2019 Engine Masters Challenge rules posted.

I already sent an email with four questions. We'll see what they come back with.  The worst case scenario for me is a 64 model 352.  4.06 x 3.797.  I like the G head better than the R head on the 410s and later 390s.  I could reuse the crank in a 390 Super Stocker if I had to.  Fingers crossed on the HR, and somewhat crossed for a 428 CJ.  The 410 wouldn't be bad, or a 428 passenger car for that matter, but I think those size engines run out of cylinder head versus the BBC.  I asked them to consider letting any engines 375 cube or less run under the small block RPM rules......

[Barry_R]

I probably asked the same questions

[Royce]

You guys are ahead of me..
I did asked how they determine what is a small block and what is a big block. The true big blocks in my view are the B and RB Mopar, BBC and 385.  My knowledge on Buicks and Olds is imperfect so not sure where they shake out, and of course Pontiac and FE are really Medium blocks.. 375 Cubic inches would keep the true big blocks out of the picture and let the mediums play both sides of the fence..   Probably too much to hope for.. 

What is the potential of a 396 vs an FE. Would a W engine have a play?

[Barry_R]

I asked the big block vs small block question too.

Starting to lean toward the .060 over 410 combination.  Gives me a 4.110 bore and maybe a stroke change to 4.090 crank cut for 6.8 BBC rod journals.  Gets us to 434 cubes using readily available parts and hits the compression target with minimal head cutting and a flat top piston.  Could build this one cheap & fast other than the heads.  The 352 would still be better if they let it rip as a small block....

Y'all need one of my enclosed cam tunnels for factory blocks!

[TomP]

The headers have to be minimum 3 1/2" collector... so much for the 289-302 idea.

There are not huge selections of FE headers like that but there are some.
 I assume High Performance or limited production would not allow any High Risers but might not let Cobra Jets too. Or square port BB Chev?

Looking at other classes at least they allow lifter bores to be sleeved on Coyotes! LOL

02   -   ENGINE   BLOCK
Domestic   OEM   production   Coyote   engine   block.   Engine   block   must   retain   OEM   cylinder   bore   
spacing   and   OEM   block   angle.   Lifter   bores    may   be bushed.

Maybe...

You can adapt for the header collector - they just want a common hookup at the end for dyno installation

[FrozenMerc]

Maybe Hemi Joel with a straight eight 420 Duesenburg. Stroked & bored, sheet metal intake, two fours, zoomies...

Since we are just bench racing here, let's run this thought out.

Model J - Naturally aspirated - DOHC, 420 ci, 3.74" Bore, 4.76" Stroke, 5.7:1 compression - stock - 265 Hp @ 4250 RPM - That is a bit better then 1972 454 ratings......

Assuming one could afford to play with one of these motors (they make SOHC's look cheap), could it be competitive???  All practicality aside....

First order of business: Bump the compression up to a realistic number, probably custom pistons, something to work with the hemispherical combustion chambers.  Bore to help unshroud the valves...

Custom Cams to help it breath.

Will the bottom end and rotating assembly hold up at 6300 rpm???  With that stroke, piston speeds are going to be in Pro Stock territory - Custom Rods required???  Bearings???  Torque would be diesel like with that long of an arm.

Can the intake and head be modified enough - with in the rules - to achieve acceptable flow???  The siamese intake ports aren't going to help here. 

Werby - Is the Gonkulator up for such a task???



 

[shady]

Maybe de-stroke it & declare it a small block. Impractical build? sure. Impossible? probably.  Cool factor? Coolest of the cool. For sure would get the cover of HR. You would have to get Leno involved for the deep pockets. Anyway, it just me being a wise ass and thinking outside the box as usual and not at all being serious.

[Barry_R]

You would need to have a couple guys in black suits, white shirts, skinny ties, and tommy guns as a security detail.

[Royce]

Let's ask Joel... He has one...Maybe he would sacrifice it on the altar of torque and horsepower....

[Joe-JDC]

Probably have issues fitting the SF Dyno bell housing they use at JE.  LOL  We had to remove the ring gear just to get our engines to fit their dyno.  Joe-JDC

Has anyone had an answer back from the questions@enginemasters.com ?  I haven't as yet.  Would you post your question with answer if it does not give away what you are planning?  Joe-JDC

Just as a public service FYI - from comments I've seen from Drag Week participants trying to get rules answers from anyone at Hot Rod, or their parent company The Enthusiast Network, it can be a long wait sometimes to get an email response. I think a lot of those people are scattered around the country at various events, and not always paying attention to emails, or at a desk. It just seems to be hit or miss whether you catch their attention. Again, just a FYI if it doesn't seem like you're getting a timely response, you may have to keep working at it.
