Here’s what I got, here’s what I want to do.

One point for the discussion, a '92 has a 4L60, not a 700R4, and it's slightly more than a name change, but I'm not sure what the differences are. I think the changeover year was 1990, and the changeover to the 4L60E was 1993.

Recipes?

Do you have pics of this motor in a truck ? To see how close the manifolds fit or don't fit ? Thanks

AFAIK, the ram horns won't fit in a truck. The motor is still on my engine stand. It'll most likely be going into my '69 Cadillac chassis.

Me and my buddy have the 1103 cam. I have it in a 327 suburban and he has it in a 350 long bed c10. Its a really good mild cam for heavy vehicles.

Factory vortec cam has less duration than the TBi cam. Factory Vortec cam is 191/196 @ 0.05, factory TBI cam is 194/203 @ 0.050. If I have one apart that is roller compatible I have been known to throw one I have laying around in, but never noticed much of a performance difference. Aluminum head LT1 or stock 96 LT4 cam is a different story though.

Have several lt1 cams and a couple lt4s.
