Does anyone know or ever even heard of gear drive being made for a 4.3 ???? I was thinking of puttin it in my xtreme if they make it...

Just guessing, but would a standard small block chevy set work?? Most everything else does.

I'm not completely sure if a gear drive from a SBC would work due to the presence of the balance shaft...

Just curious, why would you want a gear drive? The only real need for one is if you have increased your valve spring pressures and are chewing up timing sets. The stock timing set is quite reliable.

I just love the whining noise ,to make people think it has a blower on it... I may be putting one on my 454 when i`m ready....

why not just go with a blower/supercharger. Not only do you get the whining noise but you get the power too lol.

SB Chevy 4.3 350 Billet Noisy Gear Drive Roller Cam RP$ Found this on Ebay, have no idea if it works though.

^^^ That is a good point. I just checked out the ad and it doesn't really specify wether they are talking about the 4.3 V6 that we have in our blazers now, or the 4.3 V8 that was made by chevy back in the 70's.

Most parts that bolt on the 350, bolt on the 4.3.

The only thing that might cause a problem is the ballance shaft.

You could buy an entire piston/ring/valvetrain upgrade kit for a 5.7L Chevy SBC, and you'll have an extra pair of everything when you're done...

Usually :D

That's why, if I don't do a V8 swap, I'm getting a Vortech supercharger kit for the 350...

to answer 2 of the4 questions so far,,,, The reason for the gear drive is because in good ol NY the blazer will never pass insp legally with a full blower system on it..

i don't think gear drive will work with knock sensors and computer controlled vehicles

I fail to see how a gear drive has any impact on whether or not your truck will pass inspection. And I have seen many vortech CSC blown trucks pass NYS inspection before. It isn't that difficult to pass NYS inspection. Just don't go bypassing emissions devices and you should be ok.

And again, a gear drive won't help you pass... But sure will be noisy!
