Yeah im going to stay NA. Say when this motor goes and i go to say a 383 stroker or 402 can i reuse the 5.3 heads or then would i need to go with ls6's?
243's are proven and give you room to grow. Not to mention you can mill them to 59cc for more compression or do like I'm doing and run a .040 Cometic gasket to bump compression slightly.
The drag race guys with LS1s love the 5.3s. But they are not getting any more real power then they already have.
PP 243s with light wt sodium filled valves and great springs( I have comp 981) there are better springs now, 224/224 518/581 112 plus other things, and have great power, just over 400 to the ground
YES the smaller runner will provided higher air velocity which should mean more torque with the right cam. But for the same price? 243s
I'm calling ECS monday too see how he feels about the subject from the input i got over at ls1tech I was just about set on 5.3's. Now im going to ask chris and think about it some more
