Dad spent a very long career playing with his flowbench and heads and intake and exhaust system until he got very high numbers at low lifts. And it paid off with a highly responsive engine that flys from idle to 5800 and revs like a small Chevrolet with an aluminum flywheel. And it idles...

Three words I learned from watching and driving Dad's heavy wagon. "Low lift Flow".

I always ran a gasket on the head side. Doing it this way you could reuse them and they stayed in good shape.

Ok, if anyone wants to see what a $7 heat shield looks like, here it is. I bought three of them long ago (McCord) and the boxes had shields for both sides. I'd be glad to give this one up to VANS and will contact them to see if they are interested in seeing/borrowing it. It does not have the...

So, I suspect all of us with "current" subscriptions pretty much lost the investment we made in them, right?

You could make an epoxy die and go to town getting rich! I still have a used one that could make the sample.

I did the same kind of work on my 69 340 Dart long ago. Hack saw and few wrenches and they fit great. In the trash can.

Here is an expensive but cool way to get silence and loudness! When closed and quiet: no resonation, no roar, no noise that bothers you inside. When open: they roar and resonate and cackle and snarl and are pretty obnoxious like most chambered mufflers are. 10 dBA difference across the...

Sound like the old Purple Shaft HEMI grind we put in then took out after finding out how poorly and sluggish it drove in our conditions. P3690213 was it?

Those are 409 stainless and for sure, 304 stainless would be tougher but significantly more expensive if they are still American made.

With those being straight header mufflers (they look like anyway), wonder if the pulses out and back in are hard on them? They have no support inside so if the engine's exhaust is pounding hard, the negative can happen too? They are not very thick wall but man, I am not sure.

There is no sound control in some aftermarket mufflers like the original mufflers will give and without resonators, it could be a beast with that big engine. The muffler volume is needed to get the sound levels down and who knows what the non OEM mufflers are like inside. Resonators were an...

Cal, I looked at your Jensen factory style exhaust and it looks like you have zero room to play under it. I'd be sure it has the OEM mufflers (2" in and out I think??) and the factory resonators at the end and not just empty cans. I am sure there are some round mufflers that might fit (like...

Guessing it may be a 5.0 from BM???

See if you can find a Dr. Gas X-type Crossover around there. I know he sold some overseas. They will smooth the exhaust tone but not sure the owner will be able to tell inside as much. Maybe I missed it but what mufflers do they use?
