ps - the fan belt problem was fixed in many cases by slitting a section of radiator hose, and sliding it over the coils. the rubber absorbed enough energy to keep the spring from resonating, similar to the metal damper in valve springs.

Thanks Moper, that's the best explanation I've ever heard. I saw something like that at a diesel engine OEM once, but I understand it alot better now. There was a spring pulling the fan belts tight. Turns out, it's natural frequency happened to be the same as the engine at high idle. You...

FWIW, I shift at 5,500. I forget where I heard it, but the worst spring surge supposedly happens far below red line, and that's why they put dampers and such in there. I think it's a slightly different issue than valve float, and can cause broken stuff from fatigue. but I digress. I mainly...

I'll second that. My edelbrock heads had significant runout in the seats, so I got a Hughes 5 angle valve job on them, and back cut the valves. I ported them myself, following the recipe Steve Dulcich laid out over several MP and Car Craft articles. Pushrod pinch and exhaust port size are...

I have an Eagle crank in a 408 and have put 5,000+ miles on it, and dozens of high 12 sec et passes in the 1/4 mi. I shift at 5,500 and had all the balancing and machining by Hughes Engines. no problems. I also helped build a 383 SBC with an Eagle crank. It was a mostly strip car, running...

Were these Lunati's from a few years ago? It seems like there was a rash of flat tappets wiping out regardless of maker, lift, etc.... I heard speculation that many companies were getting cheap lifters from the same places, and they had lots of metalurgical problems. There were also...

Many people buy hydraulics because of noise, and because they are afraid of lashing valves all the time. First, even with a hydraulic cam, you should still check pushrod height, or use adjustable rockers to get the preload right. Most of the horror stories about frequent lashing on solids are...

Thanks. I took it on a grain scale last summer with my fat azz and a trunk full of tools, and it was about 3650 pounds. I guess it could be more like 3300. I just had the new EFI system on it, and it was a little buggy. I didn't dare go too far without bringing a full shop along. Someday...

mid teens around town, high teens on the highway averaging 75mph. this is rare - I can't keep my foot out of it most of the time. My highway mileage suffers because it's a higher stall converter than it should have for a 2.76 gear. It's in drydock right now for an overdrive and 3.23s. It's...

Comp 918 blue stripe beehive springs used with a Hughes hyrdraulic street roller on ported Edelbrock LA RPM heads. Took a little head scratching, but not too tough, since the heads are set up with 2.02"/1.60" Chevy tall race valves from Eddy. I've been meaning to post this for some time and...

I have heard this is possible? I am thinking about using an Eddelbrock ProFlo XT intake (efi tunnel ram), but Eddy only makes it for the Big Block RB mopars.... PH
