Thanks, good pictures. There really is a difference! My thoughts: Good thing is possibility to get a bit more compression and real tight valve to head clearence. A good way to build high compression flathead. result is good for low-end torque. Downsides are plug hanging out middle of...

Correct. The way to get faster burning velocity is for example methanol. Spark plug placement has nothing to do with this.

Okay, sparkplug in transfer area. I have a very hard time to see this resulting performance/ torque gains. this is something I'd like to see test data or numbers? Flame front travels faster, how? Do you use less advance? quench is another story, lets focus sparkplug location. I have never...

Chart has a typo about 41T head volume. I've measured those, came out around 82cc if my memory is correct. Chamber shape is worth noticing though. It's much deeper at transfer area than any other Ford head but shorter towards piston. that is, similar to famous 81AS but real deep. If someone...

Very good, I agree!

German blocks also have those holes.

Neat documents, thanks for posting these!

38 coupe, Very good! this will be interesting. I see my block is allready posted:) I'll email you.

Thank you all, That's very nice ad! It's said to be from 1953, earliest I've seen. I agree, original Fentons are the way to go.

Thanks for update, you were lucky to find those merc parts! Yes, your 8BA oil pump will fit to merc pick-up tube assy. It is nice fit with that correct oil pan. These together are the best possible windage tray solution for flathead V8. Just check pick-up tube isn't bent and your good to go.

Do you guys know when Fenton headers for flatheads first appeared? I think early fifties? Did a search HAMB, but didn't find this. Thanks!

Interesting. I think it is Ford Pilot engine, those had similar plugs rear of the block?

Okay, so this is internet forum? I get that after reading this. Op question was answered at posts 6 and 7. Then I see only few posters in this thread actually understand how oil filter works, I'm talking about so called full flow, modern times engine pressurised filters widely used since...

Ken, that is good example about reproduction oil pump pickup. It is useless and very dangerous. I do believe them all are like this? Any braking, cornering, acceleration and there is a change oil pump will get air. I would't want start engine with something like this inside. Use original. if...

That's a good question. maybe if wide 5 five drums are 2-piece where drum is joined to hub with studs. was it -39 drums like that? Something like this could be possible solution. machine centre out, bore holes for wide five, swage it all together with studs...

38 coupe, good idea to machine heads. I have used this technic many times when building Harley flathead strokers. easier with flat top pistons ofcource. Sonic test is the way to go. and do a test for cracks also. I do not believe comp pressure will destroy iron heads, that's likely because...

There was 29A heads, probably Mercury ? pre -42 ?

Thanks, now I know what to look for. seems very expensive.... might have to fabricate this one.

Just found another photo, this is from ebay. seems it is part of pickup tube assy? is this mercury part?

I use bolt cutters as well. Fast and simple way. yes, dangerous flying valve pieces!
