Re: Suburban is officially under the knife...

The "rod knock" (if that's what it was) may have went away, but there were some odd issues with oil pressure when driving down the road, good OP, bad OP, then no OP, then good OP again. It still felt very strong, but something just wasn't quite right.

I took it to the only guy whom I trust to work on my stuff, so he could tear the oil pan off and do a little investigating... Long stringy non-magnetic shavings were found in the oil pan. oh ****. I was somewhat expecting this but I was hoping to get lucky, lol. The bottom end, however, appeared to be in good shape, but I knew it had to come out.

Might as well throw some good parts in it while it's being rebuilt, right? My plans were to have a stone reliable, 87 octane torque monster that I could safely tow with. After all, what good is a 3/4 ton burb with a big block if you can't tow a house with it?

Much to the chagrin of the performance community, I am staying with the stock peanut port heads and TBI, which means the stock intake on this GenV 454. However, I have ordered the K11-412-8 266HR full roller conversion kit and a custom chip, as soon as I know if I need to overbore, I'll be picking up Keith Black 12cc dome pistons to bump the compression to around 8.75:1. Basically I will lose some parasitic drag and gain some reliability, driveability, and HP/TQ.

I know I probably could have went a bit more wild with it, but with some tricks during the build it should be a great driving rig. More pics to come.
