General 302 questions

[curtis73]

Unit 5302 says::::Bore/Stroke is 4"x3". A common .030 overbore will bump the 302 out to a 306, not a 307........


Crap. I'll bet a .040" overbore makes a 308. Oh well. I'll get it close and call it a 307, but use a Fox-body "5.0" emblem. I even have ideas about grafting the top half of an HEI onto a Ford distributor shaft. That will really throw people off. I can see it now; "is that a Buick? Caddy?" I'm also going with an EFI setup, but I'll plumb it into a carb manifold or maybe a hilborn stack. The factory EFI is too much of a dead giveaway.

I guess if I'm nervous about the bottom end I could use a main girdle thingy.

I assume (since the newer blocks are roller cam) that the 5.0 blocks sold in Summit are for rollers. They are advertised as "some of the last 5.0 blocks before the switch to 4.6," so I assume they are. They seem like a steal at $300 but maybe that's just me.

OH.... I almost forgot. Any factory 5.0s with aluminum heads? If so, are they a good choice to modify, or should I spring for Twisted wedge or Edelbrock heads?

Thanks for the info. Keep it coming!
