i just did mine the 1" works much better have fun tightning them 1/4 to 1/2 turn at a time primarys are in the way here is the ones i got the 3/4 will work but pia to start threads http://www.thunderracing.com/catalog...1&sid=222#P948

 

I originally used those and I felt they weren't getting enough "bite" so I ended up going with the 1" sizing.

 

The 3/4" are a pain in the butt to get the threads started. I'd imagine the 1" are better in that department.

 

do yourself a favor and get the 1" ARP SS w/ the 5/16" heads.

 

While I could tighten the 3/8's heads, there were some clearance issues with the wrench and the primaries. It involved a lot of trickery to get them snugged down. I'd imagine the extra 1/16th of an inch could make *some* difference in how easy it is to tighten them.

 

thx guys...i went with those 1"...ordered them from thunder racing

 

makes a big difference. i can get a box end wrench on every bolt and can even get a socket on some of them.

 

Man that must be nice. If I feel that I'm not happy with my 3/4 x 5/8's I'll definitely pick up a set of those 1 x 5/16's. And what are you guys doing to tighten down that front bolt on the passenger side...the one under the alternator. Are you pulling the alternator off or using a combo to get in there?

 

i use a 1/4" ratchet w/ a short ext or a deep socket, but i can also get the 5/16" wrench on there as well

 

When it comes to that bolt or spark plug, I just pull the alternator, I don't even bother fighting around it.

 

i think thats what i am going to do
