L98 differences?
I have a 1991 L98 coupe and Have always wanted more power. I found a 1987 donor L98 motor that was completely rebuilt with high performance heads, cam, lifters etc. the engine is also including a 700 R transmission. Is this combo compatible with my car? If not, what else can I fit in my car or should I just have mine rebuilt?
thank you

Without knowing exactly what they did, its hard to say what caveats are here. It'll fit and is compatible.
If its a performance engine then your chip must be retuned to run this motor before it will really run well.

I have a chip from Alvin at PCM of NC. I'm sure he can program it for me. This is all I know about the motor I'm looking to buy:
the bore was 4.030, valves I 1.940 and e 1.500. Combustion chamber is 76 ccs. They used a comp cam with tons of specs. Valve timing also has a bunch of specs They used pro magnum 3/8 inch rockers. 9.0 : 1 ratio.
The information shows a ton of other specs.
Do your think this rebuilt L98, auto 700R trans, larger radiator and beefeater rear end. Plus the 1987 Donor car is worth $3000? The fiberglass is all good the interior is rough

your 91 heads are probably better re-evaluate before dropping it in as is
more compression and better cyl head flow helps
if you pull the valve cover off youll see a part # stamped on it. What are the last 3 digits?
