Default Upgrade Time

Decided I wanted to make more power and upgrade some things on the car. New specs are as follows:

AFR 227 LT4 Heads with 2.125 valves, new springs, etc. with additional porting by Tony Mamo
Single Plane Intake
237/251 .632/.614 114 LSA Cam
Johnson Short Travel Lifters
FTI TH400 Lvl 4.5 Transmission
Holley Dominator ECU
Race Wire Solutions Switch Panel and Control Board
Upgraded to 3.7 Pulley for F-1A Procharger
Strange Front and Rear Brakes

Sumped Fuel Tank with MagnaFuel Pump
Battery Relocation to the Trunk
Autometer Gauges to Replace Factory Cluster
Corbeau Seats

I'm pretty interested to see how much power this new combo will make. Hoping for some pretty stout numbers from it. Engine is just about ready to go back in the car. Waiting on new pushrods from Manley to come in. Also, waiting on items from Race Wire Solutions and need to measure for new Driveshaft. Should be a fun car no matter what it puts down.

When you replace your heads, is there some extra work you have to do to the block?

Nothing extra to do when I'm swapping them in. Obviously will verify proper piston to valve clearance exists. Which it should but definitely want to check with this cam and larger intake valves.

Definitely a big intake valve but was recommended by Tony for my setup and goals. Bore is 4.030.
