    Understanding External Balance

    Helping my brother with his 360 we are going to be sending to the machine shop. I had my 360 all internal balanced when we stroked it to a 408 and have never messed with external balance. Please correct me on any misconceptions I have. My understanding is that the 360 harmonic balancer is...

    Strip Dominator - Spread bore weld up

    I was interesting in having the spread bore opening converted to a true square bore on my Strip Dominator that is on my trick flow headed 409. I was reading about doing it with epoxy or welding. I don't really think I have the skills for it. Does anyone know if there is a plate that fits...

    SuperStat part No.

    Put a high volume water pump on my 72 Duster and ordered a high flow 180 Superstat to go with it. The one I ordered is way too small but if you search Summit by say 340 it gives this part number. 45358. The intake is a Strip Dominator. Anyone know which one I need? Thanks

    CE 3 way rear drag shocks

    I have searched around trying to figure out the rear 3 way shocks. I seem to find conflicting information. I have the CE front 3 ways set at 90/10 and I understand that to mean that it takes 10 percent force to raise the car vs 90 percent for it to come back down. The rear are 50/50 60/40...

    Port Cross Section and Torque Peak RPM

    I was reading in Andy F's book on stroking the big block mopar about port cross sectional area and that it largely determines where the torque peak will sit. I think its the Mcpherson formula. I was just reading a book Practical Engine Airflow (very good book) and it goes into that as well as...

    Sticky Tires with White Lettering

    I am thinking about getting some sticky tires for the street for my 72 Duster with a 408. It has 255/60/15 all season right now some Kelly Chargers. It looks like the Mickey Thompson ET S/S would be the best option. Going to go for a 275/60/15. However it would be kinda nice to find a soft...

    Trickflow Valve springs & Scrub pattern

    Let me say right off that we should have measured this stuff right off. So.. you can be gentle, live and learn. So in the Racers Forum I posted a thread on 408 Performance evaluation because I felt the MPH in the 1/4 was way off from what I would have expected from this combo. One of the...

    Stroker Performance Review

    72 Plymouth Duster Backspacing

    Before ordering some new mag wheels I did some searching on here and there seemed to be consensus that 4.5 backspacing on a 8 inch wide rim would allow a 275/60/15 to fit on the Duster without issue. Several people posted they did it without problem. I ordered the mags and we put my dads 275...

    69 Roadrunner won't start

    I was wondering if anone might have any ideas to try on this. My dads 69 Roadrunner started smoking at the voltage regulator a couple weeks ago. We put a new voltage regulator in and it smoked again. We installed a new engine wiring harness and my Uncle was looking under the dash didn't...

    408 Stroker. Fresh build

    My dad and brother and I recently finished up building my 408 stroker for my 72 Duster. The camshaft is broken in and timing is set and everything seem to be running great. You certainly can't give it much gas in 1st and then your pealing through second too. I hope we can get to the track this...

    Power Valve Restrictor Channel Tuning

    Good Afternoon. I have a proform race carb and a wideband 02 sensor. I am going to dial in the jetting for lean cruise and WOT. I would like to be able to enrich the power valve circuit more and Proform and other billet metering block style carbs have screw in jets so that you can adjust how...

    Wiper linkage arm

    We had the instrument cluster out to work on a wiring issue and saw the linkage arm was missing. I got one now but it looks like that takes special hold down nuts or whatever they are on each end of it. I am wondering if someone knows where I can get these? Thanks a lot

    Underdash Harness bunt up

    In my 72 Plymouth Duster the underdash harness burnt up pretty good. The ammeter wire basically got several other wires hot and melted several wires. It also melted some wires into the bulkhead connector. A new harness at Classic Industries is like $700. I can not do that. I am wondering...

    Which motor mounts do I need?

    We are getting closer to putting the 408 in the Duster. My cousin mentioned that the 318 motor mounts are different then the 340 and 360. We looked at the two blocks and there is definitely a difference in the width on mounting to the block. I assumed I needed to buy the /6 conversion mount...

    Great writeup on Dynamic Compression

    Good evening everyone. We have started putting together my 408 stroker and the block has nice plugs threaded into the two galley plug holes that go behind the timing chain tensioner. Those holes are covered on the timing chain tensioner. So I am wondering should we take them out of the block...

    Trickflow Powerport 190 heads and TTI Headers

    I called Bob Mazzolini to order 1 7/8 TTI race headers for the 408 we are building. He called TTI to place the order for me and he said that they are concerned from looking at pictures that the header may leak at the bottom on those heads. He said they have not seen one yet in person. I...

    Carb CFM.. Increase?

    I think I know the answer to this but I figured it couldn't hurt to ask. I bought a Proform 650 Race Mechanical secondary carb for a pretty healthy 318 last year. I really loved the carb. The car started right up and ran great with it and was very responsive and I ran an A/F guage and it...

    670 Street Avenger and Flat Cam Lobe

    I recently lost an exhaust cam lobe in my 318. When this happened it caused the exhaust pressure to ram out of the carb. We were able to get the new cam and lifters broke in but it didn't want to idle. We thought it was a vacuum issue. If you would try to idle it would die and if you did get...
