Engine swap
To answer your question, I do not know of a guide at the moment.
I am planning to send an aluminum 6.0L bare block out to ERL to be converted into a 7.4L short block with longer and stronger sleeves. Precision of Texas Speed has 285 Heads and a short or tall tunnel ram intake. Some hp engine builders are having trouble getting those 2 pieces to psycnh up.
How much power do you want? A little head work and a decent cam will put an LS1 over the 400hp mark.






You'll love the power.
