    Thoughts and opinions on used Pistons and all connecting rods

    Been plugging away on my car recently and I am now charged up to start on my engine. The budget is starting to squeak! So I am considering looking for forged .30 over 340 pistons. Then for connecting rods, my 1st machine shop didn't want to work with my stock rods, wouldn't even look at them...

    A little help here? Smallblock build

    In need of some tech help outside of my circle of knowledge. First allow me to preface this question with 2 criteria... I do not want to throw good money after bad. Meaning I need to try and use parts I already have as opposed to just buying something else. Second, I do not want to leave easily...

    Opinions wanted on a 340 build

    Finally brought my 340 home after a year. It is a 71, 915 heads. Well it is froze up, so clearly my dream of a hone, bearings,cam and gaskets is no longer viable! The 915 heads are most likely 1.88 valves. My thought it to put a light piston in it and rather than spending the money on 40 year...

    340 recommended intake

    I have a stock 71 340, planning on 3 season daily driver use weather permitting. Going into a 71 Duster, 833od, 3:55 rear. Comp XE268 stick, and the stock TQ. I have a Performer intake. Will this intake be holding this engine back? Also considering a Torker II. Open to other suggestions so long...

    Do I need a road racing oil pan?

    Bout sums it up. Street car, spirited back roads, heavy braking, on and off ramps, occasional auto cross. Do I really need that Milidon oil pan or am I just trying to make myself spend money, that might be better used somewhere else?

    In need of an education..340 vs 360.

    Hey guys, I've been a 360 man since I had my 1st one built back in high school. I have spent the last 20 plus years absorbing everything I can about hot rodding 360's. I had settled on a .30 over flattopped, eq headed, magnum rockered, performer intake and Tq carb. The cam was still up in the...

    Which smallblock or combo?

    Over the course of a few years I have accumulated a pair of 360's, a set of late magnum heads, and then just recently a complete 340. Now I have been in love with the idea of a mag/la combo, and have been a 360 man my whole life. So what donI do? Do a mag headed 340? Mag headed360? Leave the...

    it'll get away from you, if you let it!

    It is amazing how fast an engine can spiral down into the abyss of high dollar, bragging rights, etc etc. I just tore down my "26k" rv motor yesterday, it gave me no signs to make me think it was anything but a low mile engine! No cylinder ridges, bearings all pretty, journals all clean and...

    What are the practical limits to the stock Magnum Rocker package?

    Hey guys gonna start building my engine soon. I know the stock La rockers are pretty good, they may not be accurate enough for some of the hardcore, but they can be plenty stout and reliable! Had them in a 360 years ago with a .509 lift cam and spun it to 6000 rpm all the time, with no problems...

    Homemade EFI, what manifold?

    Hey guys not gonna start building yet, but I wanna start looking. If you were gonna do a homemade direct port injection EFI, what manifold would be best? Then to throw another wrench in it, need to be able to keep a/c, and fit under a stock Duster hood! Thanks, Dan:burnout:

    Can a cast crank survive in front of a 4 speed?

    That pretty much sums it up. Will my stock 360 crank survive in a street car with a 4 gear! Seems all the muscle era cranks were forged in front of 4 speeds! I'm just gonna make some noise, rev it to around 5500, bang some downshifts, and beat up some curvy roads. Thanks Dan

    Any spreadbore carbs for Magnum heads?

    Hey everyone, in my years of aquiring parts I picked up a real affinity for Thermoquad carbs. I have 2 la blocks, and a set of magnum heads off of a 5.9. I also have a Performer intake. I havent mag'd the heads yet, so they may or may not be good. I would prefer to use what I have....I am not...

    360 options for mileage and performance

    Hello everybody, just found my way over here from Moparts. I've got a pro touring Duster in the works right now. I want max mileage and respectable power. I keep kicking around injection, like a Magnum motor or even a Hemi. I already have a very low mileage, excellent rv core circa 79. The...
