Thanks for the input !!!!

I was simply pointing out that my top radiator/grille brace does double duty. Stock '33/34's had the cowl brace pair that went from the top of the radiator back to the top of cowl, but I'm using a pair of billet aluminum units that I attached to the top outside of the radiator, running back to the outside of the cowl. The hood top has bars that mount four pins that latch the hood top down to the mounting bars. Scroll down to the "Hood Top Only Latch Kit" - single opening hood latch kit Triple opening hood hinge/latch kit hood brace kit No bearing on your '40 installation, but they do sell some other nifty stuff.

Roger and Jerry, Thanks for the feed back.

If you mount a radiator from the 4 corners( two botton/two top) instaed of the factory used tri point mounting, you will eventually have a failure from frame twisting as the tri point system does put the radiator in a bind like the 4 points---sorta like the 4 link rears vs the 3 link system--

That's why it's critical to use the spring loaded bottom bolts, so that the flex of the frame compresses the springs as opposed to torquing the radiator. At least on mine, the top braces also provide enough flex that I'm not concerned with twisting the radiator tank. Of course I may be wrong, but I'm not worrying about it.

I worry about everything ! Some times I just have to get over it. I went to install my donor flexplate on my engine 2 day and as usual with my free parts it was wrong, too big. So here's the question. I have 2 choices for a new flexplate, standard for $30. or Heavy Duty for $90. It seems like it'd be a big pain to have to pull the motor for a bad plate in a few years. I guess what I'm asking have you guys had any troubles with the standard plates ? Thanks

Why is it too big???? There were some different diameters /number of teeth---but all it took was using the correct starter location-----

I have a 168 tooth plate which is way to big in dia.. I need to use a 153 tooth. The block only has one set of holes that I see, I'll take another look.

Navy,
The starters are what's different, one for the 153 tooth flexplate and a different bolt spacing for the 168 tooth. Both flexplates will have the same crank bolt pattern.

Like the other have mentioned the I’m not sure what you mean by being too big…….The flex plate won’t fit in the bellhousing or the starter interferes.

To expand a bit on what Roger posted.

If it’s the case of the starter interfering, there are different starters used for the 168 and 153 tooth flex plates. The one for the 168 tooth flex plate uses a starter that has the mounting bolts staggered, and the starter for the 153 tooth flex plate has starter bolts located straight across from each other.

Just a bit of FYI…..the 1958-1962 283 blocks came with a 168 tooth flywheel (the flex plate you currently have) and the block is drilled for the staggered bolt starter. They do not have the second bolt hole drilled for the 153 tooth straight bolt starter. The second bolt hole can be drilled and tapped in the block if you need it however.

As far as needing the HD flex plate, I would say probably not as long as the one you have is in good condition. My experience is that flex plates normally go bad in the teeth area due to improperly adjusted starters. I have replaced a few over the years that were cracked out in the center area where they bolt to the crank flange, but that is fairly rare. With a 283 I wouldn’t worry too much about ripping the center out.

Thanks for the inputs guys ! Here's what I did. I put a new flywheel on the motor to match the starter I had, it was cost effective. The block does have 3 holes for starter mounting . The way I see it the starter should be able to turn over a 283 even with the smaller flywheel.
Here's today question, its about venting the crank case.
I have the vent cap that is bolted to the back top side of the block, {see pic with no cap installed}. I have a vent cap in each valve cover.
Do I need to keep the block vent or can I block it off with some nice turned aluminum plug . ?? OR should I run the hose that originally came off the block vent to the carb where a PVC valve would hook up ? And what about a PCV valve ?
Here's some pic's.

If you're using this on the street primarily, then I'd vote yes to the PCV Valve on one side and a Breather Cap in the opposite valve cover, then plug the intake with a welch cap. I like breathing clean air thank you very much! LOL..

If you're heading for the track primarily, then use the vented intake as well as vent the valve covers. And yes, you've labeled the hose connections right on the Holley. There should be 1 more under the front bowl also. Is yours plugged?

Maybe this'll help too?

You will definitely want to run a PVC valve. There are a couple of options, but if it were me I would do as 34_40 suggests and run the valve in one valve cover and the a breather cap on the other, then tap a freeze plug in the vent hole.

If you elect to run the PVC valve from the vent hole in the block you need to verify that the vapor separator (the round can looking thing in the lifter valley) is in place or you will suck oil into the intake. Normally you only need to run the PVC valve in the back of the block if you are running the early non-vented valve covers and have the fill tube/breather on the intake..

Positive Crankcase Vent
Poly Vinyl Cloride


And the vent on the side of the metering plate is used on Ford applications----the GM type use the bottom one


why are you running coolant hoses off the back of the manifold??

I knew that....my fat fingers didn't
