OK, So this is where I am at with this car..............Drove the CRAP out of it (~15K miles) since this adventure. I kept having a problem burning up Plug wires, but other than that runs very strong. The lesson learned with the wires on the LT motor for me is to ALWAYS use the stock wire looms and dont' worry about after market solutions. It appears that stock works best!...............I also understand that there is ALWAYS an exception or exceptions to the rule. I also had issues and still do on this car and the 91 of making the Composite valve covers work on AFR heads, AFR heads are not very Composite Valve cover friendly IMHO and I wish there was a common matting surface for them or an adapter of some type that would make this transision more seamless to the end users, rather than modifying the valve covers and retaining bolt modifications.

Moving forward, I had an issue with my 91 Vette (White One) about three years ago coming back from Corvette's a Carlisle in where I blew a head gasket. After sitting up for two years, Clif (Will's Brother) Built a 383 Super Ram motor with the parts that I had (Will Spec'd out the motor for him) and it's a nice smoke machine. (Just got it back up here from GA about three weeks ago).

AND NOW!............I bought Grand Sport #091 which is a Red Gut Convertible and I've allowed both Will AND Clif to talk me into putting this motor in the GS. SO, The GS is down in GA getting completely disassembled for paint. The stock GS Paint got beat up pretty good in the Hot Florida Sun, but after all new paint, powder coating, top, seals, badges, stripes and "What Not"...........Clif is going to drop this 383 in the car and I'll probably just part out the rest of it on here.

SO, Not to be completely long winded, I could take the LT4 to the track for a run down south, but I'm more focused no the GS getting done by Mar

ch, April at the latest. And THAT Car, will go to the track for a run down the 1/4 if Will decides that he'll do that for me.

As always, thanks and I'll see if I can get some info up on the Super Ram 383 in the 91. Clif had a local guy who owns a Land and Sea Dyno in GA put the car up right after he finished the motor. I don't have the Dyno sheet but he said that it made 336 HP and 400 TQ at the rear.
