    How much spring pressure is too much?

    Thanks for the tip, I'll be sure to pull the inner springs for break-in. That was what I was wondering about the life of the cam, thanks flyfish. :-D

    How much spring pressure is too much?

    Thanks for the info, it sounds like the springs I have should work okay with that cam. I guess what I'm asking is with the higher pressures, does the cam and lifter set turn into a wear item, where it will need to be replaced every so often? I'm assuming that it breaks-in okay, I use the...

    How much spring pressure is too much?

    I recently spoke to Lunati over the phone about one of their cams (10200705, the big Voodoo for a small block) and the set of Comp 987-16 valve springs I got as a gift. With the 1.6 rockers I have on my Edelbrock heads and at a 1.800" installed height, the pressures work out to be 120 lbs...

    383/400 stock stroke recipe's!

    My dad's 71 Challenger...Shortblock was built in the early 80s, with a shoestring budget. It gets torn down about once a decade to check it over, but has been bulletproof. Early 70s 400, forged 383 crank, block has been decked a lot, stock rods/pistons, don't know the CR, cranking compression...

    Yet another cam recommedation thread...

    I got everything pulled down the rest of the way today and popped the cam out. The stamping on the back reads EDEL 7177, so it looks like it's the Edelbrock Perf RPM cam. Here's the specs: #7177 ENGINE: CHRYSLER 318-340-360 V8 RPM RANGE: 1500-6500 Duration at 0.006" Lift: Intake: 308°...

    Yet another cam recommedation thread...

    I dug out the dial indicator, but couldn't find the degree wheel, so all I have are lift figures. I haven't had an opportunity to pull it down further yet. The intake shows .320 at the lobe and the exhaust .338. I figured that to be about .480 and .507 at the valve with 1.5 rockers. I should...

    Yet another cam recommedation thread...

    I've torn the engine I got with the Duster down to the short block and don't want to roll the dice on the mystery cam that's in there, so I'm looking for some suggestions for a cam. The combo is a little odd, but gearing may change down the road... 74 Duster, probably will be around 3200 with...

    Best ET

    Lessee here... Last time I was out, the car ran: 13.869 @ 99.71 MPH with a 2.00 60ft Found out just over the past week or so that this was run on just the primaries (secondaries weren't opening) and a distributor with screwed up mechanical advance (stuck!), which is beyond repair. I've...
