cant wait to see the outcome, it should move out a wholelot better!
the only thing that catches my eye is the LSA on the cam? i thought low LSA's is not good for boosted setups?

building an engine for street use. For more detailed specifications regarding your specific application or for strip only use, please consult a professional engine builder.
Pistons:
Forged pistons recommended for all applications. Cast and hypereutectic pistons can be used but should be limited to lower horsepower (approx 450-500 hp) applications.
Compression ratio:
For pump gas (91-93 octane) applications, a compression ratio of 8.5:1
to 9:1 is recommended for boost levels of 8-10 psi. Higher octane fuel
will allow you to run higher boost levels, approximately 1 psi for every
2 points of octane. To determine the maximum boost level for your
compression ratio (using pump gas), refer to the enclosed compression
ratio chart.
Heads:
The same rules for normally aspirated engines apply to supercharged
motors. Higher flowing heads will help generate more horsepower than
stock heads. Supercharging produces a percentage gain in horsepower; by starting
with more base horsepower a modified motor will receive a larger total hp gain
(from the same percentage gain).Porting, especially on the exhaust side is recommended. Aluminum heads will allow you to run approximately 1 psi more boost than cast iron
heads due to their ability to dissipate heat.
Cam:
Lobe separation: 112 to 116 degrees
Split pattern: Exhaust duration and lift approximately 10 degrees and .010, respectively, greater than intake. Install cam straight up. Contact a cam manufacturer for lifts and durations that best suit your application.
Crankshaft and rods:
Cast up to 450 horsepower, forged for higher horsepower or for rpm
levels above 6,000 rpm.
Exhaust:
Headers are recommended. The size of headers are dependent on whether you are wanting to create more low end torque or high rpm horsepower.

well...had to work Sat & Sun...didn't really get much done other than cleaning 4 bags full of bolts...
the hot washer at the tranny shop was a waste of time...I really appreciate being able to try it though...it's good for surface filth, but not for caked on varnish...
did p/u the tranny though!
Monday was our wedding anniversary...so no progress last night...even though my wife offered to go clean the engine bay while I finished cleaning parts! I didn't take her up on her offer...I knew better!
She also gave me a card w/ a sprayed in bedliner coupon in it for when I get the turd back on the road!
taking a vacation day today to try and get alot done...with Jerry's help of course...

motor is ready to drop in...
many thanks again to Jerry (cablebandit)!
didn't get as far...as quick as we anticipated today due to a few snags...
thank goodness the dealership had an oil pan gasket in stock...
all in all...a good day!
