FFDP, you had said that going to full roller rockers was a money waster, but here's the thing. A trunion kit is about $135, whereas full roller rockers are $350.00, wouldn't you spend the extra 200 and go with the full rockers?

 

No, I wouldn't. Stocker rarely ever fail and just work so I'd rather keep my money.

 

I wouldn't even do the trunion upgrade unless you are getting a .625" lift cam. And even then I see more trunion upgrades galling the shaft than making an improvement. You need a torque convertor. And if that shop let the tuner tell them to order a bigger can rather than tune the cam you wanted, don't go back to that shop or tuner. Period.

Gears are going to be a trade off. Anything bigger than the 3.73 you already have is going to eat mpg. If you need the off line leverage then you are going to have to accept some worse fuel economy.

 

you mentioned a torque converter. I don't want to go to a stall due traveling sometimes up to 60 miles one way and heavy traffic congestion. So with that in mind what do you suggest?

 

 

How about a compromise with 4.10's and a 3200 converter?

 

Yeah I don't if I'm ready to go to that high of a stall right now. Sure, I'd launch off the line, but this is my DD and there are times when my wife or my daughters would be driving it too. So I have to keep it somewhat tame for them also. But you had mentioned a trans cooler, I can't recall but I though Avvy's come stock with a trans cooler as part of the towing package. Now I'm not saying it's adequate, only that they come as OEM.

 

I've had a pain in the *** loose converter (9 1/2") and its just not me. However I would absolutely do a moderately higher stall. I've seen many trucks and cars at the strip run a much slower time than stock because of a lumpy cam although a higher mph and just make a lot of noise doing it (Lmao). You should never do one without the other. I think if you look at a dyno sheet of your setup and see where your cam starts to make good torque you could figure out what will work well when talking to a converter manufacturer. I know there are plenty of them that are tight enough to drive normally and then flash high enough when you nail it. That's your next move imho.

 

yes the towing package did include a small trans cooler. although if you were to do a stall I'd do an aftermarket one to play it safe. although if you don't want to do stall right now, 4.10 gears would help substantially.

 

3,000 rpm converter is plenty driveable for a daily. I think you can adjust how they drive and lock up in the tune. No reason to have to rev it to 4k just to leave a stop sign of course.....I am not suggesting that. But a moderate convertor to work with your cam and 4.10 gears should solve all of your issues....might be able to make the 3.73s work.

I would also highly recommend a Tru-Cool 40k cooler. I have one and it is dead simple to install. The 'towing package' cooler is barely adequate for stock......
