Welcome to our show Unsealed: Life Beyond the Bolts! 

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

This Week

Kate has spent the week catching up on all things Crate Insider while also finishing her 2nd Air Bnb. You can check out her first one at http://rtownretreat.com/. We don’t even ask Steve anymore, we know he is playing catch up on rebuilding engines. We had a lot of wins from the Racelogic Chassis School class this week, to check out Racelogic for yourself click here.

Questions Asked On The Show

Barometric pressure and weather conditions… As we are in upstate ny.. Moisture affects some of the fuel to air ratio .. You mentioned earlier that jetting is not recommended… But engines here seem to want a jet change as day turns to night…Something recommended
What’s the best oil to run with a 602?
With a anti reversion on a 604 crate latemodel with schoenfield headers do you recommend any exhaust past the anti reversions?
How much permatex should I use as a header gasket?
You just said not to run pipe past the reversion muffler. I run pavement and was wondering if I’m wasting my money using them if I run 36” straight pipes after the reversion?
How many race days should we get on our 602 before we rebuild we run 50 lap races on 1/4 to 3/8 mile oval?
How many races before a 602 should be refreshed?
How much total ignition time we run 35?
Steve, besides the obvious bolt pattern difference, what’s the difference between crate headers and standard 23 degree?
Steve on the 525 you done for me the last 2 races we have run my headers have been glowing red but never before ?? Any suggestions ??
Best balancer or damper for a 602 in a asphalt modified?
On a 602 crate motor… There has been talk in our pits about jet coating the headers.. Pros an cons?

at what compression ratio do u need to start running good gas i have a open 355 with just some flat top pistons 9.5 10 to 1 area with dart sportsman heads i red somewhere that the 602s ran just as good or better on the low octane gas so i been running 93 and haven’t noticed that much difference question is really at what compression ratio do u benefit from the higher octane an will it hurt my motor running on the 93?
What do u think about the kit that take the wind out of crank case?
