It's a 64mm (turbine size) with a 76mm inlet size 50 trim. Just your regular run of the mill Ebay T04E going strong.

And I have debated on seeing how leaf suspension does with a 4 link, adjustable shock, and lowering/de-arched leafs to get rid of the blocks. Not sure how I feel about de-arching the 30yr leafs yet. Biggest reason I wanted to move to coil overs is the truck will be mainly used for road course style racing and spectator drags over drag strip runs. But I need to due something to rid the axle wrap. I have considered the RPW custom billet cams, (they're like $900), or if I could somehow find a stateside company to help me out with it. Biggest issue is still trying to figure out whether or not any head work will help or hurt performance. A port and OS valves could show great numbers on a flow bench, and totally different reflection on a dyno/real power gains. The stocks can be ground to a 294 to my knowledge w/ dome head work, but that's pretty rowdy for the street. I was thinking 272-284 grind area if I went that route on the cam.

I measured the clutch at one point, and can't remember what size it is, but it's definitely bigger than the OE. I would love to be able to get my hands on a light flywheel with the replaceable surface area, but finding one foe this application would probably be difficult, so having the stock one lightened might be the route I go instead. As for the head bolts, I'm still going to try to work with ARP on a set (we think we found a set from a nissan platform that will work), just so I don't risk lifting the head again.

I've been in over my head with customer projects lately, but plan to start back on the truck, hopefully, this weekend.
