Quote: Hey STREETWIZE! You are right!!! I'am a true diehard mopar guy, but in the last 10+ years worked on the LS MOTORS!! Have you look at the LS-7 head? I have one hear in garage! On a 4.125 bore @.400 lift it flows 303cfm!!!!!! Find another head to match that!!! Someone needs to make one fit the, "LA" block!!! Would need to be biger port foe the big block!! I still the more development needs to be done for a "B" engine block!!!! Combinatoin's A good aftermarket black, without side rails, more like a big block chevy!! And put a real oil pan on it, and it will make more power!!! Why due you think that Richard Maskins is making a block for the 'LS" without side rails!!!
5.7 eagle on a 4 inch bore goes 275 Cfm. Don't know about the 6.1 or Apache but I think they would be right with the LS7.
