Are the pre LS engines becoming a thing of the past? - Lateral-g Forums

I think it is slowly going to go the way of the ford flat head. People are still totally into the flat head, but just slower nestalgia type guys.

For sale: 400 ci SBC, bowtie block, crower shaft rockers, the works. Also, shelf full of hot SBC parts, ported heads, cams, rockers, pistons, headers, carb's, and much more. Owner giving up on SBC's and going full bore into LS.

Seriously though, I am not sure I will build another car that will use the older technology. I'm building a pretty neat "budget" LS motor for the 70 Camaro right now, and if it all turns out like I expect it to, and I have every belief that it will, it'll be bye-bye time for all of the older stuff.

(p.s. New motor is LS2 sleeved block, L92 heads, LS7 crank/dry sump setup, L76 or possibly sheet metal intake, modest cam. Confident that it will be an easy 600+ crank HP motor, current estimates for all-in costs, less than $8k, brand new)

what are the main reasons an older motor cant be as reliable as a new motor?

I just picked up an 18 dgree busch motor......790hp on pump gas. Rpm range is a lil up there but still awesome power with only 9.1 comp. I will agree and say most seem to be going with the LSx in different variations of size and power adders. I heard rumor nascar was testing LSx stuff not sure if it is true or not.....

I'll say it again, the gen 1 sbc is going the way of the flat head and will be looked at in a similar way soon. There will always be enthusiasts into them though.
The sealing methods, crossbolted mains, light weight and superior head flow of the LS are just too great to overcome. The ports in the SB2's in Nascar look more like an LS7 than a Gen 1.
Also price out a EFI'd gen 1 compared to an LS, you'll be suprised.

I heard there are Regional divisions of Nascar looking at carb'd crate LS2's as a spec motor.

There's not doubt that the future is LSx, but the Gen 1/2 motors as well as BBC's will never go away.

I heard that about nascar as well. I don't think SBC or BBC will ever go away either. But LSX's are becoming more and more popular

Which we like

LS for me. I can't believe the heads for these motors and how great the mileage per hp is.

Well,

Have you guy's read the April CarCraft? They bought a 6.0L truck engine (Iron) for like 1100$ added a carb set up (for simplicity they say, even tough i don't seet the point) but only added a cam and headers and spitted out 480 ponies!

They say next month is well over 500 with nearly a few bucks in it!

Hard to argue with that no?

I sold my LS1 combo just a while ago because i was feeling it was already dated (also because i made a smokin deal) as we all now see LS2's popping everywhere! It didn't even make it to the frame!

I'm waiting for someone to crash a Trailblazer SS to pick on it.

Starting with 400 Horses should be nice.

I have a guy i'm talking with who has 2 400 blocks for sale cheap too, 'wsa thinking 434 SB...YouthPastor, if you find those pills, LET ME KNOW!!!
