Re: 354 stroker

Yes, the counterweights have already been trimmed, but it will need to be balanced. Hopefully that won't prove to be too difficult.

Re: 354 stroker

I just picked up a 392 crank that has been machined down to 354 mains and BBC rods with 4.05" stroke for a 331 or 354. I want to get pistons for this, but where do people recommend that I go? I don't want to have to reinvent the wheel here so I would like a piston manufacturer who has worked with th...

Re: Stroker 392 Crankshafts

But most, if not all of the people "back in the day" that were using stroker cranks didn't bother with running water in their motors so they could cut up the water jackets without concern. My question is what is the largest stroke that a stock motor with uncut water jackets can take? Did the 5/8" st...

Re: Chevy Distributior?

I sell a conversion to use the GM HEI module on the stock '70s mopar electronic distributor. That is what I use on all of mine. You can check it out at: www.designed2drive.com
For a stock look, I would use the Pertronix II in a stock 392 distributor.

Re: does early chrysler poly/hemi intakes interchange, if not, t

Yes, they all interchange hemi-poly from 1955-1958. Even the 392 will interchange with the 331. 1954 and earlier will not interchange with the newer ones due to the water jackets being in the intake, but you can still use them if they cover the water openings and you route the water to the radiator ...

I suspect that a compatible coil just refers to the correct primary resistance. The pertronix modules require at least 2 ohms primary resistance. If you don't have it in your coil, you can use an external ballast resistor to make up the difference.

It is centered on the crank. It is used to center the manual transmission shaft with a bronze pilot bushing installed. How accurate is it centered? Accurate enough since all 392 cranks (to my knowledge) are actually drilled for the bushing. Accuracy would only be an issue on much later cranks where ...

I don't know about the drive gear value, but I do know that you cannot use the marine motor in a car directly without a rebuild. First, the crankshaft has no provision to mount the timing gear. You need to pull out the crank and have a shop weld the mount on, or put in a car crankshaft (usually chea...

I agree. I believe it is wider and the exhaust exits at a lower angle than the 426. I used one of those brake linkage arms or scissors from a later A-body on my 68 Barracuda.

Correct color for 1956 New Yorker 354 Hemi?

You are correct. Stock color is (argent?) silver for the whole motor except breather, spark plug wire covers, and air cleaner; which were black. Chrysler 300s had gold valve covers and gold air cleaners. Everything else the same color as the other models.

Stay to the 4", but remember, if you plan to use std bore 392 pistons you will loose about 1. of compression due to a smaller dome volume. I have heard that before, but I don't understand it. Doesn't the 392 have a larger combustion chamber? Thus, going with the smaller head should give higher comp...

Good question. I was disappointed to find out that I couldn't use the stock water cross-over with the new aluminum heads. I would even be satisfied if someone cast a decent cross-over for use when putting 354 heads on a 392 that would work on the aluminum heads as well. PAW are you listening?
