It's finally time to do the second round of engine mods to the Corvette. I've been daily driving it for over a month now after it's year long hibernation. It's running very good and all the previous mods were well worth the effort totally different car now than when it first came into my life. Time to take it to the next level. All the first stage mods can be found here http://garage.grumpysperformance.com/index.php?threads/new-to-me-84-corvette.15386/
The plan is to install the AFR 0916 cylinder heads and Renegade intake manifold do as much grinding and cleanup work on the stock exhaust manifolds to hopefully create a little more flow and have a 3" y-pipe made to help relieve the immediate back pressure right after the manifolds. This will complement the Crane Cams 114132 installed and all the first stage mods I already did. I will attempt to use a air/fuel ratio gauge to dial in fuel pressure and fuel injector size to give it the fuel it needs/wants. I've had good luck using an A/F gauge in the past with my turbo cars dialing them in so I'm hoping I can put one to good use on the Vette too.
Here a few pics of the car and the parts
So I'm actually starting with some maintenance items beginning with replacing the oil pan gasket which I got off tonight. Block is all cleaned off and ready to accept the new gasket after I put some fresh paint on the pan tomorrow morning. I don't think anybody wants to see a picture of the pan, but I was very happy to see how clean it was on the inside and bottom. I can clearly see crosshatch in the bores still and the bottom end appears like previous owners never skipped an oil change.
I will make progress and post pics and info as I go along like specs on the head gaskets compression ratio expectations ect. Next series of pics will be with intake removed and heads coming off which I hope to get done this Saturday(or sooner) and I'll finally know what my actual piston height is at TDC.
