Are the pre LS engines becoming a thing of the past?

[jeff s]

Back in 2002 when I built my Ultima GTR, I wanted EFI. It was more money for me to EFI and build and aluminum head Gen1 SBC that to get a complete aluminum LS1/LS6, with a cam change and cnc'd heads I had 500hp.
I bought 2 LS1 long blocks for $800 ea, I had a 5.3 iron block with alum heads given to me, the garage that installed a new engine into a Tahoe found none of the core people would give them anything for it. I bored that one to 5.7 and it'll end up with turbo's on it soon.
A LS2 aluminum block is $995. I've got twin turbos on mine.
Flat heads haven't gone any where, there's still people into em, and lots of new parts available for em as well.
When was the last gen 1 or 2 put in a production car? 10 years ago

HP is good but what about Torque numbers for NA
they seem alot lower compared to Hp numbers on LSx motors??
Some wise ppl told me Torque is King on the street:

I am done with hauling cast iron on my cars for ever. I love the LSx quality and leak proof components , and best of all light weight! Thanks GM,please bring the bluedevil engine asap on market

There's more to it than making power.. which engine would get better mileage?

A big in big block better make more than 700hp. depends on what is it in and what kind of race it is.

I had them factor in the cost of the aluminum block, the roller camshaft plus the guideplates, pushrods and lifters you would need for it, fuel injection, serpentine drive and all the other accessories (alternator, steering pump, starter, waterpump). That's where the cost got inflated. Yes, you could probably do a 480 horse small block for a lot less than that but it would be just the long block in cast iron configuration, flat tappet camshaft, and standard carb/intake induction.

I wasn't aware that included assc. Still seems up there but with a/m injection and wiring etc. I could see where it might make it that high.

Actually in all fairness, what should probably be added to the cost of the LSX engine is the sum of all parts and services needed to actually get the thing in your car and running. It looks a little something like this......

1.) Rework wiring harness/reprogram PCM......$300
2.) Modify oil pan......................................$235
3.) Modify stock fuel tank...........................$625
4.) Adapter plates and crossmember.............$350
5.) New Driveshaft....................................$350
6.) Headers (Hooker).................................$625
7.) Chassis Dyno Tune...............................$500

That's the big ticket stuff, there's more but it's mostly nickle and dime stuff.

HP will never go out of style..
