Poll: What would you rather see R&D on?

[CaptCobrajet]

Brent, if you bore the cam tunnel in a topoiler style block, you should look at making the oil groove deeper.  I usually make them 427 size and depth when we bore the tunnel because you have to fix the groove anyway.  Some 390 blocks have a very shallow groove even before boring the tunnel.  There are 60mm babbit bearings for the 2.500 bore.

I turned one of those "dueling 390" hydraulic rollers 7500 on hydraulic rollers just to see if it would go there.  Peak power was at 7000, but it did not float at 7500.  Ford non-adjustable, conical spring, 11/32 valves.  240/248 at .050........it is doable.

Will do.

Running 7mm and 5/16" stem valves here. 

It may just work.....

Hydraulic lifters are for girls.

I vote the flat tappet for only one simple reason. Class rules, some groups do not allow a roller cam unless factory equipped.

In the near future I hope to start assembly on just such an engine for a pulling truck. Blair has a set of heads with my name on them for just such an application. But granted I am the minority.

You sold all your shit, so go to the back of the line, pussy.

[FElony]

Grassroots?  Can you explain?

Every time I have brought up something along the lines of DIY grassroots, you have shot it down. Not wasting my time again.

[Nightmist66]

I vote for the solid flat tappet.  A 12:1 high rpm 390 just screams old school.

If you can wait just a lil longer..........

In another post or two Felony will be telling you to run flat solids on one side the block and rollers on the other side of the same block.

Cool! I can't wait to hear about it.

I mean, we all love seeing engines that show big on the dyno and never see the insides of an engine bay, right? I mean, nobody actually drives an FE hither and thither, right? Daily? Oh, drat and pshaw.

I don’t own a vehicle without an fe. So yes, daily driven.
Let’s see yours. Otherwise get to the back of the line felony.

Vote for high rolling hydro roller. Bring it on. JB

While it is true that I sold my Thunderbird & Mustang, I am actively building a 427 stroker (with a solid flat tappet cam) for my '65 Cyclone. That fact was included in the post where I revealed that I did sell those 2 cars.

Never let a snarky reply get in the way of the facts.

Pussy, indeed.

That alone is pretty cool, Drew. I've got 5 licensed and insured vehicles that I alone drive, 3 of which are FE powered, and I'm about to add a 4th to that FE list. One of those 6 is about to get parked permanently, and it ain't one of the FE ones, so yes, driven ALMOST daily.

You should post about that, Tommy. I'd love to hear more about it.

[FElony]

So much more fun being a bad guy instead of a good guy.

On a serious note, I like Barry Ratrodnick's second paragraph in post #18.

Doug,
