After being the victim of an upper intake failure followed by a rod bearing failure 70 miles later, my bonnie is finally on the road again. And what a difference!!! I have spent the last 3 weeks rebuilding the motor. The block, lower intake, and heads were hot tanked. The crank got reground. The rods and heads were both reconditioned. The pistons, rings, all bearings and bushings, freeze plugs, water pump, oil pump, timing set, and upper intake (Doorman) were all replaced. As well as a drilled 180 t-stat. Felpro head gaskets were used as well as GM aluminum LIM gaskets.
Now for the performance part. The heads and LIM were both gasket match ported and polished. I did some modifications to the runners in the UIM. We built a from header with 1.5" runners into a 2" pipe so that it matches the size of the rear manifold. I removed the MAF screen. Gutted the airbox as well as opened up the area behind the headlight. Removed the AC compressor and made a custom bracket and pully for it. Using a 9060980 Gatorback belt. And I blocked the EGR and ran it to the airbox to draw cold air. Im not sure if that was a good idea or not though? I also painted the engine dark Ford blue. The valve covers, engien cover, and various brackets were painted with a mixture of the blue Metal Speck paint and Black Textured Metallic paint from Duplicolor. The combination of the 2 colors turned out really nice. I have some pictures on my phone that I will try and figure out how to transfer and post.
After fighting one thing after another, The car finally fired up today. The results left me with a BIG smile
This thing pulls real hard at 4000 RPM+. I can fell a big increase in midrange horsepower. Its feels like I lost some low end which is probably due to my UIM mod. I am going to try and find a used stock runner to through back in and maybe do some for messing around with it. My buddy has a Regal GS with a K&N. We are going to line them up to get a base line as far as estimating the horsepower and performace increase compared to the Regal which ran a 15.1 on a 100*F day with the headlight out.
have a couple of questions for you N/A guys. I plan for my next 2 mods do get the L67 coils and have the PCM programed. Who do you recommend for the PCM. I was leaning toward Intense, but I wanted some different opinions. I have plans for more in the future. Some BIG plans
