QUESTIONS ASKED ON THE SHOW What plug do you recommend for the 604? We run a 602 imca sportmod sealed crate. having issues with distributor moving on us after we run a few laps. also fuel pump keeps coming loose? Thinking of installing the crate muffler on our asphalt prolate. would I install one per side before y pipe or one 4" after y pipe? How often should you change spark plugs? I race crate 602 in the northeast at a very dusty surface, I run Walker 4x14 with a outerwear pre filter. My concern is I wonder if I over oil my filter due to dust concerns, do I over think this? How do you clean an oilless filter? Is a 604 with bad heads worth anything? I have a brand new carburetor. Revs great an runs good in 1st an 2nd. Soon as I get to 3rd an go wide open the car is stumbling but if I back off to 3 quarter throttle it will go but as soon as I get back wide open it's back to stumbling. Also looks like the bowl is losing fuel an is below the sight glass an this is over a 2 day period. Any opinions? So the autolites are pre gaped at about 10 thousands is that ok? Not quite race related but is a podcast better or doing Facebook live as far as reaching people?

QUESTIONS ASKED ON THE SHOW

Will it be ok to choose the pro cam mechanical fuel pump to stop the cause of vapor lock issue because the new gas pumps now all have 10% ethanol in it to use on a carburetor engine?
Moving to a street/super stock class and going to be going with the 604 option. Rules just say must run a Holley 4 barrel carb, no aerosol carbs. Is the Ultra XP basically the way to go? 650 or 750 cfm better for the crate?
I’ve heard you mention the strange twist axles on your personal cars. Are they worth it? Pros and cons?
What’s the best header/muffler combo for a 604 street stock that will make the most torque without getting into a $1700 set of stainless steel headers? Or is the stainless really worth the money in that application?
I want to set the end play on my crate hei distributor shaft. What end play setting would you recommend?
Would you be content buying a the ultra XP new from Holley? Or is there more to be gained getting one from an actual carb guy?
I was always under the impression that “bigger is better” on carb spacers, but I’ve heard people saying being up against some big open motors with a 604, I’ve heard people say shorter usually equals more torque, and I feel like anywhere I can get more torque is critical. So in the case if true, is there “too short” of a spacer?
How much does your 604 carbs cost ? E85 .. Do you have 1 ready to ship or do you need me to ship mine to you to build?
Your thoughts on removing the power valve? Or is that not beneficial at all?
I've heard the newer 602's have valve springs that no longer have a damper. If this is true, are the spring retainers the same on the newer engines.
Does the phenolic plate replace the steel plate or used with the steel plate?
I've always heard open spring pressure is more important then closed seat pressure? Around what should open pressures be on crate 602?
Do I need change anything on a 604 on methanol to run the 6800 rpm over the 6400 rpm?
Any 602 winterizing tips? Back off valve springs /fogging engine?

QUESTIONS ASKED ON THE SHOW

What are your thoughts about bearing spacers and brake drag on the front tires? Are bearing spacers worth it? And how much brake drag is too much? I didn’t like how much resistance there was on the front tires of my car (southern sport mod) to freely rotate so I installed bearing spacers last week. The hubs rotate about 5-6 times freer now (went from about 2 rotations just from a single push of my hand to 10-12) than they did before which I was happy about. But when I hooked the brakes back up there was so much brake drag that the end result didn’t seem to make a difference (back down to two rotations of the hub from a push from my hand). My dad downplays the benefit of the spacers and says that brake drag is normal. So should I leave things the way they are or is there something I can/should do to make this better?
