IMO hamilton springs with there retainers are way better than the titanium retainers. There just as strong and way lighter.

I can still drive mine to local pulls ( 5-10 miles). I had to drive her 30 miles home from the last pull when my trailer tire blew. It was very fun to blow through some gears ... only downside is, I had to keep her tached up arround 2500rpm the whole ride. My charger will not make any boost till 2500rpm, so hills were fun

main studs
HD rod bolts
aftermarket rods aren't needed but you could have them shot peened
Have your cam ground from a 24v core
24v lifters

Where to find this piece?

To even be relatively competitive, you need to be 200°+ duration on the cam, 12mm seem to work quite well if they have flat plungers and a 903 cam. 64mm or larger bowl and flycut them, balancing and a girdle are extra, plenty run without them. Block stiffener plates help, weld the crank gear.
