What are those goofy little square holes all the way infront on the heads intake surface? Wink

Other than that the scene looks very familiar. I even get to pull the rockers off tomorrow to try differnt guideplates since I am unhappy with the alignment of the Comps with the LT1 heads(hence the coolant shot Twisted Evil

my intake is dry)

Aha! Reverse cooling. Make sure you yo use loctite 518 when reassembling or you will have to do it again and again.

The guides can be a real pain. I chose to use raised just because they are close to the rocker. Sometimes I have to grind the hole one way or the other to get the proper alignment and that is just part of the deal.

The LT1 valvespacing is a little funky I guess, all the rockers form "V"s with the pushrod ends being closest together. A few of the roller tips are JUST at the edge of valvetips. I am going to try GMPP guideplates because I hear they line up a little better. Those who are really anal insist on Isky adjustables on the LT1.

Here is what I bolted onto my stock shortblock the third package down 190cc http://advancedinduction.com/AiProductsLT1.html, sprung for a few upgrades and the intake porting as well. Hoping for 380+ at the wheels. Should start it for the first time tomorrow. Hit some snags along the way, nicked the front cam bearing had to find on on a saturday afternoon cry baby

, then the headers didn't clear the angle plugs on the aluminum heads.

is this enough information for someone to predict horsepower and torque on a calculator? the car weighs exactly 3812 lbs. im going to guess around 350 horsepower and 380-400 ft lbs of torque.
