Got it running and have cam broken in. Started right up with no leaks so far, except for a pesky exhaust leak on the left header flange. As soon as I get the inner valve springs back in, I will drive it and seat the rings. Looking forward to trying out the TKO500 trans.
Guess I need to update my sig, and post some pics!
Hope to get some pics up tomorrow. Car is a '71 that is in the process of getting painted.
The forum has been a big help with my tech questions. My goal was a factory LS6 appearance under a stock BB hood, but with better power. Motor has a 4340 Scat steel crank, SRP 10.2 to 1 pistons, GMPP alum heads, factory low rise LS6 intake, and a solid FT cam.
I have a Keisler modified Tremec 5 speed, Centerforce DF clutch and 3.36 gears. I will take if for a spin tomorrow. Should be a blast to drive once it is finished.
I spoke with Harold Brookshire and he recommended one similar to the 243/251 that a lot of guys on the Chevelle Forum use. He thought with my intake, I would be better to use a single pattern. Cam is 243/243 @050 with .586 lift on a 110 LSA. Has a nice sound at idle and crisp throttle response.
I have heard different lash settings for these cams. The book says .024 or .026. Not sure if that is hot or cold. I have them at .020 for initial start up. What lash are you running with yours?
The cam card said .026 but I lash them at a tight .024. I have plenty of low end as it is so I figure I'll set it up to soften that a bit & max out mid-range & top end. With your extra inches you'll pull real hard right off idle. PLEASE post pics or vids if you can- I'd love to hear that thing sing!
Looking good Doug. I like the color of the coating on your headers. Mine have the silver coating & they look nice but there's not alot of variety under my hood- aluminum/chrome tones w/ some orange showing from the block. What brand are the headers themselves? I'm curious because Hedman makes the only 2" primaries for our cars that I know of.
They are Hedman headers. I had a shop south of Atlanta coat them. I like the look of the black for my car. The second tube needed a little clearancing for the steering gear.
That's interesting- I have a solid 1/4" clearance on that tube but had to put a slight dimple on a passenger side tube where it was tapping the frame at idle. So, are the valve covers going to be Chevy orange?
Good so far, but have not gotten it out of the neighborhood yet. I am in the middle of installing the inner valve springs, and fixing a header gasket leak. Should have a much better answer this weekend. It certainly has a more righteous idle than it used to!
