Sold the roadster and have been working on the kid's '63 Econoline van. Apparently that wasn't enough, so I tore the top end off the 390 in the '68 last night. There were 2 things that bugged me (ok, there's more than that) when I finished this car 9 years ago (500 miles ago). The intake was a stock FE dual plane, and the valve train was stock. When you nail it in 1st gear and get a few rpm's on it one of two things MAY happen. Light the tires up and watch the R's climb REAL fast, and/or break the ends off the rocker shafts.
I've had a Holley Street Dominator intake around for some time, and I decided it needed some exercise. That's what started all this. Now I know that putting this on will likely add 30 or more HP and make my traction problem worse, but that won't stop me. Maybe I can take it to one of those Nopi ricer-fests and enter it in the burnout contests. Or maybe I get lucky and the horsepower comes in higher and actually MOVES the car forward.
Anyhow, I started thinking that since it's such a PIA to remove the export brace, master cylinder, valve covers, valvetrain, etc, to swap an intake, I better upgrade the valvetrain. I'd hate to spin this sucker up and break a shaft and go through all this again. This really is a good time to build dinosaur FE's... there's more stuff available now than ever before. I ordered up billet end supports, rocker stands, rocker spacers and an ARP rocker stud kit to keep everything where it should be.  
Damn, now I'm going to need a new clutch and flywheel.

I have a dial-a-jet on the primaries, and it's been a LONG time since I checked it, so it was due. Come to find out, it was set at the equivalent to 67's. I opened it up to 74's and took it out again. Better, but not good enough. I hate having to park it for the night, because I wind up spending the night going over all the possible causes in my mind. Sunday I decided to spend the day dialing it in. Went out and bought another timing light since the mooch I let borrow it last time didn't return it.
