440” small block, pump gas, street car...

Cam is a bit rowdy, but FUN to drive around town.

440" SBM sounds good....tell us the details!

Never in my 40+ years of running Mopars have I ever heard of a SB 440... Guess I learn something every day

Indy Cylinder Heads have been making them for years.

It’s been a possible combo for a long time needing a big bore. 4.17 stroke X 4.100 bore is an example, (4.220+ bore size able race block needed here ->) 4.2 bore X 4.0 stroke is a 443. 4.07 X 4.25 stroke crank no longer available IIRC = 442 cubes.

IF you have the big bore small block, the one that is able to be bored to 4.2, then use the 4.25 stroke crank, you’ll end up with an incredible 471 cubic inches.

The current problem to achieving this (IIRC) is now the crank as the block can be a Ritter block for the bore size. Then to properly feed this size engine, you have a cylinder head problem. It only gets so good.

Hughes still sells Kits with 4.180" stroke length. Did Rod Bloomer stop selling the mopar rotating assemblies?

[dusterdoug]

Yep, big inch small blocks have been around awhile now. Mine is as follows...

R3 block
Rod Bloomer stroker kit
10.6:1
Indy 360-1 heads
T & D rockers

Holy Batman......now i understand what you mean regarding the cam.....some pics from the engine assembly? Did you dyno this beast?

Michael

 

[crazydog]

No one remembers the Mopar crate engine?

Mopar Crate Engine Performance Motors - Small-Block Monsters From Mopar (motortrend.com)

Too bad the bastards don't sell them anymore.

 

[Mstall]

Are your indy 360-1 heads there cnc version?

Yes, it needs a smaller cam, will do that someday along with EFI...

No engine assembly pics unfortunately. My dyno will be some 1/8 mile timeslips this fall!

Yes sir.

From the last (final) DC/MP catalog. Remember those?

So it's a solid 14's car?

Looks real good in the pic.

With my luck, probably!
Thanks, it’s an amateur built low (relative) dollar garage car. Huge thank you to FABO member (and 25 year friend) ‘63GT and Ken DeSimas for their help in any way that I needed!

 

[360duster]

Cool, i like it. Have fun with it!

Michael

 

[justinp61]

Very nice build.

 

[B3422w5]

Sweet, I like it.
Cam is very big for that compression, and being on a 112 will need a ton of convertor to get it to leave well.
But, super sweet, looks like lots of fun!

 

[rumblefish360]

With a cam like that, I don’t think he cares about a the few thousand lower rpm’s. LMAO!

 

[justinp61]

I wouldn't doubt that it's pretty stout down low, that 4.25" crank is going to help. His cam's duration is bigger than mine, 263/271 @.050, 108, .711/.719" and I'm running 11.2-1 compression. My 434 is a monster everywhere.

I'd be willing to bet he could run almost, or maybe 1 more point of compression and be okay on pump gas.

An acquaintance of mine had a 471 (edit, small block 471)in a nine second street 71 demon, made a couple of Mopar magazine covers.
Also built a 501 (or was it 502?) Small block. That one was a little too far over the top, didn't last long.
He's now on his 2nd or 3rd demon challenger, not counting a couple hellcats.....
