Wow, this blog topic is so legendary and tons of great info. I have to share our build with you guys.
We have an LS-7 my pops bought from 1991 over the counter. He’s had it ever since with no problems at all.(idk why but he immediately put a flat tappet cam in it 😕)
Recently, we decided to have the entire engine re-built, switched it up, and went with a big Howard’s hydraulic roller cam, .680 lift, 247/252 duration @ .50 lift. Kept the original 990’ heads which now are ported/polished, new valves, 4 angle valve job. Edelbrock Jr. Mid rise single plane intake, Intake is match-flowed to the heads 😎, Hooker 1 7/8 inch super comp. headers down to 3 inch collectors, 950 Holley double pumper carb.
I’m not sure how much power we are pushing but I’m going to say it’s probably the same range as the dyno graph shared by Riverdogs00. If I can figure out how to share pictures and videos to this chat, I’ll share everything we have on our engine. It’s in a 70’ Nova with a TH400, 12 bolt rear end, 4.10 gears.
