[Doc Holiday]

Hey dudes, i got a 20r in my truck and i relly dont wana change the engine, i know ii will be lacking power cause i am gona be locked front and rear with 36 tsl swampers and 5.29 gears, single transfer case, is there a big difference between the 20r and the 22r, are there any mods i can do to my 20r that will give me more horsepower and tourqe, i also hear that 20r is a reliable engine.....

header and EFI swap

you cant put efi on a 20R

a 20R is good for 300,000 miles


best thing you can do to get a BIG improvement is a header  and a weber carb

my bad i aint quite awake yet

About the best thing you could do with a 20r and running tires that size is to regear the axles as low as possible.

he's got 5.29's

Yeah I read that right after posting that, this boy spreads it around.

Get a header, Thorleys are nice and an agreeable price. Nice RV cam, weber carb, maybe change the timing chain while you're at it. You should be set.

Twisted Minis, is that an airbagged 3rd gen in your avatar?  Looks like you're layin some frame there   I loved my 81, and it may live again, but with a hybrid this time     maybe even a turbo

Oh yes you can.................. it's just a major pita, but I still plan on doing it, just for fun!

Did someone say FI hybrid?? 

[TRHS1980]

Oh, and btw, from what I've read/experienced... the performance difference between a 20R and a 22R is very small... a little more torque on a 22R, a little more top end on a 20R... also 20R has dual row timing with METAL backed guides  So it can be said the 20R is a more reliable engine. As far as a trial rig is concerned, get yourself another t/c and you'll have plenty of power...

Its a bagged first gen. Its also bodydropped. Its a fun project. This is the fullsize picture.

And my motor is relatively stock. Rebuilt with a cam and double row timing chain, and a Doug Thorley header that sits about 1/16" off the ground. It would be cool to have a turbo or something, but I worked so hard to keep the motor under the stock hood without cutting a hole that I'm just goign to leave it.

That's sooooo low man!  How'd you do the bags in front?  Did you have to go custom or does somebody actually make a kit?  Mine was only dropped a couple inches, but I was mostly concerned with how well it cornered, which ended up being way better than I anticipated for such little modding.  It sits a little high in the front right now cause there's no engine in it, but sits nearly level normally.

Theres a lot of cutting involved to put a bag up front. There is a "kit" but its pretty universal. Its basically some weld on brackets. It stands a total of 47" high at the top of the roof, lol. I'm currently reworking the front suspension. I and rebuilding everything to get more lift. Redesigned the suspension to get about 12 inches of travel, rather than 8.5" because I need almost 10" of lift to clear the tire. I'll get you some pictures of how to put a bag in there if you're interested. I'm putting a big bag up front, 7" diameter, versus the normal 6". But I've got pictures of before and after.
