    Valve Spring durability

    IQ, interesting results..! I had planned on porting the heads years ago but couldn't afford it till now... As for my suspension, I have the cal-tracs ready to install. Im waiting to buy the single leaf springs that are recommended. I can fit a 12" tire and if I mini tub, approach 15"'s so I'm...

    Valve Spring durability

    -continued- I wanted to get my power squared away before suspension mods. I'm trying to keep my car untubbed. All the big block Chevy guys around here that are in the 9's run tubbed rearends. I know it's a difficult thing to do but I figured I'd try and if that doesn't do it I could mini tub...

    Valve Spring durability

    I didn't want to list all that went with my question due to the length. Background: my car has a 4.625 stroke and a 4.5 bore. 12.5-1 Pistons, unported Indy legend heads, comp cams .736, [email protected]. Builder that does a lot of Indy work suggested this can as it had good torque down low. He was...

    Valve Spring durability

    My apologies if I'm coming across as a jerk or worse. I am very much "to the point" person and most people aren't. Yeah, I could work on my suspension, or a many number of things. I was simply looking for information specific to my question. If I've offended you, I ask your forgiveness.

    Valve Spring durability

    I don't know what's vague about "Anyone have any experience with cam/valve springs for this amount of lift that street drove theirs, and how long your springs lived?" I do think it's "stupid" to answer a question with a question. Anyone who has run a combo that is similar would also benefit from...

    I've always viewed being a Mopar enthusiast as being part of a brotherhood. I can't imagine not helping my fellow Mopar enthusiasts. If there's something in my experience that can help someone else, I gladly and freely offer my advise. If I don't have an answer to a post, I don't respond. If you...

    Valve Spring durability

    Is this some kind of joke? Questions are answered with questions? Have I stumbled on to one of those "let's see how important I can make myself seem" forums? Slew rate? Why not talk metallurgy and installed height along with harmonics within the valve train.. Why not talk about if you have...

    Street / strip exhaust set-up ?

    I run TTI headers, flow master mufflers. All 4 inch. I also have stock wheel wells. It's possible I could have fit this system with the stock gas tank but I had already put in the fuel cell prior... If you want to hear it, go to YouTube, search for "Alaska Hemi Coronet Idiling", turn yr speakers...

    Car show observations and experiences....

    I've had my car in car shows and of course, those dorks start showing up and talking about what's wrong with my car. I've done virtually everything on my by myself. So when these dorks talk down about my car and discover I'm the owner, the ones dumb enough to question me about my car, I look...

    Valve Spring durability

    Many factors are involved in choosing the right valve spring for your engine. Installed height, seat pressure, open pressure, coil bind etc. following the manufacturer's recommendation for springs for drag racing is fine if you're drag racing. I'm street driving mine. Many more miles than just...

    Valve Spring durability

    I'm am going through my motor. I'm having the heads CNC ported. I'm going to change my cam to something a little bit bigger. I currently have a .736 lift cam with 285 duration at .050. I am going to go to a .785 lift cam with 296 duration at .050. Though these are drag race specifications, my...

    Who uses a ratchet shifter on the street?

    I've had the B&M megashifter in my car for about 15 years. I absolutely love it. I have a reverse manual valve body in my car. When I'm really on the gas, my car accelerates so quickly, I have to shift from 1st to 2nd almost immediately and still try to steer. I really like how I can just bang...

    Street / strip exhaust set-up ?

    I removed my gas tank and put a fuel cell in the trunk. With the extra room, I bought some 4" exhaust pipe, 2 - 90 degree bends, 4 - 45 degree bends, 2 - Flowmaster mufflers. Welded it all up, made some hangers:
