    Valve spring question: I'm on the verge of ordering my cam, but thought I better sort my valve springs out first. The original flat tappet that I smoked was a .485/.485 lift and I didn't ever change the stock springs. I figured I could probably get away with it under 500. Almost every roller...

    Working out my compression ratio today. Looks like I had guessed a little high. Came out to 8.6:1. I'm sure there's a margin of error in there but that's about as close as I can get with my rudamentry dial indicator and feeler gauge. Piston measures right about .033 in the hole. Took the piston...

    Perusing rockauto this morning and adding things to my perpetual cart I came across this melling retrofit roller cam. I didn't know rockauto sold these or really any "performance" aftermarket parts. I've only ever bought oem parts from them. Does anyone have any experience or knowledge of...

    That's not much different than stock. I think I'd want a wider lsa in hopes of a smoother idle. The mpg's would be a welcomed addition.

    I haven't picked another cam yet. I won't until I get into it and figure out my cr (hopefully this weekend). The vortec heads are more desirable, I had only toyed with the idea of going back to the peanut ports when I decided on the turbo and the desire to keep it on premium 91 and not e85...

    Thanks. I have been kicking around the idea of going back to the gen 5 heads for the sake of a lower compression ratio. When I get around to figuring out my cr I'll make that decision. It seems like a step backwards, but it's still getting a cam and the turbo will help pull it along.

    Compression ratio question: I haven't had a chance to tear it all down yet, but I have been trying to get a good "ball park" number of my compression ratio with the gen 6 heads. I know the gen 5 with peanut ports had about an 8:1. Has anyone on here simply bolted gen 6 heads on a stock gen 5...

    I'm not sure how prevalent E-85 is my area. My biggest concern with E-85 and the reason I hadn't really considered it is because of access to it. Not just where I live, but where I camp and pull my trailer. Not too mention fuel economy. Hard to believe it could get worse than it currently is...

    Thank you, I definitely will.

    I did the initial break in when I put the last cam in. I ran it at 2000-2200 for about 25-30 minutes. I don't think my neighbors appreciated it all that much. I had just finished the exhaust and the buffalo's not what you'd call quiet. There's nothing quite like the rumble of a big block Chevy...

    Thank you, this does make sense. Now that I have the engine out I can spend some time dialing everything in like it's compression ratio. Off the cuff, and with the smaller combustion chambers of the gen 6 heads I figure it's somewhere in the low 9's. I talked to someone at comp a little while...

    Well I finally got around to pulling the engine. Haven't had a chance to dive in yet, but I will say the cylinder bores are in great shape. The engine only has about 110k miles on it. I'm hoping for a quick turn around on getting it back in. I'll try to update as I go. I don't get a lot of time...

    Haven't dropped the oil pan yet or cut open the filter, but no sparkles whatsoever in the oil that I drained. I fully expecting glitter. I would imagine a full tear is probably on the docket, but I think until I get time for that I'm just going to keep pulling it apart a step at a time. I'm...

    It's been a stretch, but I finally had a chance to dive into the buffalo and diagnose the problem. Here it is, #7 exhaust.

    What have you towed lately

    Towed fine through town, got out on the interstate and stepped on it to get up to speed and it started popping and backfiring through the intake. Haven't had the chance to dive in yet, but I did pop the valve covers and everything was intact as I set it. Assuming at this point it's a lifter or...
