Well what is better-Ls1 to ls6 stroked and carbed or LT1 to LT4 stroked and carbed. Is the LT1 block better vs the aluminum block?

It's not so much the block as it is the heads that are better, just look at the flow numbers of LS heads and you'll see where the power is. If you want an iron block go with a 6.0L LQ4 from a truck and slap a set of GM L92 truck heads on it, 330cfm flow for under $1000 :)

Heres the twin setup i run on my 88 gta. No times yet but this spring should be interesting. As it sits now, rolling on to the throttle the car boils the tires at 140km. Should be good for 9s if i can get the power down.
