4.0L gear drive?

[WhiteDevil1311]

Does anyone run a gear drive on their I6? I havnt looked for them yet was just wondering per an idea I had.....belt drives came into mind too. Thanks

Not sure what you mean here. Can you be more specific?

[WhiteDevil1311]

Sorry for the timing. It replaces the chain

[WhiteDevil1311]

Its*

I haven't heard of any belt drives, and thee is really no provision for one.

[WhiteDevil1311]

They replace the timing chain set. Ive used em with the sbc and 4.3l gm but always had to remove material to get them to fit but i was wondering if anyone uses/used them. Cool sound but more accurate and zero stretch

[4.3LXJ]

Yes, I know what you mean now. The 4.0 is a very old school motor that has very few options for improved horsepower. Nothing is like a SBC where you can buy race parts at the dollar store

[WhiteDevil1311]

No hp or tq gain just dead nuts timing and no stretch is what im trying to achieve. My bottom end is very tight so I was thinking a gear drive when I do replace the timing chain set.

I don't think they exist for the 4.0

[WhiteDevil1311]

Ok ive been looking and there isnt any out there never was which is mind boggling since the 4.0 is used in alot of different applications

[4.3LXJ]

That is true, lots of them out there. But it is not considered a highly modifiable motor like the SBC

[WhiteDevil1311]

I know which is a shame due to the potential for a nice torque monster to develop out of the motor. The more im learning about them the more I want to build a motor but the expense of truly one off parts will kill me sooner than later

[WhiteDevil1311]

Im on tapatalk and havnt figured out bios yet but you have a 4.3 gm in your xj?

[4.3LXJ]

Yes, I do

[WhiteDevil1311]

Nice im assuming it fit great due to space under the hood.

[4.3LXJ]

Headers were tight, but the rest is a very good fit. That is why I chose it

[WhiteDevil1311]

Nice, very nice. I miss my 4.3L 4x's. Had to fix the vac actuated front diff to a locking throttle cable to keep it engaged but man that little motor worked its way out of all sorts of predicaments.
I had the tbi with the filter on top made going deeper easier.

[4.3LXJ]

Yup, good motors
