Re: Starting a new project, 89 Mustang "back in the day" street / track day car
I was looking for the .080 (i) to .100 (e) typical for a 6000 redline with stock rods, so I put the both a 40p and an e7 on my E6 lower end without a head gasket to get an idea since I'm wanting to use a ~.550 / 224* or so cam (whatever a XE274 comp is). Wham - even with the stock cam. I figured it should clear since the gasket is maybe .041-.045 ... this is a real zero deck block though, so I guess that would be close to .015 or so with an uncut deck (depending on stackup , I know, but most of them I've looked at are about around .015 or so in the hole stock.
Isky had a tool they would rent for modding the reliefs, but I'm bad about returning rental tools so I thought maybe I'd have a go at making a tool for it.
I've always had a bit of visual issue with how the closing event impacts this. I tend to worry more about the later closing event on the intake than the lift, but since I was goofing around with spares anyway, I went ahead with rolling it over. The head wasn't super tight so it would have lifted it before breaking anything. I watched the lifter plunger compress maybe .010 or so before it finished. It may just be my junk - the E7's have never been decked to my knowlege - it was completely stock when I pulled it down years ago. I can't speak to the 40p's.
Unless my math is screwed (and it's possilbe, I get ate up by dumbass every now and then) the intake would be at best .030 with a felpro gasket, maybe .045 or so with an uncut deck. It's just a bit tighter than I'm comfortable with.
