A lot closer how?its a hell of a lot closer to drop in then what you posted up !
you ever see some of the tolerances on the China junk ... nope bet you never even put a Buick motor together yet .. let me know when you've put 200 motors together with your own hands
A lot closer how?
Because he’s got the balancer and flexplate?
Or you saying the stock used crank he will most likely get need absolutely nothing checked or redone?
Come on come on... tell me, come on Haha
Since you done so many engines you should know that Modifying the flexplate and balancer for internal balance is not to expensive.
Right??
Now your just making wild assumptions.
You do things your way..
I’ll do things my way..
And the OP will do things his way
yeah drill more holes in the stock flexplate .. its not like there 30 years old and are prone to cracking from the get go ..
so put in that new crank .. blow more money into machine work to get it to work .. then swiss cheese the stock flex to work ... load it up on boost and see what it does.. BRILLIANT !
I felt it was a suggestion fit for a person like you.
Since you want the op to cheap out and get a used stock crank.
I figured you like it.
Anyway this is getting no where with you.
You not answering questions.
You’re just pissing around the bush.
Probably because you realized its not that much of a price difference.
Sense you want to cheap out on the crank.
Next thing you’ll be reusing old gaskets to save a dollar.
Your just stuck in your old ways
I’m done with you.
Nothing more to say
I wasn’t even the one that suggested the after market crank to the OP.I doubt he is building a powerhouse .. he has a stock crank already ...
even if the crank needs a .010 / .010 he is in it for peanuts and good to 500 hp all day ..
just cant understand why point him to $1000 bucks into a crank when I doubt he is building over 500 hp ..
guess in the end your right .. if he wants to blow a grand on a crank he doesn't need .. its upto him
You will always get someone telling you to convert to IC set-up, without understanding your goals.
My understanding is that you are building a hybrid to cruise, and want something different. You have already put in a lot of custom work and you are happy with the set-up. The engine is damaged but you are well on your way to you overall goal.
Yes, the 84-85 crank will fit in a 109 block, and vice versa.
No, the HA block is not “weaker” than a 109.
Yes, some have successfully used NA cranks for low/mild HP set-ups.
Yes, a forged crank is obviously stronger but there is additional work/cost because they are internally balanced.

Turbo cranks and 4.1 cranks have rolled fillets on the rods and mains and are the stronger cranks. Yes you can use the 84-85 crank in the 86-87 109 block.I was wondering if a 84-85
Hot air turbo engine crank work in a
86-87 109 block

With this kind of help and support, maybe we can convince this guy to sell off all those other toys and go what most of us idiots are doing. Go full blown Turbo Buick junkie!I have a 86/87 109 Crank and rods that I might be willing to give you. The crank is standard never turned. It would need checked for straightness as it came out of a high hp block that actually cracked in the lifter valley.
The Scat china crank is a nicely finished crank and of 4340 material, but it lacks in counterweight weight. One of a few problems with this it will need $200+ in heavy metal on top of the balance cost. I have been in discussions with them to rectify the issues since June of '17. Nothing yet.
No it is not Balanced.So a brand new "internally balanced" Scat crank isn't actually balanced?
And needs new balancer and flexplate? Well that sucks....
I would have to disagree about the HA block being as strong as the 109 . All you have to do is look at the valley of each of them . Please explain how you feel the HA block is just as strong as the 109 .
I’m well aware of the common weak spots as I’ve had my share of broken block . They all have cracked the mains . Now as far as the lifter valley area there is more material there in the 109 blocks unlike the hot air blocks . There is also more meat around the the oil pan with more bolts . Now you tell me why would they just switch to a 20 bolt oil pan for last years of production? Did they just want to make new oil pans ?
