All mopar big blocks had a forged crank through '68 (I think), but the earlier big blocks had a 3" thrust bearing, compared to the later cast cranks that had a 3.25" thrust bearing. Someone please correct me if i'm wrong
Go with the 413. Take the huge savings and get a crossram and original valvecover stickers. It'll have a TON of wow factor for half the hemi cost. I'm building a 392 & 9K doesn't seem outrageous with injection included. As an otherwise chevy guy, it appears early hemis are in fact made of gold.
DRD57, the templates were sold by mopar. I don't know if there still available or not. The 413 industrial and motorhome engines have heads that have water passages over the exhaust ports. The pickup and passenger car engines don't. On heavy duty applications this keeps from destroying valve cover gaskets. My personal choice is the 413. I've had both and for the daily driving, the 413 will be hard to beat. Cheap factory electronic ignition, modern valves and seats, selection of goodies. Looks good to me.
None taken. cuz you're right. I guess my statement was based more on economics. I'm sure your car is gonna be bad ass, and a breath of fresh air, but 9 grand is a lot of money for just the motor. BTW, is the Hemi blown and injected? Tell us more.
Motor is injected, Your comment probably should have been taken the way you meant it, but it is unbelievable the amount of people say why bother it's a Plymouth Etc.. You are right about the economics of it probably smarter to go with the 413.
I think it boils down to what you want out of the car. A 392 Hemi can be made to run well, and look cool, it's got more "curb appeal". The 413s can be made to run hard, and would probably need some aftermarket goodies to make it interesting and different enough to stand out near as much as a 392 Hemi. I love 1937 Plymouths BTW. I find it bizarre anybody would say anything but BUILD IT!!!!! Great lines. The MoPar class A motorhomes with the INDUSTRIAL 413 did indeed have raised waterpumps and different heads. These industrial engines have little in common with a passenger car 413 from the deck surface up. I say build the 392 Hemi, but beware the space it's going in, the engine will have to sit back a fair ways to get it between the fenders I bet......
