And, to help in that regard: Grade 5 bolts have three hash marks on the head. Grade 8 bolts have six hash marks on the head. I generally use generic (ungraded) stainless bolts for non-critical stuff, since they stay looking nice for a long time. Graded stainless bolts get pricey, but they...

I guess you're right, the Performer Vortec is quite a bit taller than the regular Performer. Dunno why. Joe

I have stainless dual pipes from Mid-America, with stainless Dynomax UltraFlow mufflers. I'm very happy with that set-up. Actually, not only don't they hurt, but the PCV significantly increases engine performance. Applying a vacuum to the crankcase (up to maybe 15 inches or so) will improve...

An Edelbrock Performer Vortech should fit. Joe

Thanks, that at least covers the runner length question. I guess I really need to find a book or something that will describe the details of designing intakes. Joe

I do remember reading something about roller cam bearings a while back. If I recall correctly, the block needed to be modified, since the bearings had a much larger outer diameter than standard cam bearings, and the gains were only really significant at high revs when friction becomes a major...

There are a number of parasitic loads. Dome lights, as buckethead mentioned. Your clock. Your radio, probably, if it has electronic memory for station presets or such. If you want to avoid sparks, do what I did: get one of those switches that attaches between the battery and the cable...

The master cylinder and reservoir are a single casting. You'd have to replace the whole unit, and the C3 master cylinder is signficantly superior to the C4 unit. Actually, the ZR1 used a very similar master cylinder to the C3. I'm not sure if it looks different, but I believe is had a similar...

Well, it's probably too small for your engine, if it's intended for a small 4-banger. And the kit won't line up with your engine and intake. And you need a box for your carb, because the whole carb needs to be pressurized (technically not true, but carbs that are designed specifically for...

Anyone know of a good resource for information about designing intakes? Things like determining the best plenum volume, and the appropriate size and length of the intake runners? Joe

Do you want an emissions-legal (Y-pipe into catalytic converter into a second Y-pipe) exhaust? Or true dual pipes? Only a dual exhaust is going to really sound like a traditional muscle car. That's what I have. I bought a stainless system from Mid-America, and added stainless DynoMax...

Your stock distributor is an HEI distributor. :) Joe

Call John's Corvette Service in Laconia. I'm not sure if he rebuilds them, but if he doesn't, I'm sure he knows someone who does, and John is a stand-up guy. Joe

Vanacor. No, it's not show-car perfect, but it's good enough for me. Joe

I don't think it would be a big problem. You'd need to glass some sort of airbox onto the underside, to mate with your intake. On the other hand, with the rise in the rear, I'm going to do some sort of cowl induction setup... Joe

Man, over five and a half seconds to get to 60? That's the big thing where these cars lose out: in practical performance. Who accellerates for a solid 1/4-mile on the street? Not many. But how many of us have to get up to speed after a stop light or somesuch? With no torque, these little...

Okay, boost basically increases your displacement, without making a mechanical change. You cram more air into the same space. If you run 15 pounds of boost, you've basically doubled your displacement. Sounds great! But do the math... 2L x 2 = 4L 350ci = 5.7L Vette still wins. You'd need...

If I had a machineshop, and someone who could program the electronics, I'd take a try at converting an old tranny, just to see if I could make it work. My left knee is no good, so while I'd like to have a manual, clutches are a big problem... Plus, shifting without taking your hand off the...

I don't mean an automatic with a pushbutton selector (ala Chrysler), or even an automatic that can be shifted manually via pushbuttons (Tiptronic, etc.). While torque converters are nice, automatic transmissions have some trouble handling truly large amounts of power, and are less than...

The car isn't exaclty in wonderful condition. It's already been partially stripped. If anyone is interested, it's located on Rt 109, between Sanford and Wells, just north of the power lines. If you head north from Wells, you'll go under the lines, then over a little bridge, and it's on the...
