Ratio Tek Shift kit installed

[TIM Z]

I wanted to share my experience with my recentley installed shift kit, in my gasser!

Mike reccomended this new kit from Ratio Tek. I'll let him tell the details.

So who am i to go against good advice?

Installed it in my 95 Tahoe sport, 4L60E , 350 TBI , Love it!

The shifts are much crisper, faster. Defintley more fun to drive, they all should shift like this!

Never thought a 4L60E with 154,000 on it would run this great!

You can feel the TQ verter lock up now! A great feature of this kit.

Thanks to Mike for helping me when i was stuck, I owe you!

Now im going to have to put one in all my vehicles!

Next for the Tahoe is Vortec heads, Comp Cam 212-218 and Edelbrock Vortec intake/ 454 TBI.

Just a daily driver nothing special. Keeps My Dmax clean of the winter salt.

Right on! Good looking truck for a 95! ever think about putting a super charger on that thing?:thumb:

Just so you guys know; Steve Younger developed the Allison kit and many more while he was at Transgo. His new company is RatioTek and he is doing some special things for me now. This guy is sharp.

Thanks!

Yeah I'd love to actually put a turbo on it.

I bought it in NC and its rust free.

Right now just going to do heads/ cam.

Also contemplating a Gen III small block.

Gotta get back to work first.

Is the lock-up as harsh with this kit as it is with the TRANSGO HD2 kit? I put one in a 98 305 and it is pretty rough when it locks up.

 

[TIM Z]

No , Not harsh at a all. Very nice feel.

Just a confident engagement,

The unsuspecting prob wouldnt notice at all. Just feels like it went into "fifth" gear

Yep..

 

[TIM Z]

x2, Yes.

They are great stock heads.

100x better than the TBI heads.

Capable of supporting over 400 hp out of the box.

Max lift is only .470 with stock springs , but thats easy to fix.

They are a bolt on 20-40 horse on a TBI motor.

I bought a complete 97 Vortec 350 for 50$

200,000 miles and there is no gunk, engine looks great.

Chevrolet and fuel injection = longevity!

Max lift if you want the valve stem seals to live is only .450 on stock VORTEC's. And don't count out the old TBI heads, a mild port job and they will make almost as much as the VORTEC's do stock(just at a lower RPM). I built a 93 and a 99 for 2 different people. The bottom ends are almost identical in both(just slightly different cams), but the 93 has TBI heads and the 99 has vortecs. Both got a good port job on the heads and intake, and the TBI got the extreme mods. The 99 is in a SUBURBAN and the 93 in a 2500 truck. Empty the SUBURBAN is slightly faster once it gets above 4K, but off the line the TBI will dust it. Put a load on the back and no comparison, the TBI will flat leave the VORTEC BURB. Both of them have 3.73 gears and are 4X4's, but 6K pounds and the BURB felt loaded down and out of breath, but the 2500 can tow 6K in OD(of course that will explain all the carnage it had when I did the built trans in it).
