    Well, let the fun begin!

    The car was always fun. I did a lot of suspension mods, did quite a few bolt ons to the engine, did car audio...etc. It was fun, handled awesome, sounded awesome, had decent power. But I got a little bored with the power after all these years (best time was a 14.0@98mph). Along with some losses, I figured it was time for a little rebuild.









    The car as it sits now:

    Stock dish. Kind of hurts my compression with the aluminum heads. I had the heads milled down a bit, and got a thinner head gasket to keep compression up. I'm still leaving a lot on the table. You can run 11:1 compression on 93 with those heads. Stock is 9:3:1, I'll be around 9:5:1.

    They came with 9 bolts and 10 bolts. The 9 bolts are much stronger than the 10's. Except my 9 bolt has 2.77's and parts are rare. I'm just going to ditch the whole rear eventually. I'm running Z rated performance tires. Those will be replaced by Nitto DR's once the engine is done.

    Adding all that aluminum will reduce weight big time. Any idea of about how much horsepower you will be adding?

    Thatís respectable, those roller rockers will reduce internal engine friction big time. I hope that black box to the right in the picture has new push rods in it.

    That has the new lifters in it. I ordered an adjustable pushrod so I can see what length will give me correct valve train geometry. Then I will order what size I need. I hope to have her running in a few weeks. I know someone who was running the same exact setup as me, but with a slightly smaller cam, and he went 11.9@114mph.

    I used my mothers Cannon Powershot A710 to record the video.

    Roundeye, it feels great. It is running on the stock tune for now, which thinks I have 21lb injectors when there are 32lb injectors in there. So it runs very rich. I also need a much more aggressive timing curve. My custom chip is coming soon. There is a lot of room to gain more power, but on the stock tune, it ripppppppppppppps! I need to raise my shift points to 6000 rpm. It is shifting 1000 rpms to early because the tranny is still setup for the stock 5000 rpm shift.

    My expertise lies in motorcycles, carburetors, some ignition mapping and reading spark plugs. But I would say to watch that rev limit, you do have the chance of spinning up the crank too high and throwing a rod right out the bottom end. Keep in mind that is the weak link, its still stock.

    The stock bottom end can handle 6000 rpm shifts. When you get to 6500 you're starting to push it. All my valve train is good to 6500 easily, which I would never spin it to though.

    Cool

    As long as you are aware of what the weakest link of the motor/drivetrain is, you can subject the motor and drivetrain to that using those parameters as a limit.
