Chevelle updates

[VintageMusclecar]

I’ve been working out the last few bugs on the Chevelle and I have it pretty close to dialed in, there's still just a tiny bit of part-throttle carb tuning to reel in.

Yesterday I received a new Crane Xr-i ignition module to replace the one I popped back in `06 when I installed the engine in the car--it really helps if you wire them up correctly. [img]<<GRAEMLIN_URL>>/rolleyes.gif[/img]

I've also been busy making a home-made advance limiter bushing for the distributor that would allow me to bump up the initial timing a bit w/o having too much total.

Anyhow, yesterday I managed to get both items installed. The Crane module really cleaned up the idle (along with the extra few degrees of initial as well) and improved the throttle response. I also got my digital speedometer/e.t. calculator calibrated yesterday, and I made a slight adjustment to the tire pressure on the L60’s.

I took it out today for a few laps around the block, and a brief “clear its throat out” romp (just through 1st gear and a quick shift into 2nd).

Two things to note:

1) The reduced pressure made a major difference in traction—it didn’t roll them over anywhere nearly as bad as it did before—as a matter of fact, I thought my head was going to wind up in the package tray for a moment....) I can’t believe those things hooked as well as they did. I’m honestly impressed with those tires.

2) Putting it bluntly...this thing’s stupid. [img]<<GRAEMLIN_URL>>/naughty.gif[/img]

This is w/o a doubt my all-time favorite build I’ve ever done for myself, and it almost scares me to think that there’s still quite a bit of un-tapped power still waiting in the wings.

I really need to get that 4.56 gear out of there though, it’s total over-kill on this car. A 3.73-4.10 gear would be perfect for it.

If I can somehow manage to pull it off, I'll try to get a ride-along video done before too long and post it up.
