1974 620 Ultra Quiet Exhaust: Adapt 720? or?

17 December 2017 - 01:13 AM

I do interstate driving over 4500 rpm and do not want any kind of exhaust drone - seems like I have an OE muffler on mine an it gives off only the faintest hum at that speed.


Even sticking with OEM style mufflers is not a guarantee.  For instance, the Suzuki Swift variants Walker SoundFX is terrible - very noisy mufflers.  Only the Walker stainless steel mufflers are quiet.


I was looking at Ranger and S10 exhaust parts and it looks like both are RHS systems (620 is LHS.)


The 720 might be good for the muffler/tailpipe?  Bosal has a welded 283-903 for about $110 shipped from RA.  (muffler has a front flange, but that could be cut off or welded.




I don't want to go to a muffler shop and get something bent because I would be really

pissed for a $300 job for muffler/tailpipe that was loud - which is what most people want. 

I could weld up a tailpipe but that leaves the muffler.


So that leaves me sourcing a muffler.


I looked at a lot of threads and one referenced a quiet muffler choice for a King Cab.  It didn't have much in the way of responses.


NOTE on PIPE SIZES:  The S10 and Rangers use a 2.25 exhaust and 2.0 tailpipe for their 2.0 liter engines.  I'm guessing they are 100 hp, so the 70 hp L18 could manage with a 2.0 and 1.75/1.50 pipe sizes.




EDIT:  I'm guessing 520/521 exhaust might be a direct fit more or less.  Yes, older, but past discoveries would apply.


NOTE:  It doesn't seem like there is any attempts to find modern parts that will fit w/minor modification.  Everyone is getting loud / performance stuff either DIY or from muffler shops. 


I admit working on exhaust is a RPITA and virtually impossible if you don't have the tools/equipment.  I have all the tools/welders but not the lift.  I've done fabbed exhaust working off jack stands and I just don't have the stomach for it anymore.  But it backed into a corner, I guess I'll have to submit...

74 620 Throttle Cable wore thru sheath - Options?

Looks like NLA.


Finding used or NOS sucks because truck is down.


Any clever sheath repairs?  (Would be temp since the cable is frayed where previous monkeys looped it though a MonoJet linkage with a plastic tie...)





1980 720 4-cyl L20B 5-speed pics

Here are some pics for reference purposes.  I cannot vouch that this transmission is what is stated in the title - I bought on the word of Hooper's Auto Salvage in NC.




4-spd 5-spd Shifter arm interchangeability (bot 5spd w/o arm)

20 August 2017 - 05:42 AM

I just got a 1980 720 L29B 2wd 5-speed w/o a shifter arm.


Is there any chance the shifter from my 4 speed will fit?  (or am I screwed?)

I wanted to close out an open problem thread that I just solved.
