If i recall right the 300 was a maxidyne and had more tq than the 350 but a 350 had more hp and if geared right would out pull a 300. My thoughts are a 300 is a better off road low rpm lugging engine and a 350 was better narrow power band engine suited to on road duty.

sounds like its geared if your only turning 1700RPM at 70MPH your truck has real tall gearing to keep the factory designed 285L in its sweet spot. When you re cal the pump to a 2100 RPM 300 You will have more top speed but not the needed HP to pull it to 2100rpm. Like I had said before the idea with the 285L and 300L were slow RPM / fast driveline speed. most of the 300L I drove were max 62 MPH trucks. My advice for you would be to first find what trans ratios you have then gear it to run 1800-1900RPM at your desired highway road speed. just be carefull because a 300 may be able to pull a load to 60MPH with little trouble but 70MPH may be flat footed.

my cheeks would be black and blue when I was done mototboating her.....

Send me a pm with details. If I get some time this week I might be able to check it out....

The big over drive can hurt your mpg. Most of the low rpm engines I saw had a T2060,2070. Behind them. Top gear was .60 over drive. And had. 5.02-5.73 rears. This was a common dump truck spec around here. If you bump up your pump to 2100 rpm and don't Chang the gearing, the engine will burn more fuel trying to keep up the fast drive line speeds. It sounds silly but that's how it works. There is a fine line with to much overdrive and not having the power to pull it. If I recall my friend never changed anything but the pump timing and had it calibrated for a 2100rpm maxidyne. I remember i could run it out of fuel in about 11 hrs. and his other truck of simmilar spec still had 1/4 tank left.! That's my .02

Fried of mine turned a 300 low rpm motor into a 2100 rpm motor. That thing drank fuel very fast but pulled better than before. All he did was have a pump shop re cal the pump and set it to a standard 300 timing spec.

I 3rd the motion...

I think the fourms go up and down with the season. Seams winter is the busy time and summer is a little slow. Thats how it is with my work and play time.

happy Bday terry......how many gray hairs this year?

IT HAS Superliner tanks on it and alum rear chunks. red interior, Smells like a fire truck and miss matched parts that was used to make this truck up???

yea that last one is great....thats real deal trucking right there!

yea smoke can be so many things. Is it low on power? you can have bad valve guides, turbo seals, incorrect pump timing, bad injector(s), bad injection pump, worn rings, cracked piston, etc.... best way is to do some basic tests on the engine and pump and hopefully.... or not..... you will find the clue. If these tests dont give you any ideas and if you have time pull the exhaust manafold and see if any of the ports are wet with oil.

LMAO.....David I think you should help him with this one before its to late....I too enjoy Vlad's posts but you opend this can of worms...... LMAO

yea its the spreading of the rails thats the big concern and hard to fix. surface rust is easy. However if its seeing rust on the surface I will bet that its started inbetween. it would be smart to put some POR15 in and let it soak inbetween to slow the rusts progress. Just my .02

Test drive....?

Look here http://www.hps-siliconehoses.com/hps-silicone-45-degree-elbow-coupler-hose.html

the only possible issue I can see is that the passenger side may have diffrent ramp locations on the hood . this is depending on the air cleaner locations and cut out of the hood.. on My RS700L I have the twin tube intake and think that the roller on that side extends out slightly farther than the driver side. regardless its adjustable so it should work for you....

I think you will be good to go. looks like just swaping the old solid mount bracket out and put the new bracket with the rollers in. then put the ramps on the hood.

that looks like it would work. looks like a early superliner as I can see the cut rod ends for the "X brace" i was talking about last night. It has the cut out for clutch cable and has the rollers where they should be. now you just need the ramps to mount on the hood..

If the cable is hard to turn it will wear it out in no time. That key way is just formed. It should be cast or hardened so it can't spin on the cable end

He has a superliner 1 ( round lights)

You can buy silicone hoses from parts stores. Just need to know the I.d. And angle...

Jealous .... Now i need a super liner to go with my rs700l

I may have a picture of me in a bikini. I may have to post that for ya. ......if your lucky...
