago that bragged about knowing more than anyone else, even the guys in the LSx business. Nobody knows everything and anyone who thinks they do is more dangerous than a newbie that admits he knows nothing. :twocents:

im:newbie: but I ask questions if i dont know. I dont just pretend to know, and be pompus like some users If seen before. bottom line? iron or aluminium, just pic one, either way you will make plenty of power, and have your fare share of problems.

last word huh?

does it matter if i hate everyone baecause they are faster than me??? and know more than i do....

This has gone past entertaining it is hilarious, and Stupid. When I see comments that I think are absolutely stupid I try to ignore them. Like the DEI idiot. No comments necessary. What can you say that everyone else can't plainly see.
I vote the moderators delete all the nonsense to get this post to where it was started.


Too much :bsflag:

I thought it was a good question.

cost for sure i just did a Lq4 swap the l2 was almost 8000 more

*Chuckles* I know I shouldn't but I cant help myself..........speaking as a machinist and general smart arse the reason all Fuel class engines are all based on alum like T-6 and others instead of "good ole iron" is tensile to weight ratios while you could obviously engineer an iron block as strong or stronger then the current alum why in the hell would you? Alum blocks can and do make over 4k hp and are dead reliable at 60% less weight the failures sighted in alum Lsx's as far as I can tell have mostly been design/build failures not material failures hence the changes the CR5 team made along the way, to their blocks.anyway from a material view of course alloy iron has higher tensile properties then say t-6, however the tensile stress/es encountered in even a maximum effort road race engine are well with in range of duty for modern alum mixes, obviously for the success/es in all form of motorsports using various high output alum black based engines

As for the original topic question..........i dunno......
