Great video Herb! 👍 Kool 2 hear about your experiences with your engine tech.

[@VinoRatRodbuilds]

I'm pretty excited about my engine build I just picked up a set of AFR heads.

[@MMCGRACING]

You will love them , now your gonna spank the Elco for sure lol 💪

[@rustyrods8535]

Good info Herb , I used to always run different heat ranges on the plugs and jets depending on what I was was doing to the motor ..cruising on off the throttle mostly no secondary being used or hard on the throttle with both barrels dumping hard for shorter runs. Herb should do a video on how you set up your vehicle from going from cruising to racing , from the radiator to the rear tires. Great video lots of good info . I not liking the heat and I’m with you …cooling down is cool with me. Shawn RR

Good Stuff my Brother . 😎🤘👍🍺🍺

[@MMCGRACING]

Thanks my brother ✌️🍺🍺🍺🍺

[@CCAutoWorks]

I feel like I need a hotter plug but with these aluminum heads I have I can only find one heat range makes no sense to me autolite was the only thing I found in a iridium but great info thanks for sharing

[@MMCGRACING]

That is hard to believe that the manufacturers don’t offer any other options for that setup, I would do some more research my friend 💪✌️

[@cfmechanic]

I have tried a 3k stall but once I put on a 3500 it was night and day feels perfect

[@MMCGRACING]

I went from a 5500 8 inch to 3800 to 4500 10 inch and I’m on the fence still it cruises good but I think the 60 ft is still down

[@cfmechanic]

@MMCGRACING I believe it. A dragy would be a handy tool for you to test with. Best 150 I spent. I'm sure leaving line at 5500 the car launched alot better before. I'm sure u will get it all tuned in

[@victorlloyd6651]

I had lockout put bushing in now 36 total wow

[@MMCGRACING]

That’s awesome my friend 💪

[@victorlloyd6651]

Car really better

[@MMCGRACING]

Hellll yeah brother ✌️👍
