EP126 Cooling Tips, Spring Pressure, and a Memorial Race Announcement

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?

Welcome to the Racing Insider’s Podcast! Each week, Kate Dillon from Crate Insider and Steve Hendren from Hendren Racing Engines go live on the Crate Insider Facebook page  and Crate Insider YouTube Channel to chat about world events, random things, and to answer tech questions.

In this episode Kate and Steve do a recap of their weeks and answer some awesome tech questions about exhaust leaks, dynos, buying used crate engines, and ignition!

QUESTIONS ASKED ON THE SHOW

Is the cooling fan with bolt up blades worth the money and does it cool?

Are Stainless headers for a 604 or Coated headers any difference on Dyno?

What is the absolute best carb for an e85 carb as well as what is the best care for e85 during winter months (not racing months)?

360 Sprintcar division in Australia changed to Prosprint to allow CT525 Crate. Thoughts? How many nights you get off one?

How long does it normally take to dyno?

Is bigger always better? Cfm wise for a 604 on e85?

Also what is basic week to week maintenance on a 604 well any engine really?

Check timing after every race? Or is it like that one cooking deal... set it and forget it?

Didn’t Steve say something here a while back about running a dish washing liquid in the coolant to do the same thing as water wetter?

I have a header exhaust leak right where the tubes connect to collector. Should I be concerned? Leak is small.

Running 525 on e85and lost fuel pressure had new foam in fuel cell new fuel filter and had all lines cleaned, can the waterman reverse mount pumps go bad or the regulator? What’s a good place to start troubleshooting?

A guy told me he adjusts the lifters on a 602 at 1/8 of a turn pre load because the engine is cold and the lifter isn’t pumped up yet. Would that classify him as an idiot??

What should some one look out for when going the 604 road. Used needing a freshened vs new?

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?
