In context in this case, “hell of a lot of.” Seems we English speakers come up with myriad grammatical constructions to seem less offensive in certain forums.
Well, mostly I realized my first sentence was likely to come off more negative than funny (I just like, really enjoyed F-Zero GX back in the day!), so I decided to add a folksy salute to the effort to dilute that. And a smiley face, people heckin' love those =)
"Heck" is to "Hell" like "Darn" is to "Damn" (or "Freaking" to “F--ing") - a word that sounds similar but is more polite, to be said in public in more religious places and times.
It's a form of hella which is "hell of" but hecka sounds silly so you get heckin. (Heck is also used as a substitute for fuck sometimes and takes its forms.)
This still doesn't make sense as "hellin" isnt a term in wide use. What makes the most sense is transition from "fuckin". But why not simply use fuckin? Surely invoking sex is less taboo than invoking hell.

Indeed, you have a community that wants to be family friendly but high energy, and so the technique is to start with "fucking", one of the top tier swears, and replace its root word with the lowest tier swears. And part of the charm is that "hell" is barely a taboo topic -- it's part of the Apostle's creed and plenty of sermons, and there's no commandment against its use[1], yet it gets minced to "heck"!
