Easiest Big Power, LS1, LS2, or LS6?

[nitrorocket]

Iron block has not proven to be any stronger, unless you are after well over 1000 hp, I would'nt take the extra weight. People have made over 1500 hp and gone 175 mph in the quarter on the aluminum block. I am at 1000 hp right now myself.

Patriot heads are factory heads. they are ported factory heads. TEA are the way to go here.

For low dollar, a 427" motor requires a new crank. Not cost effective. An aluminum block ls1 will be a 347, an ls2 block can go a little bigger on the cubes due to having a 1/10" bigger bore (3.898 vs. 4.00)

75's will be perfect and are the largest high imp injector made right now.
