Ultimately its YOUR engine. Im just trying to save you some heartburn and disappointment. Even Doug told you over 9 to 1 on an Aluminum block is bad. This doesnt even take into account the fact that Doug has seen hundreds of these and put at least 15 of them together as warmed up street engines. Most of these ended up torn down for various problems.
Also to consider is the amount of work and dollars you will have to put in just to see if it will work.
Dont forget about the corrosion problems with this engine as well.
Im not trying to get you to not build this just dont over do it. There are a lot of ways to make a slant not be a slug and a 9 to 1 engine can be fun to drive.

I know bro, The idea was to bleed just a lil off with some overlap in the cam.
I want 145psi dynamic with which ever cam I end up using, thats for sure.
it could end up 8.8 comp and I'd be happy.
You know if I was to do a roller in this it might even break the lifter bores off with the spring pressure, who knows...
I might just build a boring stock motor out of it that sits in the corner of the shop most of it's life meanwhile build a stout iron block .060 over, long rods, same bolt on's but bigger cam with 10.2 compression...
All I know is there is some good reading over there with dougs builds, some of it quite entertaining and reminds me of a lot of engineers I run into that think cause they are engineers they know all...thats when they wash out the rings 'cause they think they understand carbs' ..thats also when they toss rods like doug did trying to run .004 rod side clearances and such...no no
Not bashing doug but to do all that and then roll the dice on tight clearances doesn't make sense??
I would think one would just face the rods a lil and polish the thrust bearing down, been there that.
I liked the light rotating mass idea a lot though[for an aluminum block]
I won't run under .006 crank end play, and I like to run .002+ bearing clearances as well.
chrysler had the oil holes on the rods for a reason.
I also wanna get more info on the block filling of the deck and if that would work like doug says instead of having to weld or whatever.
I can't post pics on slant6org, so I might not get any notice over there.
I'm used to 'high volume' sites, thats why I'm here at FABO!
once I talk to keith at autopower and we go over our options, I'll be able to make up my mind.
