Ouch....one would really have to be a hardcore LT1 nut to pay 11K over a 454 LSX block for almost half of that.
I wonder if somebody rigged up an optispark, stock LT1 rotating assembly, put that in the Motown Hybrid LS block with some ported AFR LSX 230 heads is it still an LT1? http://www.hotrod.com/how-to/engine/...own-ls-engine/

I would suppose maybe someone that has a high dollar set of heads, intake, and such already on hand for an lt1 and probably staying with the small block because of the weight break for the dot/street car classes maybe? I know from experience that a person can dump a whole lot of money just into the heads...I already had most of the parts on hand for mine.. if I would have had nothing I would have gone lsx too... so if an aluminum lt1 block was available for 4 grand or less I would probably go for it... but 11 grand for what I do is a bit too steep for me

Is anybody here real good with aluminum welding?
Get yourself an aluminum small block and drill, machine, grind and weld up what's needed to make it reverse cooling and accept the LT1 water pump.
(This is how the Donovan block was made)
If you have a block that'll accommodate the LT1's reverse cooling, you'll have a "LT1" motor.
Use the 24x system, not the Opti Spark system. It'll enhance an LT1, not detract from it. Another plus is you can use a standard SBC timing cover and not do the welding/grinding/milling/drilling/taping for the LT1 cover.
