Way more info than I asked.. didn't read your whole post to be honest.. I know about all the turbo possibilities.. it's just not what I wanted or asked.. AND you're talking about the 190cc 11Rs heads, anyway, with a 56cc chamber. I asked about 170cc 11r heads, with 53cc chamber. That's kinda funny since you're being a smartass. Really can't find hardly any info with them on a stock short block and what the compression would be( I've seen the 170s having p2v issues but not the 11rs, even at 53cc).. There would be no conversation on here if the same question couldn't be asked more than once. Find a new forum or new hobby if seeing the same question more than once hurts your butt. Turbo is about the only way a 302 can survive over 500hp and if I wanted that much that's def be the most economical way to get there. Anyway no hard feelings. It's of no consequence now, as I decided a 53 cc chamber would result in more compression than I would want(thinking over11:1). Wouldn't want more than 10:1 tops. I already ordered the afr's last night. Btw my stock heads are toast.. and at that point you might as well get a set of cheap($8-900) aluminum heads rather than spending money to refresh stock heads for weight saving alone imo. And at that point why not spend 600 more and get some really good heads that actually flow.
Oh and I would be blown away if a spooled 28spline 8.8 broke a shaft on a 330hp street mustang.. the differential is the weak link. But you knew that
Damn....
I see now that the 170 version of the head has a different chamber...I also see that just like the bigger volume head, the 170 comes in two different size chambers......a 53, and a 63.
So I was quoting a different head, I used the very first result that came up from the Google search. All irrelevant info since you've chosen some other AFR head regardless.
( Despite the fact that you couldn't be bothered to read my whole reply,..you partly heeded my advice anyway,....so good on you)
You obviously like throwing money away, and I gotta admit, I'm probably the cheapest assed guy here, so I'm conflicted over giving you advice that you can't be bothered to even read completely. Makes me wonder if I'm wasting my time with you.
Nahhh........I just love giving advice. The fact that you won't follow any of it don't matter one damn bit.
You know what says " I don't know what I'm talking about" about some of the stuff you're saying?
You don't know how to google.
But since I'm such a nice guy,.....here, let me do that for you.
For all those people who find it more convenient to bother you with their question rather than to Google it for themselves.

If you rebuilt your engine, you should know all of the variables it asks for. You should know what your piston volume is, you should know what your deck height is, what your bore and stroke are, what your gasket bore diameter is, and now you know.....what your chamber volume is...so see....I helped you again.
You can tell people stuff and the really, really dumb ones will just put their heads down and jump right off a cliff anyway.
Now, far be it for me to insult anybody's intelligence that are "just tryin to learn" .....but there are those chosen few that still insist on doing dumb sht.
If you don't think a stock 28 spline axle won't possibly snap off once you put a set of sticky tires on, rev the engine to 5000 rpm and side step your clutch at the starting line at the drag strip,...you better spend some time at the drag strip.
I'm not saying it automatically will, just as soon as you put A,B, and C together... But it could, it has, and like I said...sooner or later...it will.
The fact that your stated plan was to not build a drag car, but still insist on putting in a spool in a street car is tantamount to watching children play in the street....
Even the most callous of people would yell at the kids to GET THE HELL OFF THE STREET, BEFORE YOU GET RAN THE HELL OVER!!!!
Despite the fact that most here would consider me an opinionated prick,... I'm not totally insensitive.
So.........
DONT PUT A SPOOL IN A STREET CAR, BEFORE YOU LOSE CONTROL, AND RUN THE HELL OVER THE KIDS PLAYING IN THEIR YARDS!!!
*And as an afterthought...I just gotta ask,...once you go ahead and put that full spool in place of the "weak differential"....
How do you intend to keep a stock c clip axle in place?
