Lt1 -1992 camdrive!
Hi. I can´t find any performance camdrive for my -1992 Lt1. Does anyone know where to buy one?
This is the earlier type of sprocket for the optispark drive. I talked to Summit and they did´nt have any
One more thing. I previously saw a throttlebody for TPI-Lt1 with a unibody type, not dual 52 or 58mm but one big! I can´t find this one either
Anybody knows?
Thanks.

There is no hi-performance timing set for the 92-94 LTX because of the spline drive for the Optispark. No money I guess in a mfgr tooling up to prouduce parts for such a small faction of SBC's.... Espc when even GM dumped the spline drive Opti.
You could do what I did - Which is to convert the car over to a 95-97 pin drive Optispark.
With the Pin Drive Opti you can run any number of double roller chains (elect WP) or the extreme duty (mech drive WP).
The 92 has a few specific things you have to modify that are not required to 93 and 94 Y bodys when changing the Opti drive to the later pin drive set up.
Do a search on my user name - as I just went over them last week for someone else here in C4 Tech.

Cool! Thank you! How are the final finish on the Mono Blade? Does it fit the Lt1/LT4 intake fine beside the matchporting or do i have to mess with the bolt pattern/TPS sensor/throttle cable etc..? I just wonder if it worth the extra to replace my 58mm BBK?
I think i´ll go with the conversion to the LT4 camdrive instead. It feels like a better choise.
Another thing!
I saw that edelbrock has a Lt4 aftermarket intake. I have bought a Lt4 intake for this Lt1 engine because of my AFR #1039´s. But does anyone know if i can get some extras from the Edelbrock version? Or does it run hand in hand with the GM LT4 intake?
Thanks.

Ok i read the thread about Lt4 timing conversion and i have one thing i´m worried about. I just bought this Comp cams custom grind for this engine. But will it fit the Lt4 timing set?
I have taken pictures of the pin and centerhole of the cam,
here you go.
The pin stands out about 14mm ( 0.55" )
And the hole diameter is about the same. Sorry for my low standard of measuring but i was at home and did´nt have the right tools to measure here LOL
Thanks.

Few pics of my AS&M Mono Blade. Bolt pattern, TPS, IAC all fit fine. Throttle linkage (plastic cable cam) was slightly different but nothing some bending on the bracket couldn't fix. As for the machining fit and finish - Judge for your self.
The 58mm Pro Products I had on the car before the Mone Blade.
The modifications you'll need to do a stock LTX intake is you will need to port the throttle opening so it will look like this one which I ported for CF Member blackharleyman.

The stock LT4 intake will work with the new AFR 195 Comp Port heads, it has the same port dimensions and locations as the stock LT1 intake. The stock LT4 heads have different port dimensions, not the intake.

The Eldebrock intake dosen't offer anything performance wise over the GM LT4 except to isolate the runners and plenum. It's just easier to find (as GM stopped mfgr of the LT4 intake). If you already have a GM LT4 intake I'd suggest you stay with it.
STL94LT1 is right. The GM LT4 intake will fit either AFR 195 head with a very little port matching. The LT4 intake I have pics of is one I ported for the 383LT4 w/AFR 195 Comp Port Elims I built for blackharleyman. There are pics in his engine build thread (stickied at the top of C4 tech/performance) of how much material I had to remove from the runners to make it match up. Look in his thread and you'll see it wasn't very much.
My rocker covers are Moroso PN 68326. They will clear roller rockers fine. You will have to modify the drivers side cover to clear the LTX altenator. Below is a diagram with dimensions (listed in inches) and some pics as to how I cut mine up and welded it back.

The early spline drive hole measures .450 but it is bored at a taper to .240 at the rear.... I rember how deep it is.
You'll need to measure yours with something more accurate than a ruler to tell the difference.
Most aftermarket cams have the late model straight .500X 1.062 hole.
