An F1X would make for a monster. I only said that because I seem to recall that you said a while back that if you had to do it over you wouldve gone with the F-1A-94...? Or maybe it was something or someone else? I dunno. I can’t even even keep up with which blower is what these days...
I can only imagine that it was a handful already...

Wasn't me. I'm very very happy with my YSI. Makes killer power, does great, super reliable, no issues.

he's already admited he can't keep up with me so might as well enjoy his ysi :p i do forsee us building him a sweet air to water setup though.

Unreal

Agreed on air to water, and new charge piping. I know a guy.

As for can't keep up, I would make a joke about just waiting for your PC to die, but it isn't as funny when my car is dead, so I won't go there.

Seems a lot use Ford Cleveland head studs for 1/2", $190.

I've just drilled/tapped my own block although I opted for Viper studs that cost $360.
These are almost a perfect length match and ARP2000 vs regular 8740 for the Cleveland, and the Clevelands are a little longer apparently.
Plus as a Viper kit...it leaves spares.

ARP state 120lbft for the Viper, although doubt I'll go over 100lbft, 4 bolt setup still. They state 110lbft for the Cleveland kit.

Although it was a slow task doing all of them ! ( I had a guide setup made for all the drilling/tapping operations so less chance of me ******* it up )

I wanted to do the 625's a few years ago, but it seemed like they were like rocking horse **** back then....nowhere I tried to buy could supply, or even give any sort of indication when they'd get stock. Paid 2 different places and waited 3 months each time and got nothing.

For the heads, do all the huge port heads really make a difference to power ? How do they then perform at the lower end ?

Unreal

Went with 285 head ports instead of 305.

If I was doing 1/2" it would be the ARP2000 instead of the 8740, but the cost on the stud kit was $800+, plus the machining. $360 must be just the 1/2" studs, and not include all the other outside bolts/etc.

My builder has the CA625 in stock on the shelf, so no worries on finding/getting them.

$360 was for the Viper studs, so 24 studs in total but yes, only would only cover the 20 main studs you'd use for an LS

I cant really see any need to change the outer M8 fasteners, and that would also only be for a 4 stud in my case.

the 625's do seem to be more readily available now though so do make perfect sense.
