Hahahhahaha soft. So it is in the tune eh? Unfortunately you have just proven how ignorant you are. Seriously i was really excited you were gone. I love it “start adding power” and how much power we adding? You have nothing to add to any of this. I don’t get scared at blow by, again the ring seal thing you mention is a moot point.
I think we have sufficiently proven that the small block chrysler will easily hold 1k power without any mods. Super high rpm and you will need to do a little bit of oiling mods. Hydraulic roller will need bushed lifter bores to help maintain oil pressure. Thats the point of this thread. All the other bs huffing and puffing is just anecdotal at best. Nobody has shown any evidence to support their claims except the guys making big power reliably. With that said. An N/A small Mopar doesn’t have a lot of head choices to exceed 600hp except pretty much the W series heads 2,5,7,8,9 with 7,8,9 requiring a 48 degree lifter angle anyways so that would require a Ritter or R block (which is discontinued) so that leaves a heavily ported W2/5 or maybe a TF190 or maybe an eddie rpm that has the pushrod pinch removed. So N/A do what you can and dont worry, if your doing a power adder 1k is safe and if its turbo with good fuel injection and a good tuner then 1200 has been proven reliable and I bet 1500 is possible but unfounded. Not everyone has 12k for a short block so the entire package needs to be aligned. And what I mean by that is you pick a target hp or et and build a motor you can afford. A good quality crank and light weight piston and rod package will do wonders for a stock block and if you are going to push it then keep the stroke down which will help the block live. Its a science and thats why some of the ignorant people get pissed at us that do it. We have the experience and the knowledge to pull it off. Yet they continue to talk about their buddies motor or some dude they once talked to or some internet lie.
