a 4.3 is a stout fuckin' engine.. anyone who says different should shut the hell up :rofl:

... serously though

4.3 crates with mod's can garner about 285hp.. or more.. and blow that 120mph top end away..

mine still has its governor.. which cuts off at 93mph.. lol .. i need to fix that.. and redo the dash .. cause I need some romp room ..I can get it up to peg'd extremely fast.. and wished I could go faster..

thanks for the link to the rear end ratios.. I learned mine has 3:73 ratio... which is kinda nice.. I keep learning shit about mine..
