Fock.........On my back all day, pulling the tranny back to get to the flexplate bolts on my truck......one mother*&ker is rounded off....only have about 3" to get a 12 point wrench on.......Looks like going to have to get a cutoff wheel in there.....Pain in the azz.......you think it'll back out after cutting head off? I hope there is enough meat to grab it with vise grips or with whatever......

After you cut the head off & get the flywheel out of the way, put a nut on it and zap it in the middle of the nut with a mig welder, the get on the nut with a wrench & back it out. Don't forget to unplug ALL electronics, ECU and all before welding on the vehicle.

It will probably spin out by hand unless its rusted. If you do cut the head off, you still have the thickness of the trans case left of the bolt to grab with vise grips.


If you can find a Sears store with this set in stock, and you can get in there, consider the bolt as good as out.


They have the same thing in end wrenches. If there is any flat left on the bolt, these will grab it.

If you have an air chisel and a long, flat blade bit, you can rattle the bolt head on the side in a counter clock wise direction. This will usually bust it loose and once it moves a little bit you can probably unscrew it by hand.

Before I started cutting I would try one of these spline wrenches, they work good.

Well......got it off .....I went to sears and bought a few things.....one item was the wrench set gn7 posted.....nice set....it'll replace a set I got from my dad...hand me down stuff...I was in denial...dads gone....and the tools were heavily used....I was too stubborn to replace them. They mean a lot to me....I got a real good bite on that rounded nut with the new set.....it ate the rest of the head off....I then pulled out the other tool purchased....it's a kit of 6-8 heavy grade low profile bolt extractors.....pounded it on to the head of the bad bolt....15/16 wrench on it.....busted it loose. New flexplate installed.....new bolts!!!! Installed new starter (summit brand), I bought new flexplate and starter......now dealing with starter crap.....it won't engage into the plate.....roll crank....it might.....next time it won't ......took off for the third time....put it on the bench....it chatters at times when I test it.....should of bought the better starter.....cheap focking shit....now I'm dealing with it....came in for a drink....go back out there tomorrow .....

Congrats on the fix.
I may have to look into a set of those wrenches and those extractors.
I have a lot of EZ outs and have seen the type like you show, but never thought of buying any...
until now.
Thanks

I had my doubts.....wrenches will get used.....extractors not so sure....at 25 bucks.....worth it. Saved me from having to use a cut off wheel.....on my back....in my face...with tranny pulled back 4"....

well, after messing with the POS Summit Mini starter.....bought a Hitachi mini and all is well.....I also changed out the 750 DP Holley for a 650 DP.... Holley also.....was chasing a bog all last Summer....with the 750....throttle response now seems instant.....no test ride yet......I also now notice......at idle, carb is whistling....I've heard in the past.....that, that could be a indication of a " under sized carb " for the application ?????? 355 sbc, small hyd roller....zz4 basically with a cam up grade...510 - 525 @ 108 CL

Listening through a short piece of hose while probing the other end around the carb can sometimes help identify it's source and location. My bet is it's a small vacuum leak between the manifold and the carb. Could be coming from somewhere else, but in my experience another re-torque after removing, inspecting, and re-cleaning surfaces can fix it and sometimes a new gasket takes care of it. Others may have had different experience, it's not something I've had an issue with recently.

Thanks....can't hurt to look in that area.....the whistle tho is more (to me) like the carb is sucking at a high rate...I can hear it in the driver seat while tipping in the gas .....maybe the new carb is more efficient and that bog is history....hope to drive it soon.....still lots of snow here and cold....going to 48 today tho!!!!!!

Both conditions Jocko.... On and off....high pitch whistle....I'm thinking the 650 maybe a tad small....I'll drive it soon.....maybe try and make a pull and read the plugs. I just want drive ability ...the 750 would chase me out of the garage in a matter of mins.....and the bog was pissin me off....seems to be burning better with the 650.....

Forgot to mention....Summit Starter I bought fits both BBC and SBC....9 teeth.....it was a 50-50 chance it would line up and engage flexplate.....B&M 153 tooth.....the Hitachi .....10 teeth....engages every time .......that one extra tooth made the difference ......just thought I'd throw that out there......Dewey

48°... A good sign it's about time to dust off the board shorts and run an iron over the Hawaiian shirts :))THumbsUp

The whistle is not, in any way, a sign that the carb is too small. It's simply manifold vacuum pulling air through a small vacuum leak. It's either creating Helmholtz resonance like a flute or something is vibrating like a reed in a clarinet or saxophone.

To help identify the source, you can even spray short blasts of carb cleaner around the base of the carb, down the throttle bores, and on any vacuum line connections while it's running. When it stops momentarily, you found it's location.
