XXO/BVGC '38 Chevy Coupe Build

Rich, I'm trying to find something like what your talking about, but no luck so far.

Trent, I'm talking about using something like that. One fender, though, won't cover the tire sufficiently- it will take two grafted together.

That was just the first one I found in a search. there are several variations and the glass types like Rich posted. Shop around, price and quality vary.

Also a search for wheel spats got some interesting hits

It may not seem like it, but there is still lots going on with the build.

Pinkees is building the side panels.

Russ Meeks has the pistons, wrist pins, and valves, for coating. He also has the front plate, and top girdle, for Cermachrome.

Dale is polishing the head chambers, so that we can send them to Russ.

I've been trying to figure out some wheel cover/fenders, and an axle spat, for aero.

I've also been talking to Dema Elgin, about a roller cam. The older Harley solid rollers will work for us. This pic is a Sportster lifter I'm using for mockup. If we end up needing it to be a little longer, the pan/shovel lifter will work, and has the same diameter-.730

I had a lifter block, that had been repaired, so I sacrificed it for a mockup part. I didn't have anything in a .732 diameter, like I wanted, so I drilled it out with a .750 drill bit, and notched it with a chop saw. Rough and crude, but it will work for now.

We will need a 'plate', along the bottom of the lifter block, that will be notched, to act as lifter 'guides'. I notched this one, top make it easy to get in and out, and to use for a 'baseline'. I'll send it to Dale, and he can install it with the racing cam, and get final measurements. It won't be exact, as a new cam must still come from Dema, but it will work!

I'll take the final measurements, and the good lifter blocks, and get them altered to suit our needs.

Woody is going to do some flow simulations for us, so I messed around trying to get the ports molded tonight.

The intake came out good, but I'll need to do the exhaust again- this foam stuff is a PITA!

These are from the #8 cylinder- you can see how flow restricted it is at the valve guide. Dale will do the race engine, and all the molds will then go to Woody.

Nice thing about a flathead is that you don't have the side loads on the valves that a rocker brings to the table.

I suspect that if you hog it out and go with some bullet nosed bronze guides, and straighten the ports out as best you can, you should be golden.

I've seen foam port molds like this, but I never knew what you use to make 'em with.

What is that stuff?

[38flattie]

Chris, it's called FlexFoam-it X, by Smooth on. It's a pliable, 10lb foam.

My long term plan to 'straighten' out the ports, is in post #706, page 48- I'm simply going to have the 90 deg turn milled off of the block,port the bejeebers out of it, and weld a new intake/exhaust flange back in place.

Buddy, I am glad you don't have a week heart.    I cant wait to see it run!  Tony

Looking at post#706, I would have said that you've removed 45` of the original 135`, leaving a nominal 90` port runner. What am I missing?

[38flattie]

Haha! Tony, I'm just not smart enough to quit flogging this worthless pony!

I should just get busy with the Jimmy, and make some real horsepower.

 ...I keep looking at those IH Black Diamond engines- they have some serious promise- ever really looked at one?

Nothing Jack- you're correct. I won't be able to totally straighten out the ports with milling- it will take some porting, epoxy, and even then, it won't be perfect.

I do expect a dramatic flow difference, though. Only one way to find out......

If we were smart we would find another drug that has a cure.  There is no cure for salt fever. Tony

I have looked at Red Diamonds. I wonder about the new rule concerning "Engines that ran at El Mirage" Is this a ploy to out maneuver the 'Binder?

[38flattie]

Finished the exhaust mold today,( black is intake, white is exhaust),and mailed them off to Woody. I'm very curious to see what his model tell us.

Dale did extensive port work in the constricted area, and that port work, along with the huffer, is what we are banking on!

 I also went to Pinkees, to check on the panels Erik is making. They will be done tomorrow or the next day! We had to give up a little aero, to be able to mount fenders, if we wish. I'm thrilled with how they turned out!

Gotta go pack for work now!

Looking good my friend!
