This if you run a solid roller on the street!

I had a set (forgot what mfg) and yes they did not fit with MSD dist.

The Avenger series is by far the worst built.

I've had a couple custom grinds from Comp.

You can never go too big. Big motors need big cams. :)

I can't count how many motors I've pulled and they all have been from the top.

Ran a GM cast crank at the 600HP level for years. I'd be way more concerned about good rod bolts before a cast crank. Just my $.02.

Don't do it. Worst carb Holley ever made. Better off to get a 3310 series if you are going Holley route.

That's why you measure @ .050" with a degree wheel and dial indicator. Then you get apples to apples.

Same specs above I posted on other site for seat timing.

One thing to consider when running a large solid roller on the street is, spring pressure and keeping lash in check. The last thing you want it hardened needle bearing going through your motor if a lifter fails. That's a really bad thing. I'm pulling a large solid roller I've had in my car for...

Some motors like more initial timing, you can limit the total if needed. If the carb has been rebuilt, the secondary spring may be loose or was never adjusted. Most off idle to WOT bog is caused by a lean spot. Can be accel pump, the sec spring tension or both. Overall jetting will also have an...

Vacuum will add a lot of advance, hence why you set initial and total without vacuum connected. Somewhere (and I say somewhere) between 30-40 deg total (without vac adv) is where most motors like to run. My street car is set at 36 deg. My 13.5:1 race motor is locked at 30 deg. Much depends on...

Also, generally to run a solid roller you will need to machine the spring seat for a larger dia spring, longer valves for more installed height, new pushrods for correct length etc.

Trust me, you are not going to like a 103 on a street car. I would stick with 110 or more.

Ditto on above. We started a '63 Vette that sat for 10+ years once. Pulled plugs, squirted oil in bore. All we did was put some fresh gas in tank and carb. Car fired right up.

Just my $.02 but it has been my experience that a tunnel ram (properly jetted) makes more HP and TQ, even at lower RPM than most single planes I tried. Not just at high RPM. Of course, depending on the type and mfg of tunnel ram. That being said, they can make for a fantastic street and strip...

A spool is needed at a certain HP/TQ level, however. Good buddy of mine is a chassis/rear end builder and when I went to a 700HP motor, he said my posi would not last a month. He was wrong, it lasted only 1 week! Went to a spool and never had a problem since. They are not for daily street cars...

I drive one of my cars on the street w/ a spool and have for years. I have with both slicks and street tires. Street tires are going to be more forgiving on parts. However, I don't think you will have any issues as long as you use a good spool and aftermarket axles, such as Moser, Williams etc.
