Mopar Performance Crank Spacer Pulley

This is what I have in a 9.5-1 493 6-71. Not running yet. Low boost, street car.

Looks like .500 intake .550 exhaust

I know of a 3.75 stroke 413 with 4.233- notched bores, 270 TrickFlows, 725 HP

Nice work, Im guessing its all getting surfaced and girdle installed when your done with caps ? Is SDC and BCR one in the same ?

Is that 10-1 499/ 452’s a pump gas engine ?

That part number is from RPM International. Says 4340 Nitride 6 bolt. I could not find anymore info on it

BewyWell-Known Member I built a 523 stroker in 1980, waaaaaaaaaaaay before any of the stroker kits were available. I used a 440 crank welded up for a 4.375" stroke. ..... I used off the shelf 460 Ford pistons. Had the pin holes enlarged to take the 440 pins. Used 440 rods. I see you are...

Ding ding ding we have a winner !!! Thanks WildRT Hopefully I don’t waste $650 on Ford pistons I can’t use.

I don’t think custom have been $1000 for a while, $13-1400

Absolutely, just hoping that maybe someone on here has BBM and BBF experience and might know if the pistons/ valve pockets are similar enough to squeeze in ??? Or if needed enlarge the pockets a little to work ???

.990 works and they offer a few different pin heights and flat, dish or dome. BBC is canted valve. The ford FE is a wedge.

Why bbc or why try and fit a different make piston ?

So if you’re building a 4.25 bore 413/426 it seems there are not many choices except custom piston$. Icon and others have pistons for BBF that might work and was wondering if anyone has tried or is familiar with fords. Is there any way to figure out valve layout and compare without buying...

Can’t go wrong with the stealths for $1200 440 Source Stealth Cylinder Heads

CNC-Motorsports | Performance Auto Parts and Engines I use this to find stuff

Saw this on FB

Billet Aluminum Alternator Brackets - Doty Manufacturing Inc. I have a red one on the shelf from years ago....... it will end up on one of my projects

Yup, well my best guess is either something is together wrong, balancer is off, keys ways are in the wrong spot, and it really is higher than 30 just not showing it, or it needs better than 91 octane and more timing. But I’m on my second shift OT with only 5hrs between them and 2 of the 5 was...

You ever brake rev a car to set timing ? Brake rev it to 2500-3000 rpm, Turn/advance Distrib until it starts pinging and back it off till it stops. Lock distrib down and check timing. See if it’s at 30*

I didn’t either but I read something about them a few days before I came across this and figured I’d should post it.

No problem, I was impressed, real nice build

505-CID Mopar 440 Stroker - Hot Rod Engine Tech

I hope your feeling better and doing ok. I have icon 4.382 bore pistons with 16.4 dish that look the same as what’s in your motor, 440 source just advertises as 17cc but it’s an Icon 16.4cc piston. Besides, they use the same photo for all the dish pistons on the 440source site. That spinning...
