4.500 bore was considered best as tested on a 572.

Some of you may have seen this already. I just saw it. Thought I'd post it for those who haven't.

I had a shortblock assembled at Hughes Engines about 20 years ago. I supplied the block, crank and rods. They did their race prep machine work and supplied the remaining parts. The bill, $3800

I've seen, read where some Poly, LA 318's can go to 4.00" bore size and still have adequate cylinder wall thickness. There's a racer, maybe here on this forum with a grey 67-69 Cuda with a 318 block that, according to him, went 4.00". No, I haven't personally done it but I'd check the block...

I run an air gap on my small block '71 Duster with a 1" spacer, average 2" air filter/cleaner & it clears the stock hood.

What's the weight difference?

4.18 Molnar crank, RaceTech pistons, 12.9 CR, .036 quench, OOTB Trick Flows, 1.6 HS rockers, M1 intake port matched, Dougs 1 5/8 headers, Howards solid roller, .640/.645, .259/.267@.050, 106 lobe separation, 950 AED carb, 112 octane fuel, 20W20 VR1 oil, MSD dist., 36* timing.

225cc Eddy Victor heads, Super Victor intake, 1050, appropriate roller cam if I had the coin to spend. The short block you laid out is exactly what I plan for my 414. Good luck!

Although my car is a Duster I have an air gap intake, originally holley dp, but FiTech efi now, at least a 1" spacer with factory '69 air cleaner and it all clears the factory hood. Hope this helps.

I guess I had a brain fart. The more I rack my brain around it, a 4.00" stroke is easier. The Molnar cranks I've looked at though, the price is the same so I figured why not go bigger.

That's what I was thinking too.

I have a standard size set of bushed connecting rods with 2.125 small end diameter. I'm considering a forged 4.125 stroke crank with 2.00 small end. Can the bushing be removed & "resized" down to 2.00? Or should I just buy chevy rods?

Post a follow up when it's installed. I'm considering that box. I have the Flaming River 16:1 box & it's a ***** to turn at low speeds. I'm getting older and want to enjoy my car.

MRE - Dropped Centerlink - 1973-76 A Body My Earls oil pan is contacting the center link. Thinking about trying this one from Mancini. My car is a '71 but I'm using a '73 K member. Will these work on earlier cars?

On some Mopar race blocks, the distance from the centerline of the crankshaft to the cylinder head deck surface is 9.6 inches and the "short deck" is 9.2 inches. Hope that's clear.
